[Outline]
This IC is a linear charge control IC for 1-cell lithium iron phosphate (LiFePO4) battery.
The chip temperature detection function can limit the temperature rise in the IC during high power charging and the battery temperature detection function enables the Charging by temperature to be controlled.
The package is a small size SSON-10pin.

[Features]
1. 
BAT Regulation Voltage
3.6V±30mV(±0.8%)
2. 
Fast Charge Current
558mA±5%(RICHG=2.32kΩ)
3. 
The external resistor enables trickle/fast-charge current/charge completion current to be set
(Maximum charge current : 1.5A).
4. 
A charge timer is embedded in this IC. The external resistor enables the charge timer to be set arbitrarily.
5. 
The chip temperature detection function can limit the temperature rise in the IC during high power charging. It can be charged at an optimal rate.
6. 
The battery temperature detection function with thermistor input enable Charging by temperature to be controlled.
7. 
LED Driver (1ch)
