UB2421
Overview
- Wide supply voltage range: VDD=1.8V~6.5V * Ultra-low quiescent current: IDD=3.0μA (VDD=3.5V) * Ultra-low power-down current: IPD=0.2μA (VDD=2.0V) * Overcharge detection voltage: VOCU=4.30V±0.05V * Overcharge release voltage: VOCR=4.10V±0.05V * Overdischarge release voltage: VODL=2.40V±0.10V * Overdischarge release voltage: VODR=3.00V±0.10V * Over current detection voltage: VOI1=0.15V±0.05V * Short circuit detection voltage: VOI2=1.35V (Fixed) * Charger detection voltage: VCH=-0.7V * Delay times are generated by an internal circuit. (External capacitors are unnecessary.)
