PRODUCTION DATA.
The charger includes watchdog timer to terminate charging if the charger does not receive a write MaxChargeVoltage() or write ChargeCurrent() command within 175 s (adjustable via REG0x01[6:5]). When watchdog timeout occurs, all register values are kept unchanged except ChargeCurrent() resets to zero. Battery charging is suspended. Write MaxChargeVoltage() or write ChargeCurrent() commands must be re-sent to reset watchdog timer and resume charging. Writing REG0x01[6:5] = 00 to disable watchdog timer also resumes charging.
