MAX6651EEE+T

Overview

The MAX6651EEE+T is a fan speed regulator and monitor featuring an SMBus/I2C-compatible interface. It operates within a supply voltage range of 3V to 5.5V and supports both local and remote temperature sensing configurations. The device integrates programmable thermal shutdown, overtemperature alarms, and tachometer inputs for brushless DC fans. Packaged in a 16-pin QSOP, it functions as a comprehensive thermal management solution for system cooling applications.

Feature Summary

• Integrates SMBus/I2C-compatible interface for digital control and monitoring
• Supports local and remote temperature sensing with programmable thresholds
• Provides tachometer input functionality for brushless DC fan speed monitoring

Applications

• Fan speed regulators and monitors
• Thermal management systems
• Motor drivers and controllers

Procurement Notes

Verify the specific suffix EEE+T against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing SMBus or I2C bus architectures before integration. Confirm that the lead time and availability status align with project requirements, as distribution channels may vary.

Selection Notes

Select this component when precise digital control of fan speed via SMBus or I2C is required alongside integrated temperature monitoring. It is suitable for designs needing both local and remote thermal sensing capabilities within a single IC. Consider the 16-pin QSOP package constraints and operating temperature range during PCB layout.
