General Description

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.

Features

• 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

• Independent supply pins for half-bridge applications

Applications

• Lamp drivers

• Motion Control

• Heater switching

• Power bus switching

• Half or full H-bridge drivers
