2-Cell Lithium-Ion Secondary Battery
Protection IC
Overview
The LV51134T 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 canceled by sensing
the connection of a load after overcharging has been detected.
Detects over-currents, load shorting, and excessively high voltage of a
charger and regulates charging and discharging operations.
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.
