Device Overview

Summary

MIC4120 and MIC4129 MOSFET drivers are tough, efficient, and easy to use. The MIC4129 is an inverting driver, while the MIC4120 is a non-inverting driver. The MIC4120 and MIC4129 are improved versions of the MIC4420 and MIC4429. They are capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4120/4129 accept 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. MIC4120/4129 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 insures adequate gate voltage to the MOSFET during power up/down sequencing.
