Overview
The LV51130T 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 ±25m V
Over-discharge detection accuracy ±100m V
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.
