Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 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 VCC 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. If the switch remains in current limit for more than a programmable time, the N-channel FET latches off and the supply can be restarted either by autoretry or by an external command after the preset off-time has elapsed.

The MAX5913/MAX5914 are available in a 44-pin MQFP package and are specified for the extended -40°C to +85°C operating temperature range.
