In cars or automobiles, LEDs have grown to be the preferred choice of lighting. Whether it’s the rear tail-lights or the tell-tale indicators in the cluster as indicated in Figure 1 below, all incorporate LEDs nowadays. Their compact dimensions helps versatility in design and offers the prospective to be as durable as the vehicle’s life […]

Automotive Display LED-backlight Driver Circuit using LP8864-Q1
The LP8864-Q1 is this cool automotive high-efficiency LED driver that comes with a boost controller. Basically it is made to efficiently power the LEDs in your car. It has got these four high-precision current sinks that do something called phase shifting. What is neat is that this phase shifting automatically adjusts based on how many […]
Simplest Piezo Driver Circuit Explained
In the previous post I explained a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. As discussed earlier a piezo transducer basically requires a frequency to vibrate and reproduce the required sound. […]
L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
2 Simple MOSFET Gate Driver Circuits using BJTs
Very often we see that output coming from a microcontroller, oscillator, comparator, or PWM stage is just not strong enough for driving a power MOSFET directly, it gives signal, yes, but gate does not respond properly unless some decent current reaches there. A MOSFET gate behaves like a small capacitor, so now unless that gate […]
A4988 Motor Driver Circuit Diagram with IC 555
In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]
