MIC4451/52

12A Peak Low-Side MOSFET Drivers

Features

General Description

• BiCMOS/DMOS Construction

The MIC4451 and MIC4452 CMOS MOSFET drivers

are robust, efficient, and easy to use. The MIC4451 is

• Latch-Up Proof: Fully Isolated Process is

Inherently Immune to Any Latch-Up

an inverting driver, while the MIC4452 is

non-inverting driver.

• Input Will Withstand Negative Swing of up to 5V

• Matched Rise and Fall Times: 25 ns

• High Peak Output Current: 12A

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

can drive the largest MOSFETs with an improved safe

operating margin. The MIC4451/52 accept 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.

• Wide Operating Range: 4.5V to 18V

• High Capacitive Load Drive: 62,000 pF

• Low Delay Time: 30 ns (typ.)

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

• Low Supply Current 450 µA with Logic 1 Input

• Low Output Impedance: 1.0Ω

MIC4451/52 drivers can replace three or more discrete

components, reducing PCB area requirements,

simplifying product design, and reducing assembly

cost.

• Output Voltage Swing to within 25 mV of GND or

V_S

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

Modern Bipolar/CMOS/DMOS construction ensures

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.

Applications

• Switch Mode Power Supplies

• Motor Controls

• Pulse Transformer Driver

• Class-D Switching Amplifier

• Line Drivers

• Driving MOSFET or IGBT Parallel Chip Modules

• Local Power ON/OFF Switch

• Pulse Generators
