MIC4451/4452

12A-Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS Process

General Description

Features

MIC4451 and MIC4452 CMOS MOSFET drivers are

tough, efficient, and easy to use. The MIC4451 is an

inverting driver, while the MIC4452 is a non-inverting

driver.

• BiCMOS/DMOS Construction

• Latch-Up Proof: Fully Isolated Process is Inherently

Immune to Any Latch-up.

• Input Will Withstand Negative Swing of Up to 5V

• Matched Rise and Fall Times: 25ns

•..High Peak Output Current: 12A Peak

•..Wide Operating Range: 4.5V to 18V

•..High Capacitive Load Drive: 62,000Pf

•..Low Delay Time: 30ns (typ)

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

•..Low Supply Current450µA With Logic 1 Input

•..Low Output Impedance: 1.0Ω

Both versions are capable of 12A (peak) output and can

drive the largest MOSFETs with an improved safe

operating margin. The MIC4451/4452 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.

MIC4451/4452 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

• Low Equivalent Input Capacitance (typ): 7pF

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.
