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 […]
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 […]
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 […]
