BQ7694000DBTR Description

Short technical summary and product information.

The Texas Instruments BQ7694000DBTR is a versatile analog front-end (AFE) device designed for comprehensive battery pack monitoring and protection in high-power systems. It supports battery configurations from 9 to 15 series cells, making it suitable for Li-Ion and Li-iron phosphate chemistries.

 

Key features include a pure digital interface, internal ADCs for cell voltage, die temperature, and pack current (coulomb counter) measurements. It also supports up to three external thermistors. Hardware protection includes overcurrent in discharge (OCD), short circuit in discharge (SCD), overvoltage (OV), and undervoltage (UV) detection.

 

Additional functionalities comprise integrated cell balancing FETs, charge/discharge low-side N-channel FET drivers, and an alert interrupt to the host microcontroller. The device operates over a temperature range of -40°C to 85°C and communicates via a simple I2C compatible interface. It is supplied in a 44-TSSOP package suitable for surface mounting.

 

This IC is ideal for applications such as light electric vehicles (eBikes, eScooters), power tools, battery backup units (BBUS), energy storage systems (ESS), and uninterruptible power supply (UPS) systems.
