1. BAT Regulation Voltage 4.2V±30mV(0.7%) 2. Fast Charge Current 558mA±5% 3. Preliminary current, high-speed charging current, charging completion current can be set using external resistors (maximum charging current is 1.5 A) . 4. A battery temperature detection function is provided via a thermistor, and so the charging voltage and current can be controlled according to the battery temperature. 5. Chip temperature detection enables control of IC temperature rises at high-power charging.
