LV51135T

Overview

The LV51135T 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 cancelled by

connection of a load after overcharging has been detected.

• Discharge current monitoring function:

Detects over-currents, load shorting, and excessively high voltage of a

charger.

• Low current consumption:

Normal operation mode typ. 6.0

μA

Stand by mode

max. 0.2

μA

• 0V cell charging function:

Charging is enabled even when the cell voltage is 0V by giving a

voltage between the VDD pin and V- pin.
