[Outline]
This IC is a linear charge control IC for 1-cell Lithium-Ion and lithium-polymer batteries. It incorporates a power MOSFET and a reverse-current block circuit for easy implementation of charge control of Lithium-Ion and Lithium-polymer batteries without an external sense resistor and a reverseblocking diode.
The chip temperature detection function can limit the temperature rise in the IC during high power charging and the temperature detection function enables the temperature for charge to be controled. This IC uses a small PLP-10pin package.

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 the temperature for charge to be controled. |
