TX810: Power supply independence of VP and VD

David Whitehouse

Part Number: TX810

Hello,

We have a design where to save power we would like to power down VP and VN (turn the +-5V rails OFF) while leaving VD powered at 3V3 - will this cause an issue?

Kind regards,

Dave

Hi,

I checked datasheet and didnt find any power supply sequencing constraint. So it means that any sequencing would be fine. So keeping VD powered up and other supply turn OFF will be ok since it is within allowed operating condition.

Regards,
