Product Descriptions

The MIC4451 and MIC4452 CMOS MOSFET drivers are robust, efficient, and easy to use. The MIC4451 is an inverting driver, while the MIC4452 is a non-inverting driver. Both versions are capable of 12A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4451/52 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.

MIC4451/52 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost.

Modern Bipolar/CMOS/DMOS construction ensures freedom from latch-up. The rail-to-rail swing capability of CMOS/DMOS ensures adequate gate voltage to the MOSFET during power up/down sequencing. Because 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.
