19-1832; Rev 0a; 1/01 -48V Simple Swapper Hot-Swap Switches General Description The MAX5911/MAX5912 are fully integrated hot-swap switches for negative supply rails.
These devices allow the safe insertion and removal of circuit cards into live backplanes or ports without causing problematic glitches on the negative power-supply rail.
They also monitor various circuit parameters and disconnect the load if a fault condition occurs, alerting the host with a logic-level FAULT output.
The MAX5911/MAX5912 operate over a voltage range of -16V to -65V and are designed to permit hot plugging of an IP phone into a hub, but are not limited to that operation.
During startup, an internal power FET regul...
