MIC4426/4427/4428

Dual 1.5A-Peak Low-Side MOSFET Driver

General Description

The MIC4426/4427/4428 family are highly-reliable dual low-

side MOSFET drivers fabricated on a BiCMOS/DMOS process

for low power consumption and high efﬁciency. These drivers

translate TTL or CMOS input logic levels to output voltage

levels that swing within 25mV of the positive supply or ground.

Comparable bipolar devices are capable of swinging only

to within 1V of the supply. The MIC4426/7/8 is available in

three conﬁgurations: dual inverting, dual noninverting, and

one inverting plus one noninverting output.

The MIC4426/4427/4428 are pin-compatible replacements

for the MIC426/427/428 and MIC1426/1427/1428 with im-

proved electrical performance and rugged design (Refer to

the Device Replacement lists on the following page). They

can withstand up to 500mA of reverse current (either polarity)

without latching and up to 5V noise spikes (either polarity)

on ground pins.

Primarily intended for driving power MOSFETs, MIC4426/7/8

drivers are suitable for driving other loads (capacitive, resistive,

or inductive) which require low-impedance, high peak current,

and fast switching time. Other applications include driving

heavily loaded clock lines, coaxial cables, or piezoelectric

transducers. The only load limitation is that total driver power

dissipation must not exceed the limits of the package.

Note See MIC4126/4127/4128 for high power and narrow

pulse applications.
