Microchip | MIC4120YME

MIC4120YME 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 6 A (peak) output and can drive the largest MOSFETs with an improved safe operating margin.

The MIC4120/4129 accept 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. 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.
