1 / 10 page  UNISONIC TECHNOLOGIES CO., LTD UB24205 Preliminary CMOS IC www.unisonic.com.tw 1 of 10 Copyright © 2009 Unisonic Technologies Co., Ltd QW-R121-019.a LITHIUM-ION/POLYMER BATTERY PROTECTION IC DESCRIPTION The UTC UB24205 is a lithium-ion / lithium-polymer rechargeable battery protection IC with internal MOSFETs. It incorporates high accuracy voltage detection circuits and delay circuits. The UTC UB24205 is suitable for protection of single cell lithium-ion / lithium polymer battery packs from overcharge, over discharge and over current. The small package and less required external components make it ideal to be integrated into limited space of battery pack. FEATURES * Wide supply voltage range: VDD=1.8V~9.0V * Ultra-low quiescent current: IDD=3.0μA (VDD=3.9V) * Ultra-low power-down current: IPD=0.1μA (VDD=2.0V) * Overcharge detection voltage: VOCU=4.250V±0.050V * Overcharge release voltage: VOCR=4.055V±0.050V * Over discharge release voltage: VODL=2.250V±0.100V * Over discharge detection voltage: VODR=2.850V±0.100V * Over current detection voltage: VOI1= 0.150V±0.030V * Short circuit detection voltage: VOI2=1.35V (Fixed) * Charger detection voltage: VCH=-0.7V * Reset resistance for over current protection: RSHORT>500kΩ * No external MOSFETs * Delay times are generated by an internal circuit (External capacitors are unnecessary). * Halogen Free ORDERING INFORMATION Ordering Number Package Packing UB24205G-S08-R SOP-8 Tape Reel |
