LTC6810HG-2#3ZZPBF

LTC6810-2 is a multicell battery stack monitor. It measures upto 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 device 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. Each device has an isoSPI interface for high speed, RF-immune, long distance communications. Using the LTC6810-2, multiple devices are connected in parallel to the host processor, with each device individually addressed. It can be powered directly from the battery stack or from an isolated supply. It includes passive balancing for each cell, with PWM duty cycle control for each cell and the ability to perform redundant cell measurements. It is used in application such as electric and hybrid electric vehicles, backup battery systems, grid energy storage, high power portable equipment etc.
