Single-cell Li-ion / Li-polymer Battery Protection IC
A7B Series
GENERAL DESCRIPTIONS
The A7B series are protection ICs for rechargeable Li-ion / Li-polymer battery by
high withstand voltage CMOS process. These series protect single-cell Li-ion /
Li-polymer battery from over-charge, over-discharge, charge over-current and
discharge over-current.
