General Description

The MIC4423/4424/4425 family are highly reliable

BiCMOS/DMOS buffer/driver/MOSFET drivers. They

are higher output 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

capable 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-impedance, 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.

See MIC4123/4124/4125 for high power and narrow

pulse applications.
