MIC4421A/4422A

9A Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS Process

General Description

Features

MIC4421A and MIC4422A MOSFET drivers are rugged,

efficient, and easy to use. The MIC4421A is an inverting

driver, while the MIC4422A is a non-inverting driver.

• High peak-output current: 9A Peak (typ.)

• Wide operating range: 4.5V to 18V (typ.)

• Minimum pulse width: 50ns

Both versions are capable of 9A (peak) output and can

drive the largest MOSFETs with an improved safe

operating margin. The MIC4421A/4422A accepts any logic

input from 2.4V to V_Swithout external speed-up capacitors

or resistor networks. Proprietary circuits allow the input to

swing negative by as much as 5V without damaging the

part. Additional circuits protect against damage from

electrostatic discharge.

• Latch-up proof: fully isolated process is inherently

immune to any latch-up

• Input will withstand negative swing of up to 5V

• High capacitive load drive: 47,000pF

• Low delay time: 15ns (typ.)

• Logic high input for any voltage from 2.4V to V_S

• Low equivalent input capacitance: 7pF (typ.)

• Low supply current: 500µA (typ.)

MIC4421A/4422A drivers can replace three or more

discrete components, reducing PCB area requirements,

simplifying product design, and reducing assembly cost.

• Output voltage swing to within 25mV of GND or V_S

Modern Bipolar/CMOS/DMOS construction guarantees

freedom from latch-up. The rail-to-rail swing capability of

CMOS/DMOS insures adequate gate voltage to the

MOSFET during power up/down sequencing. Since these

devices are fabricated on a self-aligned process, they have

very low crossover current, run cool, use little power, and

are easy to drive.

Applications

• Switch mode power supplies

• Motor controls

• Pulse transformer driver

• Class-D switching amplifiers

• Line drivers

• Driving MOSFET or IGBT parallel chip modules

• Local power ON/OFF switch

• Pulse generators
