I want to use HCPL3700 optocoupler for sensing 220V (line). I design a circuit but I want to ask some questions.
HCPL3700 is an open-collector output so I pull-up Vout. In AC voltage sensing some people says HCPL3700 is halted on zero-cross so I add a cap (C30) is this (10uF) enough for zero-cross pulse filtering?
I add a resistor (R29) (100k) to the input of HCPL3700 for 200V threshold is this ok?
