GENERAL DESCRIPTION
The NE57600 series is a family of small, high-precision lithium-ion
battery protection devices that provide protection against the
damaging effects of overcharging, overdischarging, short circuit, and
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
±25 mV (5%) and is available to match the requirements of all
lithium-ion cells manufactured in the market today.
FEATURES
Trimmed overvoltage trip point to within ±25 mV
Programmable overvoltage trip time delay
Trimmed undervoltage trip point to within ±25 mV
Very Low undervoltage sleep quiescent current 0.05 mA
Discharge overcurrent cutoff
Low operating current (10 mA)
Very small SOT-26A package
APPLICATIONS
Protecting one-cell Li-ion battery packs for mobile phones or
palmtop devices
