The TC4421VAT is a monolithic MOSFET driver from Microchip. It is used to control a single MOSFET with up to 10A peak output current in various switching configurations, such as on/off, PWM, and pulse-width modulation (PWM). The device offers 600V source-drain voltage with a 0.21O on-resistance and fast switching times of 3.2ns rise/fall. It is designed for use in automotive, industrial, and consumer applications where low power dissipation and high efficiency are required. Additionally, the device features over-temperature and short-circuit protection, ESD protection, and under-voltage lockout (UVLO).
