CONTROL FUNCTIONS - PC PIN

Module Enable/Disable

Module Alarm

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.

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 4.

Primary Auxiliary Supply

At 5.7V, PC can source up to 1.5mA. In the example shown in

Figure 3, PC powers a module enabled LED.
