Frequently Asked Questions
How accurately does the LTC6811HG-1 measure individual cell voltages in a 12-cell stack?
The LTC6811HG-1 uses a 16-bit delta-sigma ADC and achieves a total measurement error of ±0.04% across all 12 cells. Individual cell voltage measurements are completed in under 1.1 ms for the full 12-channel stack using the 7 kHz bandwidth mode. This level of accuracy is critical for state-of-charge estimation in lithium-ion battery packs operating between 0 V and 5 V per cell.
In which battery pack architectures does the LTC6811HG-1#3ZZPBF deliver the most value compared to simpler monitor ICs?
The LTC6811HG-1#3ZZPBF excels in multi-stack architectures typical of EV powertrains and grid-scale storage where up to 31 units can be daisy-chained via isoSPI to monitor 372 series cells simultaneously. Its on-chip passive balancing at 200 mA per cell and programmable over-voltage threshold from 0 V to 5 V per cell eliminate the external comparators that simpler 4- or 6-cell monitors require, reducing BMS board count and design complexity in high-voltage systems operating above 100 V.
Is the LTC6811HG-1#3ZZPBF lead-free, and what package is it available in for production procurement?
The LTC6811HG-1#3ZZPBF is not lead-free (JESD-609 Code e3 indicates it contains lead), making it suited for high-reliability military and industrial applications where leaded solder is permitted. It is housed in a 48-pin SSOP (R-PDSO-G48) package, and the '#3ZZ' suffix denotes a tape-and-reel packaging option. Buyers in commercial EV programs requiring RoHS compliance should verify the lead-free variant availability before sourcing.
