MIC4420, MIC4429 and MIC429 MOSFET drivers are tough, efficient, and easy to use. The MIC4429 and MIC429 are inverting drivers, while the MIC4420CM is a non-inverting driver.They are capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4420/4429/429 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.MIC4420/4429/429 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost.Modern BiCMOS/DMOS construction guarantees freedom from latch-up. The rail-to-rail swing capability helps ensure adequate gate voltage to the MOSFET during power up/down sequencing.Note: See MIC4120/4129 for high power and narrow pulse applications.
