MIC4421A/22A

9A Peak Low-Side MOSFET Drivers

Features

General Description

• High Output Current: 9A Peak (Typical)

• Wide Operating Range: 4.5V to 18V (Typical)

• Minimum Pulse Width: 50 ns

The 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.

• Latch-Up Proof: Fully Isolated Process is

Inherently Immune to Any Latch-Up

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.

• Input Will Withstand Negative Swing of Up to 5V

• High Capacitive Load Drive: 47,000 pF

• Low Delay Time: 15 ns (Typical)

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

• Low Equivalent Input Capacitance: 7 pF (typical)

• Low Supply Current: 500 µA (Typical)

MIC4421A/22A drivers can replace three or more

Applications

Modern

Bipolar/CMOS/DMOS

construction

• Switch Mode Power Supplies

• Motor Controls

guarantees freedom from latch-up. The rail-to-rail

swing capability of CMOS/DMOS ensures adequate

gate voltage to the MOSFET during power up/down

sequencing. Because 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.

• Pulse Transformer Driver

• Class-D Switching Amplifiers

• Line Drivers

• Driving MOSFET or IGBT Parallel Chip Modules

• Local Power On/Off Switch

• Pulse Generators
