Module Enable/Disable. The module may
be disabled by pulling PC below 2.3V with
respect to the –Input. This may be done
with an open collector transistor, relay, or
optocoupler. Multiple converters may be
disabled with a single transistor or relay
either directly or via “OR’ing” diodes.
See Figure 1.
Module Alarm.The module contains
“watchdog” circuitry which monitors input
voltage, operating temperature, and internal
operating parameters. In the event that any
of these parameters are outside of their
allowable operating range, the module will
shut down and PC will go low. PC will
periodically go high and the module will
check to see if the fault (as an example,
overtemperature) has cleared. If the fault
has not been cleared, PC will go low again
and the cycle will restart. The SC pin will
go low in the event of a fault and return to
its normal state after the fault has been
cleared. See Figures 2 and 3.
