Low Cost isoSPI Coupling Circuitry for High Voltage High Capacity Battery Systems
Safely extract the potential of large battery packs via precise monitoring of every cell. The LTC6804 Battery Monitor measures cell voltage with less than 0.04% error, guaranteed. Measurement stability over time, temperature and operating conditions is achieved with a buried Zener voltage reference, similar to those in precision instrumentation. A programmable 3rd order noise filter keeps noise from corrupting cell measurements, and a 2-wire isoSPI interface provides a cost-effective, noise immune, 100 meter interconnection for multiple LTC6804s.
