MAX14921 Datasheet (max14920 / Max14921) High-accuracy 12-/16-cell Measurement Afes

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE MAX14920/MAX14921 High-Accuracy 12-/16-Cell Measurement.

General Description

The MAX14920/MAX14921 battery measurement analog front-end devices accurately sample cell voltages and provide level shifting for primary/secondary battery packs up to 16 cells/+65V (max).

The MAX14920 monitors up to 12 cells, while the MAX14921 monitors up to 16 cells.

Both devices simultaneously sample all cell voltages, allowing accurate state-of-charge and source-resistance determination.
