The BQ7694003DBT from Texas Instruments is a robust analog front-end (AFE) device designed for battery monitoring and protection in high-power systems. It supports 9 to 15 series cells for Li-ion and Li-phosphate chemistries.
Key electrical features include an I2C communication interface, an input voltage rating of up to 75V, and typical operating current of 40 µA. The device provides overvoltage protection from 3.15V to 4.7V and includes hardware protection for overcurrent, short circuit, overvoltage, and undervoltage conditions. It also features integrated cell balancing FETs and low-side NCH FET drivers for charge and discharge control.
This IC is housed in a 44-TSSOP surface mount package. Its AFE monitoring capabilities include an internal ADC for cell voltage, die temperature, and external thermistor measurements, as well as a separate ADC for pack current via a coulomb counter. It directly supports up to three thermistors.
The BQ7694003DBT is suitable for applications such as light electric vehicles, power tools, and uninterruptible power supplies, offering a complete pack monitoring and protection solution.
