Hi Team,

how long it should roughly take for a BQ40Z50-R2 to exit IATA shutdown mode with CHECK_WAKE bit =0?

i.e. From the time "Voltage at PACK pin > VSTARTUP" to when the LEDs turn on?

Hi,

If IATA is disabled it will follow the standard boot sequence which could take up to 2.5seconds. You can monitor the [INIT] flag to know when the gauge is ready.

Thanks,

Jackson
