Description
This is a 3-cell series protection IC designed to protect lithium ion batteries from overcharging and excess discharging. It has a built-in function that turns off the external FET switch in case of abnormalities during charging or when the voltage for each battery falls below a set voltage during discharging. The IC also switches to low current consumption mode in such cases. With a protection circuit requiring few external parts, it is ideal for use with lithium ion batteries.
