PRODUCTION DATA.
The bq25700A charges 1-4 cell battery in constant current (CC), and constant voltage (CV) mode. Based on CELL_BATPREZ pin setting, the charger sets default battery voltage 4.2V/cell to ChargeVoltage(), or REG0x15(). According to battery capacity, the host programs appropriate charge current to ChargeCurrent(), or REG0x14(). When battery is full or battery is not in good condition to charge, host terminates charge by setting REG0x12[0] to 1, or setting ChargeCurrent() to zero.
