NE57600 - Philipss

NE57600 One-cell Lithium-ion battery protection with over/undercharge and overcurrent protection

The NE57600 series is a family of small, high-precision lithium-ion battery protection devices that provide protection against the damaging effects of overcharging, overdischarging, short circuit, and excessive current consumption such as happens if the consumer uses the battery for an apparatus it was not meant to power. The NE57600 is a single-cell Li-ion .
