MAX6652AUB+

Thermal Management Overview

The MAX6652AUB+ 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 operates between -40°C and +125°C.

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 standard I²C-compatible and SMBus protocols with configurable address selection.

Thermal Management Applications

• Telecommunications equipment
• Desktop and notebook computers
• Workstations and servers
• Networking equipment

Thermal Management Procurement Notes

Verify the specific suffix 'AUB+' against the manufacturer's current product status to confirm availability and compliance. Ensure the selected part matches the required thermal range and package dimensions for your PCB layout. Cross-reference the datasheet revision date to confirm interface compatibility with your host controller.

Thermal Management Selection Notes

Select this component for applications requiring simultaneous monitoring of multiple low-voltage rails and thermal conditions. The device is suitable where space is constrained due to its compact 10-pin µMAX footprint. Consider the I²C/SMBus interface requirements and ensure the host system can handle the open-drain ALERT signal configuration.

Thermal Management Part Context

The MAX6652 belongs to Maxim Integrated's family of system supervisors designed for board-level monitoring. It integrates voltage sensing and thermal management into a single chip, reducing component count compared to discrete solutions. The device is engineered for reliability in industrial and commercial environments.

Thermal Management Replacement Considerations

Check for direct pin-compatible alternatives within the same series that may offer updated packaging or extended temperature ranges. Verify that any substitute maintains identical register maps and interface timing specifications to ensure software compatibility without modification.

Thermal Management FAQ

How does the MAX6652 handle address conflicts on the bus?

The device allows four different address codes by connecting the ADD pin to GND, VCC, SDA, or SCL, enabling multiple units on the same bus.

What modes are available for the temperature ALERT output?

Three modes are available: default mode, one-time interrupt mode, and comparator mode, selectable via the temperature configuration register.
