LTC6810HG-1#3ZZPBF

LTC6810-1 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. Multiple LTC6810-1 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each device 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 devices. It supports bidirectional operation, allowing communication even with a broken wire. It is widely used in application such as electric and hybrid electric vehicles, backup battery systems, grid energy storage, high power portable equipment etc.
