Half-Bridge Mosfet Driver IC IRS2153(1)D Datasheet

Last Updated on January 1, 2020 by Swagatam 68 Comments

electricity is dangerous warning message

The post details the datasheet, specifications, pinout configurations and a few application circuit for the IC IRS2153 which is a half-bridge IC from Texas Instruments. The unique feature of this half bridge driver is that it does not have to depend on external logic sources for the operations, rather allows configuring its own oscillator through a simple RC network.

The IC IRS2153(1)D which is fundamentally a half-bridge mosfet driver chip can be actually used for a number of different interesting circuit applications such as boost converters, solar compact inverters, and if two of them are coupled can be even configured as a full bridge mosfet driver circuit. Let's learn more about this interesting device.

Main Electrical Specifications

Before we discuss the potential applications of this chip, let's learn a few of its main features first:

  • The chip is designed to withstand and operate with voltages as high as 600V DC (15.4 V Zener clamp on VCC).
  • Consists of an internal built-in oscillator circuit with a 50% fixed duty cycle, while its frequency can be simply determined through two external R/C components (CT, RT programmable oscillator).
  • Consists of a built-in high side driver network which allows a fail-proof conduction of the high-side mosfet (upper mosfet) with the required essential boot-strapped gate voltage.
  • Allows an external shut-down feature to be enforced just by adding an additional transistor stage with the IC (Non-latched shutdown on CT pin (1/6th VCC).  This feature can be very useful for applications where an automatic current or voltage regulation is crucial.
  • The chip also includes a Micropower start-up feature which assures guaranteed initialization even under relatively minimal voltage and current conditions.
  • An internal dead time feature ensures perfect separation between the outputs for fail proof operations.
  • All the the pinouts are ESD protected internally for safeguarding the chip against static voltages during packaging and handling.

Basic Circuit Configuration of the IC

Understanding Pinouts of the Half-Bridge Driver IC IRS2153(1)D

The figure above shows the standard circuit configuration of the proposed half bridge IC. The pinout functions may be understood as follows:

Pin#1 is the Vcc of the IC and is internally clamped to 15.4V for safeguarding the IC from high supply voltages.

The RC network made from RVCC and CVCC has two important functions, the resistor hleps to control the current to the internal zener while the capacitor provides a start up delay to the chip so that the outputs are able to initiate with zero logic until the built-in oscillator has begun oscillating.

The resistor Rt and Ct across pin#2,3,4 is the external RC network which determine the oscillator frequency (duty cycle being fixed to 50% internally).

The following formula can be used for determining the oscillator frequency:

f  = 1/1.453× Rt x Ct

Pin#4 is the ground terminal of the IC.

Pin#7 and pin#5 are the High and Low side outputs of the IC, meaning pin#7 drives the mosfet which is connected with the supply voltage while pin#5 is responsible for driving the mosfet connected with the ground rail.

Pin#8 is terminated with a Cboot capacitor which ensures that the HO and LO never conduct together and also steps-up the required bootstrapped voltage for the HO pinout of the IC.

Application Note:

The main application of this IC hovers around inverters and converter topologies.

One standard inverter application design can be seen in the below given diagram:

The simple inverter design shown above using the IC IRS2153 can be used for driving mains CFL lamps from 12V supplies.

Here the Cboot feature is eliminated because the configuration is an ordinary center tap type inverter which does not call for boot-strapped supply due to the absence of high side mosfet network here.

The transformer may be wound over any standard 27mm E-core type ferrite assembly, as shown below.

    hello dear,
    i am to build a switch mode power supply and thanks for getting me to this page in the blog.
    My specifications are:
    1. Input to smps will be 12v
    2. Output will be 3v
    Presently, IC IR2153 is new to me and i am still learning about it. And one thing, what is the function of PC817 optoisolator ic, in any smps which role does it play?

    Thanks and please help.

      hello sherwin, look for IC 555 buck converter circuit and configure it appropriately as per the mentioned specs.

      the opto is for feeding the output voltage to the circuit's voltage sensor stage in an isolated manner in order to monitor this feedback data and cut off in case the output tends to go beyond the set safe limit

    Hello sir, i am planning to build a switching power supply. There are some few questions:
    1. what is the frequency rate at which smps'es transformers run.
    2. at which waveform they are operated.
    One thing is that i built my own ferrite transformer for my smps, made it on a ferrite rod from an old radio.
    I wish to use the above driver shown, but at what frequency i must set the circuit to operate the trafo??.
    which diode should i use for trafo. output rectification?
    input to circuit=12v from sla battery, output from circuit 3v 0.7-1amp are my specification.

    Thanks and please help me.

    Reply
    • Swagatam says

      Hello Sherwin, any frequency between 20kHz and 100Khz can be suitably used with ferrite transformers.

      waveform is not critical, ordinary square/rectangle pulses will do

      for the diodes you can BA159

      if you are trying to make a simple buck converter you could make use of IC555 easily, special driver ICs as above may not be required.

    Hello sir,
    while browsing the datasheet of ir2153 ic, i noticed its specs says has a 50% duty cycle.
    now my question is that,
    with whatever values of r and c i use, and assuming a certain frequency at the output,
    would the duty cycle be stable at 50% ?

    i am building an emergency tube light circuit having;
    1. a 2 feet tube 20w
    2. primary center tapped ferrite transformer
    3. inverter config. will be a push-pull type, i will be using the 2153 ic.
    4. power source is 12v sla batt.

    Currently, i am trying this circuit.
    Please help.

      Hello Sherwin,

      whatever may be the values of R and C, the duty cycle will be 50% only the frequency will change.

      you can try the design for the mentioned purpose, if correctly implemented it should work.

