The ADBMS6830B is a multicell battery stack monitor that measures up to 16 series-connected battery cells with a lifetime total measurement error (TME) of less than 2 mV over the full temperature range. The measurement input range of −2 V to +5.5 V makes the ADBMS6830B suitable for most battery chemistries and allows the measurement of voltages across bus bars. Provisions are made for bypassing bus bars without dedicating any measurement channels.

All cells can be measured simultaneously and redundantly with two individual analog-to-digital converters (ADCs). The continuously operating ADCs with a high sampling rate of 4.096 MHz allow reduced external analog filtering and aliasing-free measurement results. Higher noise reduction can be achieved by subsequent programmable infinite impulse response (IIR) filters.

Multiple ADBMS6830Bs can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each ADBMS6830B has an isolated serial port interface (isoSPI™) for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection. This daisy chain can be operated bidirectionally, ensuring communication integrity even in the event of a fault along the communication path.

The ADBMS6830B can be powered from the battery stack or an isolated supply. The ADBMS6830B includes passive balancing with individual pulse-width modulation (PWM) duty cycle control and up to 300 mA discharge current for each cell. Other features include an on-board 5 V regulator, up to 10 GPIOs, and a sleep mode, where current consumption is reduced to 4 μA.

Product Detail

The EVAL-ADBMS6830BMSW is a full-featured evaluation board for the ADBMS6830B, a 16-channel battery stack monitor for broad market applications. This board allows multiple boards to be linked through a single twisted pair wire interface (isoSPI) to monitor a long series of cells in a stack. It provides access to full channel monitoring to all cells going to battery pack either in the supply line or in the V+ to V- line. The evaluation board also features reversible isoSPi that can access either path to do measurement functions and serve as a redundant communication path. The PCB, components, and DuraClik connectors are optimized for low EMI susceptibility and emissions.
