MAX11081GUU+T

Overview

The MAX11081GUU+T is a battery management integrated circuit designed for lithium-ion battery systems. It functions as a battery monitor supporting configurations of one to twelve cells. The device operates within an extended temperature range from -40°C to +105°C and utilizes a 38-TSSOP surface-mount package. Key electrical specifications include a maximum output voltage of 3.3 V and compliance with AEC-Q100 automotive qualification standards. It incorporates overvoltage and undervoltage fault protection mechanisms to ensure system reliability.

Feature Summary

• Supports monitoring of single-cell to twelve-cell lithium-ion battery stacks
• Includes hardware-based overvoltage and undervoltage fault protection
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive battery management systems
• Lithium-ion battery pack monitoring
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm package integrity and pin alignment against the 38-TSSOP specification. Ensure environmental compliance documentation matches current regulatory requirements. Validate that the specific suffix corresponds to the tape-and-reel packaging format required for automated assembly processes.

Selection Notes

Select this component when designing systems requiring multi-cell lithium-ion battery supervision with automotive-grade reliability. Consider the 38-pin interface complexity and thermal performance limits up to 105°C during operation. Evaluate the necessity for integrated fault protection features versus external monitoring solutions based on board space constraints.
