BQ76925 datasheet pdf


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.


1. Analog Interface for Host Cell Measurement

2. Switchable Thermistor Bias Output for Host Temperature Measurements

3. Supports Cell Sense-Line Open Wire Detection




1. Primary Protection in Li-Ion Battery Packs

(1) Cordless Power Tools
(2) Light Electric Vehicles (E-Bike, Scooter, and so forth)
(3) UPS Systems
(4) Medical Equipment
(5) Portable Test Equipment
