The BQ79735B-Q1 device can be used to measure divided down high voltage nodes in a battery system. The device can measure voltage across Fuse, Contactors and check isolation voltage in battery junction box (BJB) system. There are 15 GPIOs/auxiliary inputs that can be used for HV measurements, thermistor measurements and driving relays. There are 4 SW outputs that can be used to drive MOSFET switches in the measurement path. The device can function as a SPI HUB and interface with up to 8 separate SPI devices/groups. The isolated bi-directional daisy chain ports support both capacitor and transformer based isolation. The device can also communicate with MCU over SPI.
