Hi,

my customer want to achieve that BQ25895 can send interrupt to wake up the processor when VBAT falls to a threshold. Is it possible?

    Hi,

    Please refer to below on the d/s.

    8.2.9.2 Interrupt to Host (INT)

    In some applications, the host does not always monitor the charger operation. The INT notifies the system on the device operation. The following events will generate 256-µs INT pulse.

    • USB/adapter source identified (through PSEL or DPDM detection, with OTG pin)

    • Good input source detected – VBUS above battery (not in sleep) – VBUS below VACOV threshold – VBUS above VVBUSMIN (typical 3.8 V) when IBADSRC (typical 30 mA) current is applied (not a poor source)

    • Input removed

    • Charge Complete

    • Any FAULT event in REG0C

    Thanks,

    Ning.
