LV5122T
Overview
The LV5122T 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 canceled 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.
Low current consumption:
Normal operation mode typ. 6.0
A
Stand by mode
max. 0.2
A
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.
Ordering number : ENA0728A
