Preliminary

CMOS IC

1-CELL LITHIUM-ION/POLYMER

BATTERY PROTECTION IC



DESCRIPTION

UTC UB211C is

a series of lithium-ion / lithium-polymer

rechargeable battery protection ICs incorporating high accuracy

voltage detection circuits and delay circuits.

UTC UB211C is suitable for protection of single cell lithium-ion /

lithium polymer battery packs from overcharge, over discharge and

over current.

The ultra-small package and less requirement of external

components make it ideal to integrate the UTC UB211C into the

limited space of battery pack.



FEATURES

* Wide Supply Voltage Range: V_DD=1.5V~8.0V

* Ultra-Low Quiescent Current: I_OPE=3.0μA (V_DD=3.5V)

* Ultra-Low Power-Down Current: I_PDN=0.2μA (V_DD=1.5V)

* Overcharge Detection Voltage: V_CU=3.9V~4.4V

* Overcharge Release Voltage: V_CL=3.8V~4.4V

* Over Discharge Release Voltage: V_DL=2.0V~3.0V

* Over Discharge Release Voltage: V_DU=2.0V~3.4V

* Discharge Over Current Detection Voltage: V_DOIV=0.05V~0.30V

* Discharge Short Circuit Detection Voltage: V_SHORT=0.5V (Fixed)

* Charge Over Current Voltage: V_COIV=-0.1V (Fixed)

* Charger Detection Voltage: V_CHA=-0.7V (Fixed)

* Delay Times are Generated by an Internal Circuit. (External Capacitors are Unnecessary.)
