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, ef-

ﬁcient, 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.

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

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

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

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

• Output Voltage Swing to Within 25mV of GND or V_S

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

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.

MIC4421/4422 drivers can replace three or more discrete

components, reducing PCB area requirements, simplifying

product design, and reducing assembly cost.

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

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 MOS-

FET 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.
