MIC5011集成电路（IC）的栅极驱动器规格书PDF中文资料

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.

特性 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
