General Description

The MIC4126, MIC4127, and MIC4128 family are

highly-reliable dual 1.5A low-side MOSFET drivers

fabricated on Microchip’s BiCMOS/DMOS process.

The devices feature low power consumption and high

efficiency. The MIC4126/27/28 translate TTL or CMOS

input logic levels to output voltage levels that swing

within 25mV of the positive supply or ground whereas

comparable bipolar devices are capable of swinging

only to within 1V of the supply. The MIC4126/7/8 is

available in three configurations: dual inverting, dual

noninverting, and complimentary output.

The MIC4126/27/28 offer pin-compatible as well as

smaller footprint replacements for the MIC4426/27/28

with improved packaging and electrical performance.

The MIC4126/27/28 are available in exposed pad,

EPAD, SOIC-8L and MSOP-8L options as well as a

small-size VDFN ML?-8L option. The devices have an

input operating range of 4.5V to 20V.

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. The devices can withstand up to 500mA of

reverse current (either polarity) without latching and up

to 5V noise spikes (either polarity) on ground pins.
