IRPLHALO1E
above maximum load with a delay of approximately 0.5s. This is based on a current waveform that
has a sinusoidal envelope with a high frequency square wave component with 50% duty cycle.
Both shutdown modes have auto reset, which allows the oscillator to start again approximately 1s
after shutting down. This is so that if the fault condition is removed the system can start operating
normally again without the line voltage having to be switched off and back on again. It also provides
a good indication of overload to the end user as all the lamps connected to the system will flash on
and off continuously if too many are connected.
The shut down circuit also uses the external CSD capacitor for it’s timing functions. When the 0.5V
threshold is exceeded at CS the CSD is internally disconnected from the voltage compensation
circuit and connected to the shutdown circuit. The oscillator operates at minimum frequency when
the CSD capacitor is required for shutdown circuit timing. When the 0.5V threshold is exceeded the
IR2161 charges CSD rapidly to 4V.
When the shutdown threshold of 0.5V is exceeded the CSD capacitor is charged by current source
I_OL and when the threshold of 1.2V is exceeded it is charged by I_SD as well. If 1.2V is exceeded
CSD will charge from 4V to 12V in approximately 50ms. When 0.5V is exceeded but 1.0V is not,
CSD charges from 4V to 12V in approximately 0.5s. The timing accounts for the fact that high
frequency pulses with approximately 50% duty cycle and a sinusoidal envelope appear at the CS
pin. The values of I_SD and I_OL take into account that only at the peak of the mains will the
comparator outputs go high and effectively the capacitor will be charged in steps each line half
cycle.
If a fault is detected but disappears before CSD reaches 12V then CSD will discharge to 2.5V and
then the system will revert to compensation mode without interruption of the output.
Similarly when the system starts up again after a delay the CSD capacitor will be internally switched
back to the voltage compensation circuit. If the fault is still present the system will immediately
switch CSD back to the shutdown circuit.
