ADBMS6830BCSWZ

Overview

The ADBMS6830BCSWZ is a 16-channel multicell battery monitor designed for high-precision applications. It measures up to 16 series-connected cells with a total measurement error of less than 2mV across the full temperature range. The device supports an operating supply voltage from 11 V to 85 V and features a built-in isoSPI interface for isolated serial communication. It includes configurable integrated low-pass filtering, hot-plug tolerance without external protection, and provisions for bus bars. The component is qualified under AEC-Q100 standards and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Built-in isoSPI interface enabling 2 Mbps isolated serial communication over a single twisted pair
• Hot-plug tolerant architecture allowing connection without external protection components
• Configurable integrated low-pass filtering for noise reduction in measurement channels
• Stackable architecture supporting high-voltage battery pack configurations

Applications

• Electric and hybrid vehicles
• Backup battery systems
• Grid energy storage

Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with your design requirements. Confirm AEC-Q100 qualification status if automotive compliance is mandatory. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when high accuracy across a wide temperature range is required for multi-cell battery monitoring. Ensure the system design accommodates the 11 V to 85 V operating voltage range. Consider the stackable architecture if scaling beyond 16 cells is necessary. Verify that the LQFP-80 EP package fits the available PCB space.
