General Description
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 supply rail in high-side power switch applications. The 8-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.

Features
• 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
• Implements high- or low-side drivers

Applications
• Lamp drivers
• Relay and solenoid drivers
• Heater switching
• Power bus switching
