MIC4422 Datasheet – MOSFET Driver – Micrel

Part Number: MIC4422, MIC4421

Function: 9A-Peak Low-Side MOSFET Driver

Package: SOP 8, DIP 8 Pin Type

Manufacturer: Micrel Semicondcutor


MIC4422 datasheet



MIC4421 and MIC4422 MOSFET drivers are rugged, efficient, and easy to use. The MIC4421 is an inverting driver, while the MIC4422 is a non-inverting driver.



Both versions are capable of 9A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421/4422 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.
