MAX1665S Datasheet Lithium-ion Battery Pack Protector

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1665S/V/X 19-1605; Rev 0; 1/00 Lithium-Ion Battery Pack Protector.

General Description

The MAX1665 provides protection against overvoltage, undervoltage, overcharge current, and overdischarge current for 2-cell to 4-cell lithium-ion (Li+) battery packs.

Very low operating current ensures that cells are not overdischarged during long storage periods.

The MAX1665 controls two external N-channel MOSFETs to limit the charge and discharge voltages.

Key Features
