MAX5911 - -48V Simple Swapper Hot-Swap Switches

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.

Features

  • that prevent damage to the internal FET. They include an enable input, which responds to positive logic signals (+3.3V or +5V), allowing the host system to disconnect the load. ENABLE is also used to reset the device after a latching fault condition occurs. The MAX5911/MAX5912 Simple Swapper™ hot-swap ICs monitor four parameters for these fault conditions: undervoltage lockout (UVLO), power-not-good, zerocurrent detection, and thermal shutdown. These devices are available in the extended tempera.

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.
