Microchip Technology, Inc. Gate Drivers MIC4420BM

The MIC4420BM is a low-side MOSFET driver capable of delivering a peak output current of 6A. It features a CMOS construction that ensures latch-up protection, allowing it to withstand reverse output currents greater than 500 mA. The driver operates within a supply voltage range of 4.5V to 18V and can handle high capacitive loads up to 10,000 pF. It has matched rise and fall times of 25 ns and a low delay time of 55 ns, making it suitable for fast switching applications. The MIC4420BM accepts logic inputs from 2.4V to the supply voltage without the need for external speed-up capacitors or resistor networks. It can withstand negative input swings of up to 5V, enhancing its robustness in various applications. The device is designed for use in switch mode power supplies, motor controls, pulse transformer drivers, and Class-D switching amplifiers. It is available in multiple package types, including 8-lead PDIP, 8-lead SOIC, and 5-lead TO-220, providing flexibility for different design requirements.
