The BQ29312APWR from Texas Instruments is an analog front-end (AFE) integrated circuit for 2-, 3-, or 4-cell lithium-ion battery pack protection. It incorporates a 3.3-V, 25-mA low-dropout regulator (LDO) and an I2C-compatible interface for extracting battery parameters such as cell voltages.
Key features include individual cell voltage monitoring, battery voltage reporting to the host, and integrated cell balancing drive. The device offers programmable thresholds and delays for overload and short-circuit conditions during both charge and discharge cycles. It also provides a system alert interrupt output and host control for initiating sleep and ship modes.
This IC is suitable for applications such as notebook PCs, medical and test equipment, and portable instrumentation. It operates within a temperature range of -40°C to 85°C and is supplied in a 24-TSSOP surface-mount package.
The BQ29312APWR is designed to interface directly with bq2084 gas gauges, providing comprehensive battery management capabilities. Its low supply current of 60-µA typical makes it an efficient choice for battery-powered devices.
