MIC4426/4427/4428
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.
