MIC5013

Protected High- or Low-Side MOSFET Driver

General Description

Features

The MIC5013 is an 8-pin MOSFET driver with over-current

shutdown and a fault flag. It is designed to drive the gate of

anN-channelpowerMOSFETabovethesupplyrailhigh-side

power switch applications. The MIC5013 is compatible with

standard or current-sensing power MOSFETs in both high-

and low-side driver topologies.

• 7V to 32V operation

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

• Available in small outline SOIC packages

• Internal charge pump to drive the gate of an N-channel

power FET above supply

• Internal zener clamp for gate protection

• 60µs 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

theMOSFETfromover-currentconditions.Thecurrentsense

trip point is fully programmable and a dynamic threshold

allows high in-rush current loads to be started. A fault pin

indicates when the MIC5013 has turned off the FET due to

excessive current.
