Outline
This IC integrates overcharge/overdischarge protection functions for lithium-ion/lithium polymer rechargeable batteries and the regulator functions into one chip by high
voltage CMOS process. It can be used with other gas gauge IC, security IC, etc. as it includes a regulator. Overcharge/overdischarge can be detected to protect 4-cell lithium-ion/lithium polymer batteries. Charge/discharge control is perfomed using two external Pch MOS FETs.
Features
1. Overcharge detection
voltage
Selectable between 4.0~4.5V by 5mV steps
Accuracy ±25mV
2. Over-discharge detection
voltage Selectable between 2.0~3.0V by 100mV steps
Accuracy ±80mV
3. No external capacitor for delay time required (delay time is set by the internal circuit)
4. Regulator output
voltage
Selectable between 2.0~4.0V by 0.2V steps...
