MIC4421/4422

9A-Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS Process

General Description

Features

• BiCMOS/DMOS Construction

• Latch-Up Proof: Fully Isolated Process is Inherently

Immune to Any Latch-up.

MIC4421 and MIC4422 MOSFET drivers are rugged, effi-

cient, and easy to use. The MIC4421 is an inverting driver,

while the MIC4422 is a non-inverting driver.

• Input Will Withstand Negative Swing of Up to 5V

• Matched Rise and Fall Times............................... 25ns

• High Peak Output Current .............................. 9A Peak

• Wide Operating Range.............................. 4.5V to 18V

• High Capacitive Load Drive...........................47,000pF

• Low Delay Time ........................................... 30ns Typ.

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

the largest MOSFETs with an improved safe operating mar-

gin. The MIC4421/4422 accepts any logic input from 2.4V to

without external speed-up capacitors or resistor net-

works. 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.

• Logic High Input for Any Voltage from 2.4V to V

• Low Equivalent Input Capacitance (typ).................7pF

• Low Supply Current..............450µA With Logic 1 Input

• Low Output Impedance ........................................ 1.5Ω

MIC4421/4422 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

Modern Bipolar/CMOS/DMOS construction guarantees free-

dom from latch-up. The rail-to-rail swing capability of CMOS/

DMOS insures adequate gate voltage to the MOSFET dur-

ing 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
