Protection IC
Overview
The LV5124T is a protection IC for 2-cell lithium-ion secondary batteries.
Features
• Monitoring function for each cell:
Detects overcharge and over-discharge conditions and controls the
charging and discharging operation of each cell.
• High detection voltage accuracy:
Over-charge detection accuracy ±25mV
Over-discharge detection accuracy ±100mV
• Hysteresis cancel function:
The hysteresis of over-discharge detection voltage is made small by
sensing the connection of a load after overcharging has been detected.
• Discharge current monitoring function:
Detects over-currents and load shorting, and an excessive
discharge current is controlled.
• Latch function after detecting over-current (Release is made by connecting the charger)
• Low current consumption:
Normal operation mode typ. 6.0µA
Stand by mode
max. 0.2µA
• 0V cell charging function:
Charging is enabled even when the cell voltage is 0V by giving a
potential difference between the VDD pin and V- pin.
