Figure 1 EVAL-ISOMAX Dual isoSPI Adapter

The EVAL-ISOMAX is an integrated dual isoSPI adapter and microcontroller board featuring the MAX32670 high-reliability, ultra-low-power microcontroller and the ADBMS6822 dual isoSPI transceiver. This board allows multiple ADBMS68xx battery monitors to be connected through daisy chain configuration. The EVAL-ISOMAX also features reversible isoSPI, which enables a redundant path to the peripheral units. The PCB components and DuraClik connectors are optimized for low electromagnetic interference (EMI) susceptibility and emissions.

Use Cases

The EVAL-ISOMAX has an on-board ultralow-power Arm-Cortex M4-based MCU that is suitable for broad market applications such as for IoT and industrial battery management systems. The EVAL-ISOMAX board is recommended to be used with other ADI broad market BMS boards such as the EVAL-ADBMS6830BMSW battery stack monitor and the EVAL-ADBMS2950-BASIC pack monitor.

Users may also opt to use other microcontrollers for other applications requiring more stringent timing, higher memory, or faster computing speed. Other possible microcontrollers to be paired are the SDP-K1 and AD-APARD32690-SL .

Option 1: Using the EVAL-ISOMAX as Standalone MCU with other ADI Broad Market BMS Boards
