www.DataSheet.co.kr Ordering number : ENA1827A CMOS IC LV51132T Overview 2-Cell Lithium-Ion Secondary Battery Protection IC The LV51132T is a protection IC for 2-cell lithium-ion secondary batteries. Features • Monitoring function for each cell: • High detection voltage accuracy: • Hysteresis cancel function: • Discharge current monitoring function: • Low current consumption: • 0V cell charging function: Detects overcharge and over-discharge conditions and controls the charging and discharging operation of each cell. Over-charge detection accuracy ±25mV Over-discharge detection accuracy ±100mV The hysteresis of over-discharge detection voltage is cancelled by connection of a load after overcharging has been detected. Detects over-currents, load shorting, and excessively high voltage of a charger. Normal operation mode typ. 6.0μA Stand by mode max. 0.2μA Charging is enabled even when the cell voltage is 0V by giving a voltage between the VDD pin and V- pin.
