MIC5011

Minimum Parts High- or Low-Side MOSFET Driver

General Description

Features

The MIC5011 is the “minimum parts count” member of the

Micrel MIC501X driver family. These ICs are designed to

drive the gate of an N-channel power MOSFET above the

supplyrailinhigh-sidepowerswitchapplications. The8-pin

MIC5011 is extremely easy to use, requiring only a power

FET and nominal supply decoupling to implement either a

high- or low-side switch.

• 4.75V 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

• Minimum external parts count

• Can be used to boost drive to low-side power FETs

operating on logic supplies

• 25µs typical turn-on time with optional external

capacitors

The MIC5011 charges a 1nF load in 60µs typical with no

external components. Faster switching is achieved by add-

ing two 1nF charge pump capacitors. Operation down to

4.75V allows the MIC5011 to drive standard MOSFETs in

5V low-side applications by boosting the gate voltage

above the logic supply. In addition, multiple paralleled

MOSFETs can be driven by a single MIC5011 for ultra-high

current applications.

• Implements high- or low-side drivers

Applications

• Lamp drivers

Other members of the Micrel driver family include the

MIC5012 dual driver and MIC5013 protected 8-pin driver.

• Relay and solenoid drivers

• Heater switching

• Power bus switching

For new designs, Micrel recommends the pin-compatible

MIC5014 MOSFET driver.
