ADBMS6817WCSWZ

Overview

The ADBMS6817WCSWZ is an 8-channel multicell battery stack monitor designed for measuring series-connected battery cells. It supports a cell measurement range of 0 V to 5 V, accommodating most common battery chemistries. The device features integrated high-voltage switches and analog-to-digital converters (ADCs) for direct cell voltage monitoring. Communication with the host microcontroller is facilitated via standard SPI or I2C interfaces. All eight cells can be measured within 304 µs, enabling rapid state-of-charge calculations in demanding applications.

Feature Summary

• Integrated high-voltage switches and ADCs for direct cell voltage monitoring
• Supports standard SPI and I2C communication interfaces
• Capable of measuring all eight cells within 304 µs

Applications

• Electric vehicle battery management systems
• Hybrid electric vehicle powertrains
• Uninterruptible power supply (UPS) stacks
• Energy storage system monitoring

Procurement Notes

Verify the specific suffix WCSWZ against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as distribution channels may list limited stock or discontinued variants. Ensure the ordering part number matches the required pinout and thermal pad configuration for your PCB layout.

Selection Notes

Select this component when monitoring up to eight series-connected cells is required. It is suitable for multi-chemistry battery packs operating within the 0 V to 5 V per cell range. Consider the 304 µs conversion time for applications requiring fast state estimation. Verify interface compatibility with the host controller's SPI or I2C capabilities.

Part Context

This device belongs to the Analog Devices multicell battery monitor family, which includes variants like the ADBMS6816 and ADBMS6815. These components are engineered for high-reliability battery stack monitoring in automotive and industrial sectors. The ADBMS6817 specifically targets 8-cell configurations, offering a balance between channel count and conversion speed.

Replacement Considerations

Check for ADBMS6816M or ADBMS6815M equivalents if channel count requirements differ. Verify pin compatibility before substituting with other 8-channel monitors from different manufacturers.
