Description

The bq76PL102 PowerLAN dual-cell battery monitor is part of a complete scalable battery management system for use with arrays of up to 12 Li-Ion rechargeable cells. The bq76PL102 connects to one or two cells in a series string, performs voltage and temperature monitoring of each individual cell, and reports these parameters over the PowerLAN communication network. Together with a bq78PL114 master-gateway battery controller, the bq76PL102 forms a complete battery monitoring and management system for higher cell-count applications.

Partitioning of the battery monitor function on a per cell basis permits connection and measurement close to the cell. This results in superior accuracy and management over competing solutions.
