MIC4123/4124/4125

General Description

The MIC4123/4124/4125 family are highly reliable BiC-

MOS/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 driv-

ers 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-to-

rail 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-imped-

ance, 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.
