bq79731-Q1 High-Voltage Battery Pack Monitor

Texas Instruments bq79731-Q1 High-Voltage Battery Pack Monitor can measure divided down high voltage nodes in a battery system. It can measure the voltage across contractors, fuse, and check isolation voltage in a battery junction box (BJB) system. The device has two integrated current sense paths supporting a low-side shunt resistor. Accurate SOC calculation is available because of the coulomb counting function. There are 15 GPIOs/auxiliary inputs that can be used for thermistor measurements, HV measurements, and driving relays. Four SW outputs can drive MOSFET switches in the measurement path. The device can function as an interface and SPI HUB with up to eight separate SPI devices/groups. Over-current protection response can be achieved autonomously using HW pins for fast protection in dangerous over-current events. The isolated bi-directional daisy chain ports support transformer-based and capacitor isolation. The device can also communicate with MCU over UART and SPI. Typical applications for the Texas Instruments bq79731-Q1 include fully electric, plug-in hybrid, and hybrid vehicles.
