BQ40Z50-R2: Auto wake up from Shutdown mode

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: BQ40Z50

About EVM of bq40z50, WAKE button is mounted and it is used to wake up the IC from shutdown mode.
I'd like to know how to exclude this procedure.

Can I short the Wake button (Connect 4P-10kohm-PAKC+) ? or is there any other solution to wake up from shutdown mode without button ?

    Hello Fuji,

    The wake button is to wakeup in case of shutdown for testing, depending on your application you can use the function to wake up, you just have to apply a voltage greater than Vstartup to the PACK pin for wakeup.

    It's designed to wakeup when a charger is attached.

    Sincerely,
