MAX6615AEE+T

Thermal Management Overview

The MAX6615AEE+T is a dual-channel temperature monitor and fan-speed controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0V to 5.5V and supports an operating temperature range from -40°C to +125°C. The device features two thermistor inputs for external temperature sensing and includes a local internal die temperature sensor. It utilizes a 2-wire SMBus/I²C-compatible serial interface for communication, allowing access to temperature data and programmable alarm thresholds. The unit consumes 500µA of typical supply current.

Thermal Management Feature Summary

• Monitors two temperature channels using either the internal die or external thermistors
• Generates PWM output signals to control cooling fan speed based on thermal conditions
• Includes overtemperature alarm outputs for system shutdown or throttling
• Features fan-fail detection via tachometer signal monitoring

Thermal Management Applications

• Desktop Computers
• Servers
• Power Supplies
• Networking Equipment
• Workstations

Thermal Management Procurement Notes

Verify that the specific suffix 'T' corresponds to tape-and-reel packaging if required by assembly equipment, as datasheet ordering information lists the MAX6615AEE in tube packaging. Confirm the manufacturer designation matches Analog Devices Inc./Maxim Integrated specifications. Ensure the component meets RoHS compliance requirements for the intended deployment environment.

Thermal Management Selection Notes

Select this component when dual-channel thermal monitoring with integrated fan control is necessary. It is suitable for systems requiring SMBus connectivity and low power consumption. Consider the MAX6616 variant if additional GPIO flexibility is needed, noting it uses a 24-pin package compared to the 16-pin QSOP used by the MAX6615.

Thermal Management Part Context

This part belongs to the MAX6615/MAX6616 series of dual-channel temperature monitors and fan-speed controllers. These devices are designed to minimize acoustic noise by adjusting fan speeds dynamically while ensuring maximum cooling during high power dissipation events. They integrate digital interfaces and fail-safe protection mechanisms for robust thermal management.

Thermal Management Replacement Considerations

MAX6616AEG serves as a functional alternative within the same family, offering six GPIOs and a 24-pin QSOP package instead of the 16-pin configuration.
