Frequently Asked Questions
At what maximum data rate does the LTC6820HUD operate over an isolated twisted-pair link?
The LTC6820HUD supports isoSPI communication at up to 1 Mbps over a single twisted-pair cable, providing fast data transfer while maintaining galvanic isolation. This rate is sufficient for real-time cell voltage monitoring in large battery stacks with 16 or more series cells, enabling timely balancing and protection responses.
How does the LTC6820HUD simplify wiring in a multi-cell EV battery management system?
By translating standard SPI into an isoSPI differential signal on a single twisted pair, the LTC6820HUD reduces cabling from multiple wires to just 2 wires per node in a daisy-chain stack. A 100-cell EV battery pack can use a series of LTC6820 nodes each separated by only a twisted pair, eliminating the need for multiple isolated power supplies and reducing EMI susceptibility.
Why is the QFN-16 package of the LTC6820HUD advantageous for dense BMS PCB layouts?
The 16-pin QFN package provides a compact footprint that fits within tight PCB area constraints typical of battery management modules. Its exposed thermal pad improves heat dissipation, and the low-profile package reduces board height, making the LTC6820HUD compatible with slim battery pack enclosures where board space is limited to a few square centimeters.
