BQ7694003DBT TI Battery Monitor | 44-TSSOP | 3-15S, I2C, 1mA

Product Overview

The BQ7694003DBT is a high-performance battery monitor and protector from Texas Instruments, designed for 3-series to 15-series Li-Ion and LiFePO4 battery packs. It integrates a precision analog front end, a voltage regulator, and a microcontroller interface in a compact 44-TSSOP package. The device provides accurate voltage, current, and temperature monitoring, along with comprehensive protection features including overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature. It communicates via I2C interface, enabling easy integration with host controllers for battery management systems (BMS) in applications such as energy storage systems, power tools, and electric vehicles.