    Any troubleshoot tips will be greatly helpful
    Thanks again in advance

    • Swagatam says

      Dear Raj, check and confirm the following basic issues first, check whether the pin7 and pin5 are generating the frequencies correctly using a frequency meter.

      Confirm the above by varying the 4k7 pot, the frequency should also accordingly change at these points in response to the 4k7 adjustments.

      Next connect some kind of load at the output and measure current across each IGBT between their collectors and the positive line….optimize and make it to maximum by gradually adjusting the 4k7 preset.

      Beware that the circuit is not isolated from AC mains, and can give a lethal shock if not taken appropriate precautions.

    Dear sir swagatam
    Thanks for your quick response.
    I checked the ic ir2153 pins with LEDs and they shows flicker in change of frequency with respective 5k rotary pot.
    But on connecting to igbts the ic getting hot and ic get dead.
    Any solution for its
    Thanks 🙂

    Reply
    • Swagatam says

      Dear Raj,

      an LED testing will not show anything, you should test using a frequency meter, the frequency should be above in kHz over the output pins…..may be between 20 kHz to 100kHz depending on the position of the preset 4k7.

      you can confirm by keeping the IGBT gates disconnected from these points.

      but anyway the IGBTs will never load IC outputs since the IGBTs have a high gate resistance…so the IC should not get hot under any circumstances, something could be wrong either with the IC or the connections somewhere.

    I have an interest in this chip. However, the fact that it has no provision for feedback limits its application. Am I wrong? Maybe in just don’t know how to implement the feedback. Please could you share? Thanks

    Reply
    • Swag says

      pin#3 of the IC is the shut down pinout, if you configure the feedback with this pin then you can enable the IC with an aitomatic shut down or a self-regulating facility.

      Reply
    • Mho says

      Please I’m not clear yet. Can you be a little more elaborate. What do you mean by ‘self-regulating facility’? In my opinion, Automatic shutdown is not a true feedback mechanism, as it does not keep the output constant with a change in battery voltage, it only shuts it down completely when the voltage goes beyond a threshold. Is there no means of achieving a real feedback that keeps the output voltage constant?
      Thanks.

      Reply
      • Swag says

        it can be used for the mentioned purpose, because as soon as the the IC would be experiencing the shut down, the output voltage would be experiencing a drop, and this would instantly disable the feedback from the shutdown, allowing the IC to function again…this process would happen extremely rapidly maintaining a constant voltage or current at the output.

        all feedbacks work in this principle, sometimes narrowing of PWM is used instead of shutdown, which is again quite similar because when PWM is narrowed the output voltage drops…

    Dear sir,
    I had like to use two Irs2153DPBF to drive a full bridge (not tried yet)
    How to connect the two IC in order to prevent the second one to oscillate by itself but instead at the same frequency as the first one (but with a 180° phase shift) ?
    I forecast to use CT pin on the second one as a Trig pin by connecting it through a R divider and R to the LO pin of the first one (and if phasing is not good, to use a General Purpose BJT to invert the signal).
    But if you have done it already or know of a solution …

    Bro
    Can we use pin 8 of ir2153 ic in the same way we use pin 4 of the 555 ic (reset pin)? See, I want it to produce a square wave but not continuous, instead bursts of square waves with another ic telling it to stop, say, every half second.

    Reply
    • Swagatam says

      Hi Mooney, Pin#8 is not th reset pin of IR2153, it’s the High side floating supply voltage pin.

      You can use pin#3 instead, each time you ground this pin the IC output will become void instantly, halting the switching process.

    Last comments here were long time ago. I hope I will answered quickly.
    Please I need to understand this ic ir2153 properly. I want to use it for a switched mode power supply and I don’t know how to go about the high side and low side mosfets. What type of mosfets can be used here? Between an enhancement mosfet and a depletion mosfet which is the most suitable?
    And why do we need to connect the source of the high side mosfet to the drain of the low side mosfet as shown in the normal ic ir2153 circuit.

    • Swagatam says

      What type of circuit are you looking for, half bridge or full bridge?
      You will need enhancement type mosfet, and Cboot capacitor can be a 1uF if the frequency is high.

          There’s a formula, you can see it here:

          https://www.homemade-circuits.com/wp-content/uploads/2019/01/full-bridge-bootstrap-capacitor-formula-1.png

          The MOSFETs are connected in the shown manner to enable push pull operation on the load. Load will not work if the MOSFETs are separated. Normally the other end of the load is connected with the ground of the supply, while the MOSFET supply pins are connected with +/- of the source.

          I am not sure about the other variants, you can check the datasheets for the info

I am wondering if maybe my transformer is acting as a short circuit as 20 khz is on the low end for ferrite core any thoughts on this? Also with a dedicated half bridge driver are the 10 ohm resistors necessary between the IC and mosfet gates?

      Hello,

      I guess you are referring to the second circuit. It was taken from one of the reputed pdf articles online, and it seems the circuit is a tested design.
      Yes frequency does matter, and is directly related to the number of primary turns of the transformer. In that case you can try increasing the frequency by reducing the Rt, Ct values.

      Yes a low value gate resistor is recommended for mosfets even if it is driven from a dedicated driver.

        I have 3 turns on the primary and 95 turns on the secondary. It is thick wire which fills a ee42 transformer completely. Do you think this would be ok?

        • Swagatam says

          The number of turns should be exactly as shown in the second diagram, if you are trying to build that circuit. The number of turns cannot be judged, it will need to be either calculated or adjusted through some trial and error.

      Current is not relevant since mosfets gates are used across the outputs. If you increase the frequency of the IC then the output frequency will also change accordingly

      Thank you, and Glad you found the post useful. Yes the IC has an internal 15V zener clamp at pin#1 Vcc. You can use RVcc upto 100K so that the resistor does not burn at high voltages.
