GENERAL DESCRIPTION
The NE57600 series is a family of small, high-precision lithium-ion
battery protection devices that provide protection against the
excessive current consumption such as happens if the consumer
uses the battery for an apparatus it was not meant to power. The
NE57600 is a single-cell Li-ion protection IC.
The NE57600 over and under voltage accuracy is trimmed to within
lithium-ion cells manufactured in the market today.
