MAX17823BGCB/V+T

Overview

The MAX17823BGCB/V+T is a high-voltage battery management integrated circuit designed for monitoring and balancing up to twelve series-connected lithium-ion cells. It features a 12-bit SAR ADC with a 65V common-mode range, enabling precise voltage measurement across the stack. The device integrates passive balancing switches capable of delivering up to 650mA per channel. It supports UART communication in a daisy-chain topology, allowing multiple units to manage extensive battery arrays while maintaining low standby current consumption.

Feature Summary

• Integrates twelve internal switches for passive cell balancing with high current capability
• Supports daisy-chain connectivity for scalable multi-device battery system architectures
• Includes comprehensive built-in diagnostic functions for fault detection and thermal protection

Applications

• Electric vehicle (EV) battery packs
• Hybrid electric vehicle (HEV) modules
• Uninterruptible power supply (UPS) systems
• High-voltage battery storage systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to potential counterfeit risks. Confirm specific suffix variations against official datasheets as they may indicate distinct temperature grades or packaging formats. Ensure compatibility with existing UART protocols and validate electrical specifications against the target application requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high-voltage isolation and precise multi-cell monitoring within a single package. Evaluate the balance between the integrated balancing current capabilities and the required thermal management infrastructure. Consider the UART interface constraints and daisy-chain limitations when designing the system architecture for scalability and communication reliability.

Part Context

This part belongs to the Maxim Integrated battery management family, now under Analog Devices. It serves as a specialized data acquisition system for high-voltage environments. The device replaces older discrete solutions by integrating ADC, balancing, and communication interfaces into a compact LQFP package, simplifying PCB layout and reducing overall system component count.

Replacement Considerations

Consider the MAX17823HGCB/V+T for alternative grade variants. Verify functional equivalence with other members of the MAX17823 series if pinout compatibility is required.
