SMH4802 Programmable -48V Hot-Swap Controller

The SMH4802 is an integrated power controller for hot swappable add-in cards. The device operates from a wide supply range and generates the signals necessary to drive an isolated output DC/DC converter. As a typical add-in board is inserted into the powered backplane, physical connections must firs.
