The BQ7693002DBTR from Texas Instruments is a robust analog front-end (AFE) device designed for battery monitoring and protection in multi-cell Li-ion and Li-phosphate battery packs. This IC supports configurations from 6 to 10 series cells, making it suitable for applications requiring typical 36V packs.
Key features include a pure digital interface with an internal ADC for measuring cell voltage, die temperature, and external thermistors, as well as pack current via a coulomb counter. Hardware protection is provided against overcurrent in discharge (OCD), short circuit in discharge (SCD), overvoltage (OV), and undervoltage (UV). The device also integrates cell balancing FETs and low-side NCH FET drivers for charge and discharge control.
With a simple I2C compatible interface, the BQ7693002DBTR facilitates communication with a host microcontroller. It operates within a temperature range of -40°C to 85°C and is available in a 30-TSSOP surface mount package. The device offers a 2.5-V or 3.3-V output voltage regulator and does not require EEPROM programming, simplifying implementation.
Applications for the BQ7693002DBTR include light electric vehicles (e.g., eBikes, eScooters), power tools, garden tools, battery backup units (BBUS), energy storage systems (ESS), and uninterruptible power supply (UPS) systems.
