STPM01 STPM10 STPM34 Zero Crossing Signal (ZCR) latency

What is the ZCR signal latency with respect to the line voltage for the STPM01 or STPM10?

Is the ZCR delay really 5ms for the STPM32 family with respect to the line voltage?

thanks,

Bruck

Hi Bruck

Are you working with STM32 or another product?

Thanks

There's probably no appropriate Forum for this kind of products here. This is a family of

http://www.st.com/en/data-converters/metering-ics.html

, to measure power consumption on a mains line.

It might be perhaps a good idea to sync the Forums' structure with the products structure on the main ST site, or maybe add a 'Other products' forum.

After talking with

st.mcu

I have moved this post to 

https://community.st.com/community/power-management-and-motor-control

.  Someone should be able to assist with this query there.

Thanks

Thanks Oliver and JW!  We are interested in the STPM01.  The zero crossing latency is important for the project. We are no longer considering the STPM32.
