I am new to Power Electronics, I am working on to AC line detection using H11AA1 IC. Schematic is as shown here
. With the following calculation, I figured out the resistor value R1=8K R1= ( Vs - V_led)/(10mA) which is in my case R1=( 230 - 1.5)/(10mA) =22.8K; So I added R1 20 K/1Watt but I could not achieve the result; Has anyone work with H11AA1 IC for the similar purpose, Do I need to change R1 value?? DataSheet of H11AA1 here vishay.com/docs/83608/h11aa1.pdf
