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.
