What is the maximum current allow through the open collector PG pin? Nothing is stated in the datasheet. It looks like 100uA has been used for curves and examples.
The sinking current Ipg is related to the logic voltage level of Vpg. The curve of Ipg vs Vpg is:
For example, if the logic low level of PG is 0.5V, the PG current is about 1.1mA.
