The BQ7694001DBT is a battery monitor IC from Texas Instruments, part of the BQ769x0 family, suitable for multi-chemistry battery packs. It supports 9 to 15 series cells and provides comprehensive monitoring and protection.
Key electrical features include an input voltage rating of up to 75V, an I2C communication interface, and a typical operating current of 40 µA. The device offers battery overvoltage protection from 3.15V to 4.7V. It integrates an Analog Front End (AFE) with a pure digital interface, an internal ADC for cell voltage and temperature measurement, and a separate ADC for pack current (coulomb counter). It can directly support up to three thermistors.
Hardware protection features include Overcurrent in Discharge (OCD), Short Circuit in Discharge (SCD), Overvoltage (OV), Undervoltage (UV), and secondary protector fault detection. Additional features include integrated cell balancing FETs, charge/discharge low-side NCH FET drivers, an alert interrupt to the host microcontroller, and a 2.5V or 3.3V output voltage regulator. It operates over a temperature range of -40°C to 85°C.
The BQ7694001DBT is available in a 44-TSSOP surface mount package. This IC is designed for high-power systems such as light electric vehicles, power tools, and uninterruptible power supplies, serving as part of a complete pack monitoring and protection solution.
