UB211C

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~4.4V * 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 * Discharge Over Current Detection Voltage: VDOIV=0.05V~0.30V * Discharge Short Circuit Detection Voltage: VSHORT=0.5V (Fixed) * Charge Over Current Voltage: VCOIV=-0.1V (Fixed) * Charger Detection Voltage: VCHA=-0.7V (Fixed) * Delay Times are Generated by an Internal Circuit. (External Capacitors are Unnecessary.)  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UB211CL-xx-AF5-R UB211CG-xx-AF5-R Note: xx: Output Voltage, refer to Marking Information.
