Microchip | MIC5013YN

The MIC5013YN is an 8-pin MOSFET driver with over-current shutdown and a fault flag. It is designed to drive the gate of an N-channel power MOSFET above the supply rail high-side power switch applications. The MIC5013 is compatible with standard or current-sensing power MOSFETs in both high- and low-side driver topologies.

The MIC5013 charges a 1 nF load in 60µs typical and protects the MOSFET from over-current conditions. The current sense trip point is fully programmable and a dynamic threshold allows high in-rush current loads to be started. A fault pin indicates when the MIC5013 has turned off the FET due to excessive current. Other members of the Micrel driver family include the MIC5011 minimum parts count driver and MIC5012 dual driver.

Key Features:

• 7 V to 32 V operation.
• Less than 1 µA standby current in the “OFF” state.
• 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.
• 60 µs typical turn-on time to 50% gate overdrive.
• Programmable over-current sensing.
• Dynamic current threshold for high in-rush loads
• Fault output pin indicates current faults.
• Implements high- or low-side switches.

Applications:

• Lamp drivers.
• Relay and solenoid drivers.
