MAX31790ATI+T

Overview

The MAX31790ATI+T is a six-channel PWM-output fan RPM controller manufactured by Analog Devices Inc./Maxim Integrated. It controls up to six fans using independent PWM outputs, with desired speeds written via an I2C interface. The device features six dedicated tachometer inputs for precise RPM monitoring and failure detection, plus the ability to configure any PWM output as a tachometer input. Operating on a 3.0V to 5.5V supply, it supports a -40°C to +125°C temperature range in a 28-pin TQFN package.

Feature Summary

Controls up to six independent fans with direct PWM drive
Provides precise RPM monitoring through dedicated tachometer inputs
Ensures reliable startup configurations without system microcontroller intervention
Features controlled duty cycle rate-of-change for optimal acoustics

Applications

Server cooling systems
Networking equipment thermal management
Telecom infrastructure cooling

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the 28-pin TQFN specification. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference ordering information with official datasheets to validate suffix designations and regional availability constraints.

Selection Notes

Select this component for applications requiring multi-fan control with high precision. Evaluate compatibility with I2C bus interfaces and system voltage levels within the 3.0V to 5.5V range. Consider thermal dissipation capabilities in the TQFN package for enclosed environments. Verify that the number of required tachometer inputs aligns with the device's six dedicated pins plus configurable options.
