Overview

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 outputs in a programmable cascade sequence to enable the DC/DC converters.
The SMH4814 also monitors two independent –48V feeds.
The redundant power supplies allow for high availability and reliability...
