SUPERVISORY CIRCUIT OPERATION
The system power ON/OFF logic is generated by
the PC, which is “Low” in system “On” condition
and “High” when the system is “Off”. This is con-
nected to remote pin 7.
The IC’s internal logic circuit generates a control
signal on pin 6. In normal operation, when there is
no over voltage or over current at the three inputs,
the voltage on pin 6 follows the Remote pin 7 volt-
age, i.e. if the remote pin 7 is low the pin 6 is also
low or vice versa.
When fault is detected on the inputs, control pin 6
goes “High”. This control pin 6 output can be used
to turn off the Mains Power Supply during fault
condition. An optocoupler is connected directly,

with cathode connected to the IC pin 6 and anode
to 5V (from STDBY supply).
In normal operation the voltage on pin 6 is (opto
cathode) is around 3.7 V. On the primary side the
opto transistor collector is pulled through a resistor
to Vref.
It is required to invert the signal before connecting
to the feedback compensation pin 6 of L5991A for
reverse logic. i.e during normal operation the com-
pensation pin is not affected and during fault con-
dition the pin is pulled Low. Slight delay (R34,C32)
is introduced on the primary side to avoid fault turn
on condition.
Note : Once the fault condition is removed, it is required to reset the
Remote pin to make the system function again.
