ADBMS6822CCSZ

Overview

The ADBMS6822CCSZ 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 consumes a typical operating power supply current of 12 uA. It is housed in a QFN-32 package suitable for surface mount installation and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides dual-channel isoSPI transceiver functionality for isolated communication
• Supports bidirectional data transmission with high common-mode transient immunity
• Operates with low quiescent current consumption for energy-efficient designs

Applications

• Battery Management Systems (BMS) requiring isolated cell monitoring
• Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) battery packs
• Industrial energy storage systems with daisy-chain architectures

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'CCSZ' matches the required package and temperature grade. Request original manufacturer documentation to ensure compliance with RoHS standards and check for any recent Product Change Notifications that may affect specifications or manufacturing locations.

Selection Notes

Select this component when dual isolated isoSPI channels are required for connecting battery monitor ICs to host controllers. Ensure the system design accommodates the 1.71 V to 5.5 V supply range and the QFN-32 thermal requirements. Consider the 2 Mb/s data rate capability against the total network length and node count to maintain signal integrity within the specified temperature range.

Part Context

This part belongs to the ADBMS6822 series of digital isolators specifically engineered for battery management applications. It complements Analog Devices' portfolio of battery monitor ICs, such as the ADBMS18xx series, by providing the necessary galvanic isolation between the high-voltage battery stack and the low-voltage host processing unit.
