General Description
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 provides 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.

Features
• +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
• Near zero-current disable state

Applications
• Automotive power switch
• Automotive PWM control
• Circuit breaker
• PWM circuits
