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, SA57608 can protect the battery pack against an accidental short-circuit. The overcharge trip point has a time delay which can be programmed externally. SA57608 is packaged in a space-saving 6-lead small outline package and requires two external N-channel MOSFETs and a minimum of passive parts.
