LV51139T

www.DataSheet.co.kr Ordering number : ENA1927 CMOS IC LV51139T Overview 2-Cell Lithium-Ion Secondary Battery Protection IC The LV51139T 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: Absolute Maximum Ratings at Ta = 25°C Parameter Power supply voltage Input voltage Charger minus voltage Output voltage Cout pin voltage Dout pin voltage Allowable power dissipation Operating ambient temperature Storage temperature Vcout Vdout Pd max Topr Tstg Independent IC VDD-28 to VDD+0.3 VSS-0.3 to VDD+0.3 170 -30 to +85 -40 to +125 V V mW °C °C Symbol VDD VConditions Ratings -0.3 to +12 VDD-28 to VDD+0.3 Unit V V 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. 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 potential difference between the VDD pin and V- pin.
