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.
