PRODUCTION DATA
During low power mode (EN_LWPWR = 1), the charger offers a low power PROCHOT function with very low quiescent current consumption (~35 μA), which uses the independent comparator to monitor the system voltage, and assert PROCHOT to CPU if the system power is too high and resulting system voltage is lower than specific threshold.
Below lists the register setting to enable PROCHOT monitoring system voltage in low power mode.
