What's the minmum voltage of Super capacitor(Vback voltage) need to let timer work when Vcc remove?
What's difference between operating and swithover on Backup supply voltage?

Hi Lane,
It means can enable switchover function when Vback voltage of BQ32000 is must above 2V.
When I remove Vcc and Vback voltage of BQ32000 is 1.4V, so BQ32000 can't keep work?
Do I understand correctly?
Thanks!
Kevin
Hi Kevin,
It is not clear how the device will respond to switchover if Vback < 2V. However, your understanding is correct.
Kind regards,
Lane
