SMH4804 -48V Programmable Hot Swap Sequencing Power Controller – – www.DataSheet4U.com FEATURES AND APPLICATIONS INTRODUCTION The SMH4804 is a user-programmable -48V power supply controller designed to control the hot-swapping of plug-in cards and to sequence supplies in a distributed power environment. The SMH4804 drives an external power MOSFET switch that connects the bus side supply to the card side load and controls in-rush current while providing both current regulation and over-current protection. When the source and drain voltages of the external MOSFET are within specification, the SMH4804 asserts four PG[4:1]# power-good logic outputs either simultaneously or sequenced at programmable intervals to enable DC-DC converters to distribute card side power.
