General Description
The MIC5013 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 1nF 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.
Typical Application
Note: The MIC5013 is ESD sensitive.
