The BQ79614PAPRQ1: Communicates over SPI and UART, giving the BMS controller a choice of serial bus depending on the existing harness topology. The over-temperature fault protection shuts down the monitor before the die exceeds the safe junction limit — critical for a part sitting on the battery pack where thermal runaway is the primary failure mode.
The primary difference is the number of monitored cells or precision level; check the BQ79612 datasheet against your cell-count requirement before substituting.
