MAX6775 - 1%-Accurate Battery Monitors

General Description

The MAX6775

MAX6781 low-power, 1%-accurate battery monitors are available in the ultra-small µDFN package (1.0mm x 1.5mm) and SC70 packages.

These low-power devices are ideal for monitoring single lithium-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources.

Key Features

19-3774; Rev 4; 5/09 www.DataSheet4U.com Low-Power, 1%-Accurate Battery Monitors in µDFN and SC70 Packages General Description The MAX6775–MAX6781 low-power, 1%-accurate battery monitors are available in the ultra-small µDFN package (1.0mm x 1.5mm) and SC70 packages. These low-power devices are ideal for monitoring single lithium-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources. These devices offer single (MAX6775/ MAX6776/MAX6777/MAX6778) or dual (MAX6779/ MAX6780/MAX6781) low-battery outputs and feature fixed or resistor-adjustable hysteresis. Hysteresis eliminates the output chatter sometimes associated with battery voltage monitors, usually due to input-voltage noise or battery terminal voltage recovery after load removal.
