Description

The NE57606 is a redundant overcharge detection IC for use within 2-4 cell Li-ion battery packs. It detects the voltage of each Li-ion cell and issues an overcharge signal which then can be used to alert the portable host or be used to turn-off a series charge MOSFET within the battery pack. NE57606's purpose is to act as a back-up protection circuit to a primary Li-ion protection circuits such as the NE57605 and NE57607. The overcharge signal is an open collector output which can be wire-ORed with other safety functions.
