MIC5012

Dual High- or Low-Side MOSFET Driver

Not Recommended for New Designs

General Description

Features

The MIC5012 is the dual 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 14-pin MIC5012 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

• 2 independent drivers; implements high and low side

drivers

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

channel

• 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

• Minimum external parts count

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

operating on logic supplies

TheMIC5012chargesa1nFloadin60µstypical. Operation

down to 4.75V allows the MIC5012 to drive standard

MOSFETs in 5V low-side applications by boosting the gate

voltage above the logic supply. In addition, multiple, paral-

leledMOSFETscanbedrivenbyasingleMIC5012forultra-

high current applications.

• Independent supply pins for half-bridge applications

Other members of the Micrel driver family include the

MIC5010full-featureddriver,MIC5011minimumpartscount

driver, and MIC5013 protected 8-pin driver.

Applications

• Lamp drivers

• Motion Control

• Heater switching

• Power bus switching

• Half or full H-bridge drivers

For new designs, Micrel recommends the pin-compatible

MIC5016 dual MOSFET driver.
