A second comparator with a detection threshold of
3V
SC
activates a fast 15mA pulldown of the gate. The
purpose of this comparator is to rapidly discharge the
gate when a momentary current peak overstresses the
external FET, helping the regulation to act more rapidly.
The sense resistor is also used to detect an open-circuit
or low-current condition with a typical threshold of 3mV.
Open-Circuit Detection
The MAX5913A/MAX5914A detect when a port has low
current or is open circuit, and turn off the switch to that
port. After the switch is turned on and the POK condi-
tions are met, the open-circuit detector is enabled after
a 900ms delay. The open-circuit voltage threshold is set
at 3mV across the current-sense resistor. Drive OCEN
high to enable open-circuit detectors for all four ports.
Drive OCEN low to disable the detectors. Each port has
an open-circuit flag that can be read from STAT_ out-
puts when the STATOUT is low. STAT_ output high indi-
cates that the switch is latched off due to an
open-circuit condition on that port. To reset the latch
pull ON_ low and then high to restart (Table 1).
Output Voltage Sense and Power-OK
The MAX5913A/MAX5914A sense the output voltage of
the port at the source of the external MOSFET switch.
