MICREL MIC4422BM MOSFET Driver LO-SIDE 9 Amp Output Non-Inverting 9A-Peak / SMD SOIC-8
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 V S 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.

Proprietary circuits allow the input to swing negative by as

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 MOSFET
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.
