The TC4423EPA is a dual MOSFET driver designed by Microchip. It is designed to drive two N-channel MOSFETs in a half-bridge configuration and can be used in applications such as motor control, power supplies, and pulse-width modulation (PWM) circuits. The TC4423EPA has a single-ended input and is compatible with both TTL and CMOS inputs. It has an adjustable output current up to 5 amps and can withstand up to 40 volts at the outputs. It also includes built-in under-voltage shutdown, thermal shutdown, and over-current protection.
