UNISONIC TECHNOLOGIES CO., LTD UB261 Preliminary CMOS IC 1-CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC  DESCRIPTION 6 5 4 The UTC UB261 is a series of lithium-ion/lithium-polymer rechargeable battery protection ICs incorporating high accuracy voltage detection circuits and delay circuits. The UTC UB261 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 required external components make it ideal to integrate the UTC UB261 into the limited space of battery pack. 1 2 3 SOT-26  * * * * * * * * * * * * 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.
