SA57608
One-cell Lithium-ion battery protection with
over/undercharge and overcurrent protection

2003 Oct 29
GENERAL DESCRIPTION
The SA57608 is a single-cell Li-ion protection IC, and is an improved
version of the NE57600, with different pinout. Its over and under
voltage accuracies are trimmed to within
±
25 mV (5%) over the
entire battery pack operating temperature range. The SA57608 is
available in various over and undervoltage limits.
There is a discharge overcurrent protection circuit which can protect
the battery pack against an accidental short-circuit. The overcharge
trip point has a time delay which can be programmed externally. It is
packaged in a space-saving 6-lead small outline package and
requires two external N-channel MOSFETs and a minimum of
passive parts.
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 quiescent sleep current 0.05 mA
Discharge overcurrent cutoff
Low operating current (10 A)
6-lead small outline package (SOP004)
APPLICATIONS
Cellular phones
Personal digital assistants
Palmtop computers
