LTC6810 6-Channel Multi-Cell Battery Monitor

Analog Devices LTC6810 6-Channel Multi-Cell Battery Monitor measures up to six series-connected battery cells with a total measurement error of less than 1.8mV. The cell measurement range of 0V to 5V makes the LTC6810 suitable for most battery chemistries. All six cells can be measured in 290μs, and lower data acquisition rates can be selected for high noise reduction. Multiple Analog Devices LTC6810-1 devices can be connected in series, permitting simultaneous cell monitoring of long, high-voltage battery strings. Each LTC6810 has an isoSPI™ interface for high-speed, RF-immune, long-distance communications. Using the LTC6810-1, multiple devices are connected in a daisy chain with one host processor connection for all of the devices. The LTC6810-1 supports bidirectional operation, allowing communication even with a broken wire. Using the LTC6810-2, multiple devices are connected in parallel to the host processor with each device individually addressed.
