Hi ,

I am using TPS65910A3 to design my power system.

I have one key(or two keys ) use as a power on (power off) key.

Should I connect the button to which pin of TPS65910A3?

Thank you so much.

Hi Shanqing Liu,

A push button can be connected to the PWRON pin, pin 33 of the TPS65910xx. You can refer to page 49 of the TPS65910x datasheet for further information. You can use a single key to turn the PMIC on and off. A short press results in a transition from an OFF-to-ACTIVE or SLEEP-to-ACTIVE state. A longer push button press will force the PMIC from an ACTIVE-to-OFF state. Does this answer your question?
