Half-Bridge with Ultra-Precise Current Sense Feedback for Solenoid

A Half-bridge converter is widely used in applications such as DC-DC converters, switch mode power supplies, inverters, motor drivers, resistive loads, and solenoid drivers. This project consists of an IR2104 Half-bridge driver chip, 2 x DPAK MOSFETS, and an INA293 precision current sense amplifier. The IR2104 is a half-bridge, high voltage, high-speed power MOSFET and IGBT driver with dependent high and low side referenced output channels. It drives high and low-side N-channel MOSFETs, INA293 chip measures the load current across the shunt resistor connected to the output.
