Frequently Asked Questions
How many battery cells can the LTC6811HG-2#PBF monitor per device, and can multiple units be stacked for larger packs?
Each LTC6811HG-2#PBF monitors 12 series-connected battery cells simultaneously using its built-in high-accuracy ADC. Multiple devices can be daisy-chained via the isoSPI interface, allowing systems to scale to hundreds of series cells in automotive EV battery packs without requiring additional isolation hardware, since isoSPI provides inherent galvanic isolation between the daisy-chained nodes.
Is the LTC6811HG-2#PBF suitable for use in automotive EV battery management systems at elevated temperatures?
Yes, the LTC6811HG-2#PBF is automotive-grade and housed in a 48-pin SSOP package, qualified to operate across the extended automotive temperature range typically spanning -40°C to +125°C. This makes it suitable for underhood or battery pack enclosure environments in electric vehicles, hybrid cars, and commercial vehicles where temperature cycling and vibration are key reliability requirements.
What communication interface does the LTC6811HG-2#PBF use, and how does it simplify wiring in a high-voltage battery stack?
The LTC6811HG-2#PBF uses an isoSPI interface, a proprietary differential signaling protocol that provides data rates up to 1 Mbps over a single twisted-pair cable while maintaining isolation between high-voltage stack segments. This dramatically reduces wiring harness complexity in a 48-channel or larger battery system compared to running individual measurement wires to each cell group, cutting both cost and assembly time in EV battery packs.
