MIC4451/4452

12A-Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS Process

General Description

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 MIC4451/4452 accepts any logic

input from 2.4V to V

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.

MIC4451/4452 drivers can replace three or more discrete

components, reducing PCB area requirements, simplifying

product design, and reducing assembly cost.

Modern Bipolar/CMOS/DMOS construction guarantees

freedom from latch-up. The rail-to-rail swing capability of

CMOS/DMOS insures adequate gate voltage to the

MOSFET during power up/down sequencing. Since 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.
