The charger includes a watchdog timer to terminate charging if the charger does not receive a write ChargeVoltage() or write ChargeCurrent() command within 175s (default value and adjustable via WDTMR_ADJ). When watchdog timeout occurs, all register values are kept unchanged except ChargeCurrent() resets to 0 A . Write ChargeVoltage() or write ChargeCurrent() commands must be resent to reset watchdog timer. Writing WDTMR_ADJ = 00b to disable watchdog timer or update new watchdog timer values can also reset watchdog timer. New non-zero charge current value has to be written to ChargeCurrent() register to resume charging after watchdog timer expires.
