The BQ78PL116 from Texas Instruments is a PowerLAN Master Gateway Battery Management Controller designed for managing 3- to 16-series cell battery systems. It incorporates PowerPump technology for efficient charge transfer between cells, enhancing run time and cell life. This controller supports external capacity indication via EPD and LCD displays and features a high-resolution 18-bit integrating delta-sigma Coulomb counter for precise charge flow measurements and gas gauging.
Key electrical specifications include configurable operating currents of 11-A, 26-A, or 110-A. The device offers very low power consumption, with active current less than 400 µA, standby less than 185 µA, ship less than 85 µA, and undervoltage shutdown less than 1 µA. It communicates via SMBus and is compatible with Li-Ion/Li-Polymer cell chemistries. The operating temperature range is from -40°C to 85°C.
Designed for safety and performance, the BQ78PL116 provides fully programmable voltage, current, balance, and temperature-protection features. It supports fail-safe operation of pack protection circuits, including up to three power MOSFETs and one secondary safety output. Systems with more than four series cells require external bq76PL102 dual-cell monitors. The controller is suitable for applications such as portable medical instruments, mobility devices (e-bikes), and uninterruptible power supplies.
The BQ78PL116 is available in a VQFN (RGZ) 48 package, measuring 7 mm x 7 mm with an area of 49 mm². This compact package is suitable for various integration needs.
