MIC4126/27/28

Dual 1.5A-Peak Low-Side MOSFET

Drivers in Advanced Packaging

General Description

Features

The MIC4126, MIC4127, and MIC4128 family are highly-

reliable dual 1.5A low-side MOSFET drivers fabricated on

Micrel’s BiCMOS/DMOS process. The devices feature low

• Dual 1.5A-peak drivers

• 4.5V to 20V operating range

• Exposed backside pad packaging reduces heat

– ePAD SOIC-8L (θ_JA= 58°C/W)

power

consumption

and

high

efficiency.

The

MIC4126/27/28 translate TTL or CMOS input logic levels to

output voltage levels that swing within 25mV of the positive

supply or ground whereas comparable bipolar devices are

capable of swinging only to within 1V of the supply. The

MIC4126/7/8 is available in three configurations: dual

inverting, dual non-inverting, and complimentary output.

– ePAD MSOP-8L (θ_JA= 60°C/W)

– 3mm x 3mm MLF™-8L (θ_JA= 60°C/W)

• Bipolar/CMOS/DMOS construction

– 25mV maximum output offset from supply or ground

• Latch-up protection to >200mA reverse current

• Switches 1000pF in 25ns

• Logic-input threshold independent of supply voltage

• Logic-input protection to –5V

• 6pF typical equivalent input capacitance

The MIC4126/27/28 offer pin-compatible as well as smaller

footprint replacements for the MIC4426/27/28 with

improved packaging and electrical performance. The

MIC4126/27/28 are available in exposed pad, EPAD,

SOIC-8L and MSOP-8L options as well as a small-size

3mm x 3mm MLF™-8L option. The devices have an input

operating range of 4.5V to 20V.

• Dual inverting, dual non-inverting, and complementary

configurations

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. The

devices can withstand up to 500mA of reverse current

(either polarity) without latching and up to 5V noise spikes

(either polarity) on ground pins.

• -40°C to +125°C operating junction temperature range

Applications

• DC/DC converters

• Motor drivers

• Clock line driver
