1 / 10 page UNISONIC TECHNOLOGIES CO., LTD UB261 Preliminary CMOS IC www.unisonic.com.tw 1 of 10 Copyright © 2014 Unisonic Technologies Co., Ltd QW-R502-A27.b 1-CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC DESCRIPTION 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. SOT-26 4 5 3 2 1 6 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~4.4V * Overcharge Release Voltage: VCL=3.8V~4.4V * Over Discharge Release Voltage: VDL=2.0V~3.0V * Over Discharge Release Voltage: VDU=2.0V~3.4V * Over Current 1 Detection Voltage: VIOV1=0.05V~0.30V * Over Current 2 Detection Voltage: VIOV2=0.5V (Fixed) * Short Circuit Detection Voltage: VSHORT=1.2V (Fixed) * Charger Detection Voltage: VCHA=-0.7V (Fixed) * Delay Times are Generated by an Internal Circuit. (External Capacitors are Unnecessary.) ORDERING INFORMATION Ordering Number Package Packing UB261G-xx-AG6-R SOT-26 Tape Reel Note: xx: Output Voltage, refer to Marking Information. |
