MIC4423/4424/4425

Dual 3A-Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS Process

General Description

The MIC4423/4424/4425 family are highly reliable BiCMOS/

DMOS buffer/driver/MOSFET drivers. They are higher out-

put current versions of the MIC4426/4427/4428, which are

improved versions of the MIC426/427/428. All three families

are pin-compatible. The MIC4423/4424/4425 drivers are ca-

pable of giving reliable service in more demanding electrical

environments than their predecessors. They will not latch

under any conditions within their power and voltage ratings.

They can survive up to 5V of noise spiking, of either polarity,

on the ground pin. They can accept, without either damage

or logic upset, up to half an amp of reverse current (either

polarity) forced back into their outputs.

The MIC4423/4424/4425 series drivers are easier to use, more

ﬂexible in operation, and more forgiving than other CMOS

or bipolar drivers currently available. Their BiCMOS/DMOS

construction dissipates minimum power and provides rail-to-

rail voltage swings.

Primarily intended for driving power MOSFETs, the

MIC4423/4424/4425 drivers are suitable for driving other loads

(capacitive, resistive, or inductive) which require low-imped-

ance, high peak currents, and fast switching times. Heavily

loaded clock lines, coaxial cables, or piezoelectric transducers

are some examples. The only known limitation on loading is

that total power dissipated in the driver must be kept within

the maximum power dissipation limits of the package.

Note: See MIC4123/4124/4125 for high power and narrow

pulse applications.
