MIC5031

High-Speed High-Side MOSFET Driver

Not Recommended for New Designs

General Description

Features

The MIC5031 MOSFET driver is designed to switch an

N-channel enhancement-type MOSFET from a TTL control

signal in a high-side switch application. The MIC5031 pro-

vides overcurrent protection, can accommodate loads with

high-inrush current, and is designed to survive automotive

power disturbances. This driver is suitable for up to 30kHz

PWM operation with 0% to 100% duty cycle.

• +4.5V to +30V operation

• Fast gate drive

(rise time = 70ns, fall time = 50ns,

with 1000pF load and 5V supply)

• Overcurrent detection across MOSFET

• Overcurrent shutdown delay

• Charge pump for high-side dc applications

• TTL compatible input

• Overtemperature shutdown

• Automotive load dump protection

• Reverse battery protection

• Open-collector fault flag

The MIC5031 is powered by the +4.5V to +30V load voltage.

An external bootstrap capacitor and internal charge pump

drive the gate output higher than the supply voltage. The

bootstrap capacitor provides speed, while the charge pump

can sustain the high gate output voltage continuously.

• Near zero-current disable state

The MIC5031 features a resistor programmable overcurrent

shutdown (circuit breaker) function that monitors the voltage

drop across the external MOSFET. A capacitor program-

energized without causing undesired shutdown. An open-

load detection feature is included and can be used by adding

an external high-value resistor.

Applications

• Automotive power switch

• Automotive PWM control

• Circuit breaker

• PWM circuits

excessive power dissipation by an internal overtemperature

shutdown circuit.
