MAX6652AUB+T

Thermal Management Overview

The MAX6652AUB+T is a system supervisor and temperature sensor in a 10-pin µMAX package. It monitors four supply voltages (2.5V, 3.3V, 12V, VCC) and local temperature via an internal ADC. Operating from +2.7V to +5.5V with ±2°C accuracy at +25°C, it features programmable thresholds and an ALERT output. The device supports I²C/SMBus interfaces, offers line-frequency rejection, and includes shutdown mode.

Thermal Management Feature Summary

• Monitors multiple power-supply voltages and onboard temperature using an integrated analog-to-digital converter
• Generates latched interrupt alerts when measurements exceed user-programmable voltage or temperature limits
• Supports I²C-compatible and SMBus protocols with configurable address selection and alert response capabilities

Thermal Management Applications

• Telecommunications equipment thermal management
• Desktop and notebook computer system supervision
• Workstation and networking hardware monitoring

Thermal Management Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly processes. Confirm the ADD pin configuration matches the target I2C/SMBus address scheme. Ensure supply voltage ranges align with the +2.7V to +5.5V specification for reliable operation within the -40°C to +125°C range.

Thermal Management Selection Notes

Select this component for applications requiring simultaneous multi-voltage and temperature supervision in a compact footprint. It is suitable where I2C/SMBus compatibility is mandatory and programmable alarm thresholds are needed. Consider the 10-pin µMAX package constraints for thermal performance and board space limitations.

Thermal Management Part Context

Part of the Maxim Integrated MAX6652 series, designed for system health monitoring. It integrates voltage sensing and temperature measurement into a single supervisor IC. The device simplifies design by replacing discrete monitoring components with a unified digital interface solution for industrial and consumer electronics.

Thermal Management Replacement Considerations

Check for MAX6652 variants with different suffixes such as 'EUB' for alternative package options like uSOP. Verify electrical characteristics and pinout compatibility before substitution. Ensure any replacement maintains the same I2C/SMBus protocol support and voltage monitoring channels.
