GENERAL DESCRIPTION
The NE57605 is a 3-4-cell Li-ion protection IC. Its 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 2 mA.
Discharge overcurrent cutoff.
Low operating current (10 mA).
Very small package (TSOP-20A).
APPLICATIONS
Laptop Computers
Other battery-powered devices
