MIC4421 and MIC4422 MOSFET gate 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 9 A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421/4422 accepts any logic input from 2.4 V to VS without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as -5 V without damaging the part. Additional circuits protect against damage from electrostatic discharge.
MIC4421/4422 gate 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.
