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.
