Lithium-Ion Battery ICs INDEX	\| HTML \| PDF \|

[Outline]

This charge control IC has characteristics to monitor battery temperature to control the charge current and charge voltage, and it is in compliance with the Safety Standard that will be put in force in 2011. In addition, this IC has achieved high cost performance in that it has integrated with charge FET and current sensing resistor, which are the external devices in the conventional charge control ICs, and that the reverse current protection function is added.

[Features]

1.	Integrated battery temperature monitor and battery control functions in advance preparation for the Safety Standard slated to be effective in 2011. Safety of the battery is secured by changing the full charge voltage and charge current when the battery temperature is low and high.
2.	Can reduce parts and its installation costs thanks to the integrated charging FET and current sensing resistor.
3.	Because of the control function integrated in the primary side, it is also possible to charge the battery highly effi ciently by tracking the battery voltage in addition to the charge control. Furthermore, the heat dissipation is minimized.
