SMH4814 www.DataSheet4U.com Preliminary Information 1 (See Last Page) INTRODUCTION The SMH4814 is an integrated power controller designed to control the hot-swapping of plug-in cards in a distributed power environment.
The SMH4814 drives external power MOSFET switches that connect the supply to the load while reducing in-rush current and providing over-current protection.
When the source and drain voltages of the external MOSFETs are within specification the SMH4814 asserts the four PUP logic o
