UNISONIC TECHNOLOGIES CO., LTD UB211C Preliminary 1-CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC CMOS 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: VDD=1.5V~8.0V * Ultra-Low Quiescent Current: IOPE=3.0μA (VDD=3.5V) * Ultra-Low Power-Down Current: IPDN=0.2μA (VDD=1.5V) * Overcharge Detection Voltage: VCU=3.9V~4.
