MAX5914

MAX5913/MAX5914 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. The devices also feature a +12V relay driver with 100mA current drive capable of driving low-voltage +3.3V relays. The MAX5913 features an active-low relay driver that sinks current when the relay output is enabled. The MAX5914 features an active-high relay driver...
