Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity bq76925 SLUSAM9D – JULY 2011 – REVISED OCTOBER 2016 bq76925 Host-Controlled Analog Front End for 3-Series to 6-Series Cell.

General Description

The bq76925 host-controlled analog front end (AFE) is part of a plete pack monitoring, balancing, and protection system for 3-, 4-, 5-, or 6-series cell Li-Ion and Li-Polymer batteries.

The bq76925 device allows a Host controller to monitor individual cell voltages, pack current and temperature easily.

The Host may use this information to determine unsafe or faulty operating conditions such as overvoltage, undervoltage, overtemperature, overcurrent, cell imbalance, state of charge, and state of healt
