The DW01A chip is a battery protection device for a single cell Lithium Ion battery. It protects the cell from over and under charging, reverse connection and short circuit. You can typically find this chip on TP4056 breakout boards (Lithium…
LM35 is a precision integrated circuit temperature sensor that can measure temperature with an accuracy of ±0.5°C at a range of -55°C to 150°C. It was developed by National Semiconductor Corporation, now a part of Texas Instruments, and has become…
Introduction Although using a NTC can make your temperature measurement very easy. But for industrial purpose you can use a thermocouple for better stability and wider range. Thermocouple Thermocouple consists of two different conductors forming an electrical junction at different…
We all know that we can simply drive a relay with the help of transistor. But this method is not isolated. In many places we may require an isolation between the relay and the driving section. In those places…
A voltage buffer, also known as a voltage follower, or a unity gain amplifier, is an amplifier with a gain of 1. It’s one of the simplest possible op-amp circuits with closed-loop feedback. Even though a gain of 1 doesn’t…
In many cases we require to drive high current output but at a cost effective manner. Either we use a high current transistor or a discrete Darlington pair to drive high current load. But the common way is to use…
As a designer the number of available ports on a microcontroller are always less while designing an embedded circuit. To get more out of a single controller chip we need to have an I/O expender, so that we can use…
74HC595 The 74HC595 is a high speed 8-BIT SHIFT REGISTERS with OUTPUT LATCHES (3-STATE) fabricated with silicon gate CMOS technology. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has…
