Datasheet
Panther Lithium Battery Protection Module
The Panther module is a Lithium battery protection circuit, which is designed to enhance the operating life of a
one-cell rechargeable battery pack. Cell protection features include internally trimmed charge and discharge
voltage limits as well as charge and discharge current limit detection. The voltage and current ratings are
designed for the use in battery packs for portable phones, paging systems, music players and other portable
equipment such as “Bluetooth” applications.
