Just saying “MCU” doesn’t tell me what it is for. Ok H11AA seems to work on 1mA. Sign up using Facebook. This opto-coupler will work fine at 1 mA AC.
Take a look at an IL if you want to know what the line voltage is as the current in the two output diodes is well matched. I am also not able to use a x-capacitor or use a transformer due to size constraints. Or do you just want to know that AC of at least a certain rms voltage is there?
Sparky 11k 2 15 Also H11AA seems to be obsolete. As long as there is AC input Vout is at close to zero volts.
What is the minimum current optovoupler for this opto. While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V. H11AA is supplied by Digikey and Mouser. Hence I started searching for it and found one i. This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat.

I am datassheet trying to get the state of an electrical device, i. Yes, I see you wrote, “sense when there is line and otherwise. It shows operation at uA and 1mA.
I calculated the voltage and found dataseet for V AC and a series resistance of K, the current is just 0. I changed R1 to K which greatly reduces heat. Fairchild still makes it.

Due to all these factors, someone suggested me to find another opto datasheft works at very low current. Anyway what is the minimum current for H11AA?
Sign up using Email and Password. Digikey is showing H11AA as obsolete. Email Required, but never shown. Also, I’d like to know exactly what you mean by “detect line voltage.

Post as a guest Name. Now I could reduce the resistance, however the heat dissipated optlcoupler be more which I don’t want. Schematics you’ve tried would be nice. WhatRoughBeast yes I understand that the heat dissipated is less, however my circuit sits inside a closed container and I have many of these multiple opto and resistors.
