The Microchip MIC5021 is a high-speed, high-side MOSFET driver designed to operate at frequencies up to 100 kHz, making it ideal for applications such as motor control, switch-mode power supplies (SMPS), and solenoid switching. Operating within a voltage range of 12V to 36V, this driver features a rapid 550 ns rise/fall time when driving a 2000 pF load, ensuring efficient performance in high-speed applications. The MIC5021 includes an internal charge pump, gate-to-source protection, and an overcurrent limit with a 50 mV trip voltage, making it compatible with current-sensing MOSFETs. Additional features include a TTL-compatible input with an internal pull-down resistor, a current-source drive to reduce EMI, and the capability to function as a circuit breaker with or without automatic retry. Available in 8-pin SOIC and plastic DIP packages, the MIC5021 is a versatile and robust solution for controlling high-side MOSFETs in demanding electronic applications.
