Description
The LTC®6810 is a multicell battery stack monitor. The LTC6810 measures up to 6 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 6 cells can be measured in 290μs, and lower data acquisition rates can be selected for high noise reduction.
