[Outline]
This IC does not require an externally provided sensing resistor or reverse-current protection diode, enabling reductions in the component count and the amount of generated heat.
Battery safety is ensured by limiting the charging current and battery voltage when the battery is at high and low temperatures.
It conforms to the new PSE law.

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. The battery can therefore be charged with optimal charging regulation. |
6. |
Built-in charging timer. Charging timer time can be freely set using external resistor. |
