ADBMS6822CCSZ-RL

Overview

The ADBMS6822CCSZ-RL is a dual isoSPI transceiver manufactured by Analog Devices Inc., designed for robust digital isolation in battery management systems. It operates within a supply voltage range of 1.71 V to 5.5 V and supports data rates up to 2 Mb/s. The device features bidirectional communication channels and functions across an extended temperature range from -40°C to +125°C. With a low operating power current of 12 uA, it is optimized for energy efficiency. Packaged in a QFN-32 surface-mount format, this component facilitates secure data transmission between isolated domains without requiring external isolation barriers.

Feature Summary

• Dual-channel isoSPI transceiver architecture enabling simultaneous bidirectional communication across isolation boundaries
• Integrated capacitive coupling technology providing high common-mode transient immunity for reliable signal integrity
• Ultra-low quiescent current consumption supporting extended battery life in portable and remote monitoring applications

Applications

• Battery pack monitoring systems requiring galvanic isolation between cell sensing and control circuits
• Electric vehicle (EV) and hybrid electric vehicle (HEV) battery management system interfaces
• Industrial energy storage systems with multi-cell series configurations
• Portable medical devices needing isolated data acquisition from patient-contacting sensors

Procurement Notes

Verify availability status carefully as the component may be subject to limited supply or factory special order constraints. Confirm that the specific suffix matches the required reel packaging configuration. Ensure compatibility with existing EVAL-ADBMS6822 development tools if prototyping. Check for recent product change notifications regarding manufacturing site or material updates before finalizing procurement plans.

Selection Notes

Select this component when dual-channel isolation is required for isoSPI protocol implementation. Consider the QFN-32 package dimensions for PCB layout constraints. Evaluate the 1.71 V minimum supply voltage against system power rails. Verify thermal performance requirements given the 125°C maximum operating temperature limit. Compare against single-channel alternatives if only one isolated link is necessary.
