Product Summary
The MIC4422YM is a 9A-peak low-side mosfet driver bipolar. The MIC4422YM is capable of 9A (peak)output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4422YM accepts any logic input from 2.4V to VS without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as 5V without damaging the part. Additional circuits protect against damage from electrostatic discharge. The MIC4422YM applications are: (1)Switch Mode Power Supplies; (2)Motor Controls; (3)Pulse Transformer Driver; (4)Class-D Switching Amplifiers; (5)Line Drivers; (6)Driving MOSFET or IGBT Parallel Chip Modules; (7)Local Power ON/OFF Switch; (8)Pulse Generators.
