MIC4123/4124/4125 Micrel, Inc. MIC4123/4124/4125
Dual 3A-Peak Low-Side MOSFET Driver
Bipolar/CMOS/DMOS Process General Description Features The MIC4123/4124/4125 family are highly reliable BiCMOS/DMOS buffer/driver/MOSFET drivers. They are higher
output current versions of the MIC4126/4127/4128, which
are improved versions of the MIC4426/4427/4428. All three
families are pin-compatible. The MIC4123/4124/4125 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 MIC4123/4124/4125 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-torail voltage swings. Primarily intended for driving power MOSFETs, the
MIC4123/4124/4125 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. Reliable, low-power bipolar/CMOS/DMOS construction
