MAX17823BGCB/V+

Overview

The MAX17823BGCB/V+ is a specialized high-voltage data acquisition system designed for battery management applications. It integrates twelve channels for cell voltage measurement and two channels for temperature sensing within a single LQFP-64 package. The device supports a wide operating voltage range from 9V to 65V, enabling direct monitoring of series-connected lithium-ion cells in modules up to 65V. It features a 12-bit SAR ADC with selectable oversampling for enhanced resolution, passive balancing switches, and comprehensive diagnostic capabilities including thermal shutdown.

Feature Summary

• Integrates twelve high-voltage measurement channels and two temperature inputs for complete module monitoring
• Supports UART daisy-chain communication for scalable multi-device systems managing up to 384 cells
• Includes internal passive balancing switches with emergency discharge functionality for cell equalization
• Provides extensive built-in diagnostics and fault protection mechanisms compliant with automotive safety standards

Applications

• Electric vehicle (EV) battery modules
• Hybrid electric vehicle (HEV) power packs
• Uninterruptible power supply (UPS) battery backups
• Large-scale energy storage systems
• High-voltage battery packs for industrial equipment

Procurement Notes

Verify the specific suffix 'BGCB' against official Analog Devices documentation to confirm pinout and feature set. Confirm AEC-Q100 Grade 2 qualification status if automotive compliance is required. Check current availability as distribution may be limited or subject to factory order constraints. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this component when designing battery modules requiring up to twelve series cells per unit. Consider the 65V common-mode range for compatibility with standard 400V platform architectures. Evaluate the UART interface requirements against the host controller's available ports. Assess the need for integrated balancing versus external solutions based on thermal management constraints.

Part Context

This part belongs to the Maxim Integrated MAX17823 family of battery monitor ICs. It is engineered for high-reliability applications in electrified transportation and stationary storage. The device replaces discrete monitoring solutions by integrating analog front-end, digital control, and communication interfaces into a compact surface-mount package.

Replacement Considerations

Consult official cross-reference lists for compatible alternatives such as the MAX17823HGCB/V+T or other members of the MAX1782x series. Verify functional equivalence regarding channel count, voltage ratings, and communication protocols before substitution.
