[Outline]
This IC is a linear charge control IC for low capacity battery.
Charging from 0V of battery voltage is available, so this IC is optimum for product used low-capacity battery.
Charge control voltage can be set according to a battery to be used. (4.2 or 4.05V)

[Features]
1. 
BAT Regulation Voltage
4.2V±30mV(0.7%) / 4.05V±50mV (Setting by CVSEL pin)
2. 
Fast Charge Current
15mA±1.8mA RICHG=74.2kΩ
3. 
Charging from 0V of battery voltage.
4. 
Trickle-charge current, Fast-charge current, Charge completion current can be set using external resistors (maximum charging current is 0.7A).
5. 
Battery temperature detection function is provided via a thermistor, and so the charging ON/OFF can be controlled according to the battery temperature.
6. 
Chip temperature detection enables control of IC temperature rises at high-power charging. The battery can therefore be charged with optimal charging regulation.
7. 
Built-in charging timer. Charging timer time can be freely set using external resistor.
8.
