www.DataSheet.co.kr Ordering number : ENA1151 CMOS IC LV51138T Overview 2-Cell Lithium-Ion Secondary Battery Protection IC The LV51138T 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 made small by sensing the connection of a load after overcharging has been detected.
