General Description

The MIC5010 is the full-featured member of the Micrel MIC501X driver family. These ICs are designed to drive the gate of an N-channel power MOSFET above the supply rail in high-side power switch applications. The MIC5010 is compatible with standard or current-sensing power FETs in both high- and low-side driver topologies.

Features

• 7V to 32V operation

• Less than 1µA standby current in the “OFF” state

• Internal charge pump to drive the gate of an N-channel power FET above supply

• Available in small outline SOIC packages

• Internal zener clamp for gate protection

• 25µs typical turn-on time to 50 gate overdrive

• Programmable over-current sensing

• Dynamic current threshold for high in-rush loads

• Fault output pin indicates current faults

• Implements high- or low-side switches

Applications

• Lamp drivers

• Relay and solenoid drivers

• Heater switching

• Power bus switching

• Motion control

• Half or full H-bridge drivers
