General Description
The MAX5913A/MAX5914A are quadruple hot-swap con-
trollers. The MAX5913A/MAX5914A independently con-
trol four external n-channel switches to hot-swap system
loads from a single V
CC
supply line. The devices allow
the safe insertion and removal of power devices from live
network ports. The 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 MAX5913A/MAX5914A feature an internal under-
voltage lockout (UVLO) function that prevents the FET
from turning on, if V
CC
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 MAX5913A features an
active-low relay driver that sinks current when the relay
output is enabled. The MAX5914A 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
MAX5913A/MAX5914A use an external sense resistor
to enable all the internal current-sense functions.
The MAX5913A/MAX5914A 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 MAX5913A/MAX5914A are available in a 44-pin
MQFP package and are specified for the extended
-40癈 to +85癈 operating temperature range.
