MAX11080GUU+T

Overview

The MAX11080GUU+T is a high-voltage battery-pack fault monitor designed for multi-cell lithium-ion battery systems. It integrates twelve channels of voltage measurement with an internal analog-to-digital converter, enabling comprehensive monitoring of series-connected battery packs. The device supports communication via SMBus or I2C interfaces and includes features for overvoltage and undervoltage detection. It operates within a wide supply voltage range and is packaged in a compact TSSOP format suitable for space-constrained automotive and industrial applications.

Feature Summary

• Integrates twelve high-voltage input channels for simultaneous cell voltage monitoring
• Includes internal fault detection logic for overvoltage and undervoltage conditions
• Supports serial communication through SMBus or I2C compatible interfaces
• Features low standby current consumption for energy-efficient operation

Applications

• Electric vehicle battery management systems
• Hybrid electric vehicle powertrain control
• Industrial battery storage units

Procurement Notes

Verify the specific suffix 'GUU+T' to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance and AEC-Q100 qualification if required for automotive use. Check current lifecycle status as availability may be limited due to production phase changes. Ensure compatibility with existing PCB footprints and communication protocols before finalizing procurement.

Selection Notes

Select this component when monitoring twelve series-connected cells is required without external multiplexers. Consider the operating temperature range and package size constraints. Evaluate the need for integrated fault protection versus external circuitry. Compare performance metrics against alternative monitors regarding accuracy and speed requirements for the specific application.
