Outline
This is a 3-cell series protection IC is for protecting a lithium ion battery
from overcharging and excess discharging. If abnormalities occur during
charging and excess voltage is applied, it has a function that turns off the
external FET switch (overcharging detection). It also has a function that
turns off the external FET switch when the voltage for each battery falls
below a set voltage, to prevent excess discharge when discharging the battery
(discharging detection). At that time, the IC is switched to low current
consumption mode.
These functions comprise a protection circuit, with few external parts, for
lithium ion batteries.
