MAX5913 - +48V Quad Hot-Swap Controllers

General Description

The MAX5913/MAX5914 are quadruple hot-swap controllers.

The MAX5913/MAX5914 independently control four external N-channel switches to hot-swap system loads from a single VCC supply line.

The devices allow the safe insertion and removal of power devices from live network ports.

Key Features

  • an active-low relay driver that sinks current when the relay output is enabled. The MAX5914 features an active-high relay driver output that sources 1mA to drive an external FET relay driver when the relay output is enabled. Control circuitry ensures the relays and the FETs are off until V CC reaches the UVLO threshold. The MAX5913/ MAX5914 use an external sense resistor to enable all the internal current-sense functions. The MAX5913/MAX5914 feature a programmable analog current-limit circuit. I.

19-2244; Rev 2; 11/02 +48V Quad Hot-Swap Controllers For Power-Over-LAN General Description The MAX5913/MAX5914 are quadruple hot-swap controllers. The MAX5913/MAX5914 independently control four external N-channel switches to hot-swap system loads from a single VCC supply line. The devices allow the safe insertion and removal of power devices from live network ports. Operating supply voltage range is between +35V and +72V. The devices are intended for applications in Power-Over-Media-Dependent Interface (MDI), but are not limited to such usage. The MAX5913/MAX5914 feature an internal undervoltage lockout (UVLO) function that prevents the FET from turning on, if VCC does not exceed the default value of +32V.
