[Outline]
This IC is a linear charging control IC with built-in system paths, and includes a chip with system path function and lithium ion/lithium polymer secondary battery charging function.
This IC features a built-in load switch with overvoltage detection function and input current limit required for system paths, and built-in power FETs, backflow prevention diodes, and current sensor function required for charging and discharging.
The IC comes equipped with an adapter and USB automatic recognition function, and allows the individual settings for charging control voltage and current with I2C communication.

[Features]
1. 
ADP/USB detection by using of USB bus(D+/D- pin).
2. 
I2Cbus control (CC/CV/Charge ON/OFF).
3. 
Support for JEITA(battery temperature profile).
4. 
System path current limit of ADP mode is adjustable by ILIM pin.
5. 
24V High Voltage tolerance(IN pin).
6. 
Support for operating system out from battery(built-in low on resistance FET).
7. 
Linear charger control for Li-ion,Li-pol.
8. 
charge current setting by ISET pin.
9. 
charge timer setting by TMR pin.
10. 
Indicator :
Input power connected (INGOOD pin).
Charge condition (CHG pin).
BAT voltage condition (OUTGOOD pin).
I2C alarm(SAL pin).
