MAX11080IUU+T

Overview

The MAX11080IUU+T is a 12-channel, high-voltage battery-pack fault monitor designed for lithium-ion battery management systems. It operates within a wide supply voltage range of 6 V to 72 V and provides a regulated 3.3 V output with a maximum current capability of 50 mA. The device features an extremely low operating supply current of 50 nA, enhancing energy efficiency in portable applications. Packaged in a TSSOP-38 surface-mount format, it integrates monitoring capabilities for high-voltage battery packs.

Feature Summary

• Monitors up to twelve channels for fault detection in high-voltage battery configurations
• Supports operation across a wide input voltage spectrum suitable for multi-cell stacks
• Integrates a low-power regulator to provide stable auxiliary power

Applications

• Lithium-ion battery pack protection circuits
• High-voltage battery management system (BMS) fault monitoring
• Portable electronic devices requiring multi-cell battery supervision

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'T' indicates tape-and-reel packaging configuration. Request official datasheets and compliance documentation to ensure alignment with project specifications. Validate that the TSSOP-38 package matches the design footprint requirements prior to procurement.

Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple high-voltage cells. Ensure the application voltage does not exceed the 72 V maximum limit. Consider the 50 nA quiescent current for battery life optimization. Verify that the TSSOP-38 package dimensions fit the available PCB space and thermal constraints.

Part Context

This part belongs to the MAX11080 series, which focuses on battery protection and monitoring. It serves as a specialized interface between high-voltage battery stacks and lower-voltage control logic. The device simplifies BMS design by integrating multiple monitoring functions into a single compact package, reducing component count and board space.

Replacement Considerations

Consult Analog Devices discontinuation notices for legacy status updates. Identify alternative monitors within the MAX1108x family if pin compatibility is required. Verify functional equivalence regarding channel count and voltage ranges before substituting.
