Charger supervision functions
The charger supervision functions allow charging without processor control by continuously checking the NTC
temperature resistor within the battery pack using ADC_IN1 pin. The charging cycle is automatically paused, if the
NTC indicates a temperature range out of 0o to 45o (or 0o to 50o). If the temperature gets into this range again the
charging cycle is resumed.
In addition there is a charge timer that stops charging after a defined time, as additional security feature.
The timer will be reset at charger insertion (charger detect) or at EOC state. The timer is counting during active
charging only (Trickle charging, Constant current charging, Constant voltage charging).
In case the battery voltage does not reach EOC voltage within t CHARGINGMAX after charging has been started,
charging_tmax interrupt will be generated and charging will be stopped. Charging can be started again by writing
charging_tmax=0 in the charger_control1 register.
