GENERAL DESCRIPTION
The NE57607 is a family of 2-cell Li-ion protection ICs. 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.
The NE57607 comes in the small VSOP-8A package.
FEATURES
Trimmed overvoltage trip point to within ±25 mV

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 package VSOP-8A
APPLICATIONS
Cellular phones
Palmtop computers
