MIC4421 and MIC4422 MOSFET drivers are rugged, ef-ficient, 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 mar-gin.

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.

MIC4421/4422 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost.

Modern Bipolar/CMOS/DMOS construction guarantees freedom from latch-up. The rail-to-rail swing capability of CMOS/DMOS insures adequate gate voltage to the MOS-FET during power up/down sequencing.

Since these devices are fabricated on a self-aligned process, they have very low crossover current, run cool, use little power, and are easy to drive.
