ADBMS2950B

• Fully-featured evaluation board for the ADBMS2950B
• Bidirectional high-accuracy current measurement with on board shunt
• Increased input-range overcurrent measurement and alert
  • Battery stack measurements
  • Battery stack voltage monitoring
  • Isolation measurement
  • Precharge monitoring
  • Fuse monitoring
  • Charger monitoring
  • Link voltage monitoring
• Includes two isoSPI ports for daisy chain and reversible isoSPI support, and the isoSPI connections can be done through simple DuraClick™ connectors

The EVAL-ADBMS2950B evaluation board features the ADBMS2950B, a bidirectional current monitor, with 12 buffered high-impedance voltage sense inputs, linked through a 2-wire isolated serial interface (isoSPI). The demo circuit also features reversible isoSPI, which enables a redundant communication path.

The EVAL-ADBMS2950B can communicate to a PC over isoSPI by attaching a EVAL-ADBMS6822 dual-controller isoSPI add-on board to the expansion headers of a EVAL-SDP-CK1Z, and then connecting the EVAL-SDP-CK1Z to a host PC through USB.

The EVAL-ADBMS2950B evaluation board can be operated on the same isoSPI daisy chain with other ADBMS2950B, and ADBMS6830B devices.

Full specifications on the ADBMS2950B are available in the ADBMS2950B data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVALADBMS2950B evaluation board.

Design files for this circuit board are available on the product webpage.

The AD-CELLPACKBM-SL is a complete BMS kit consisting of the EVAL-ADBMS6830BMSW 16-channel cell monitoring module, the EVAL-ADBMS2950-BASIC pack monitoring module, EVAL-ADBMS6822 isoSPI adapter, and a microcontroller board.​

The AD-CELLPACKBM-SL can operate either in embedded mode or through a PC-based graphical user interface. Complete with working software and hardware, as well as software examples, this kit makes it easier for customers to prototype and create connected systems and solutions for BMS applications.​

This package comes with the SDP-K1 as its MCU module, but the BMS components included in this kit are also compatible for use with other controller boards such as the AD-APARD32690-SL or MAX32690EVKIT.​
