MIC5010

Full-Featured High- or Low-Side MOSFET Driver

Not Recommended for New Designs

General Description

Features

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.

• 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

The MIC5010 charges a 1nF load in 60µs typical and

protects the MOSFET from over-current conditions. Faster

switching is achieved by adding two 1nF charge pump

capacitors. The current sense trip point is fully program-

mable and a dynamic threshold allows high in-rush current

loads to be started. A fault pin indicates when the MIC5010

has turned off the FET due to excessive current.

Applications

Other members of the Micrel driver family include the

MIC5011 minimum parts count 8 pin driver, MIC5012 dual

driver, and MIC5013 protected 8 pin driver.

• Lamp drivers

• Relay and solenoid drivers

• Heater switching

• Power bus switching

• Motion control

• Half or full H-bridge drivers
