Description
The bq76925 host-controlled analog front end (AFE) is part of a complete 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, under-voltage, overtemperature, overcurrent, cell imbalance, state of charge, and state of health conditions.
Features
1. Analog Interface for Host Cell Measurement
2. Switchable Thermistor Bias Output for Host Temperature Measurements
3. Supports Cell Sense-Line Open Wire Detection
