In this post I am going to talk about this very common but very useful voltage regulator IC, that is called IC 7815. This chip is from the famous 78XX series of fixed voltage regulators. So the “15” in this number means this IC will always try to give +15V DC output, no matter what […]
Datasheets and Components
IC IR2184, IR21844 Half-Bridge Driver Circuit Diagram, Datasheet, Working
In this article we are going to learn about one very useful IC called IR2184 or IR21844. This one is a smart half-bridge gate driver IC which we can use for driving both high-side and low-side MOSFETs or IGBTs, mainly when we are making full bridge inverters, or DC motor controllers, or even induction heater […]
INA219 Current Sensor Circuit Diagram and Datasheet
In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]
BQ24295 Smart Battery Charger IC with Boost + OTG
This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
BT169 SCR Datasheet [200 V, 0.5 A SCR]
The BT169 is a thyristor or SCR (Silicon Controlled Rectifier) that is commonly used for switching applications in low-power electronic circuits. It can be used for small signal, low current applications. Its size is very small just like a BJT. Here are the full technical specifications of the BT169: Electrical Specifications Pinout: The BT169 SCR […]
LM311 Datasheet, Circuit Applications
The LM311 is a versatile, fast voltage comparator with multiple capabilities. Its output stage is “open collector” and “open emitter,” allowing for various configurations. It can directly control relays and its output can be compatible with several logics, including TTL. Technical Specifications and Datasheet Here are some of the technical specifications of the LM311 comparator […]
