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 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.

•

Reliable, low-power bipolar/CMOS/DMOS construction

Latch-up protected to >200mA reverse current

Logic input withstands swing to –5V

High 3A-peak output current

Wide 4.5V to 20V operating range

Drives 1800pF capacitance in 25ns

Short <50ns typical delay time

Delay times consistent with in supply voltage change

Matched rise and fall times

TTL logic input independent of supply voltage

Low equivalent 6pF input capacitance

Low supply current

3.5mA with logic-1 input

350µA with logic-0 input

TheMIC4123/4124/4125seriesdriversareeasiertouse,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.

•

Low 2.3Ω typical output impedance

Output voltage swings within 25mV of ground or V_S.

Primarily intended for driving power MOSFETs, the

MIC4123/4124/4125driversaresuitablefordrivingotherloads

(capacitive, resistive, or inductive) which require low-imped-

ance, high peak currents, and fast switching times. Heavily

loadedclocklines,coaxialcables,orpiezoelectrictransducers

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.
