LTC6811IG-1PBF规格书详情
DESCRIPTION
The LTC®6811 is a multicell battery stack monitor that
measures up to 12 series connected battery cells with
a total measurement error of less than 1.2mV. The cell
measurement range of 0V to 5V makes the LTC6811
suitable for most battery chemistries. All 12 cells can be
measured in 290μs, and lower data acquisition rates can
be selected for high noise reduction.
Multiple LTC6811 devices can be connected in series, permitting
simultaneous cell monitoring of long, high voltage
battery strings. Each LTC6811 has an isoSPI interface for
high speed, RF-immune, long distance communications.
Using the LTC6811-1, multiple devices are connected in
a daisy chain with one host processor connection for all
devices. Using the LTC6811-2, multiple devices are connected
in parallel to the host processor, with each device
individually addressed.
The LTC6811 can be powered directly from the battery
stack or from an isolated supply. The LTC6811 includes
passive balancing for each cell, with individual PWM
duty cycle control for each cell. Other features include an
onboard 5V regulator, five general purpose I/O lines and a
sleep mode, where current consumption is reduced to 4μA.
