General Description

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.
