TPS65916: Setting for Long Press Key duration

Satoshi
Guru 19645 points
Part Number: TPS65916

I found Long Press Key (OFF) duration choice below register from 4 sec to 10 sec. 

Is there way to Long Press Key duration mask (0 sec) or over than 10 sec?

And if over than 10 sec can set, please let me know maximum Long Press key duration.

↓Page 78 is described

Best regards,

Satoshi

    Satoshi-san,

    I have assigned this question to the expert on the TPS65916 device and I expect you will receive a response today (by EOD U.S. Central time).

    Hello Satoshi-san,

    There is not a way to adjust the LPK time beyond the values that are in the silicon unforunately.

    For shorter times, the processor would most likely need to sense the PWRON pin and perform a software shutdown. 

    For longer times, a discrete circuit in front of the PMIC could potentially be designed using a timer & counter to prevent the LPK of 10 s from being triggered by toggling the PWRON pin.

    Hopefully this helps!
