MAX5913EMH
+48V Quad Hot-Swap Controllers For Power-Over-LAN
General DescriptionThe MAX5913/MAX5914 are quadruple hot-swap con-
trollers. The MAX5913/MAX5914 independently control
four external N-channel switches to hot-swap system
loads from a single VCCsupply 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 undervolt-
age lockout (UVLO) function that prevents the FET from
turning on, if VCCdoes 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
VCCreaches 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 ana-
log 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.

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
