MAX31785ETL+

Overview

The MAX31785ETL+ is a six-channel intelligent fan controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating supply current of 3 mA. The device features six outputs capable of driving loads with voltages between 400 mV and 5.5 V, delivering an output current of 4 mA per channel. Designed for surface-mount installation in a TQFN-EP-40 package, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Integrates six independent intelligent fan control channels for comprehensive thermal management
Supports variable speed operation through programmable control interfaces
Includes built-in protection mechanisms against overcurrent and thermal overload conditions

Applications

Server and storage system cooling management
Telecommunications equipment thermal regulation
Industrial automation system fan control

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm RoHS compliance documentation matches the specific manufacturing batch. Validate package integrity upon receipt to ensure the exposed pad thermal connection remains undamaged during transit and handling procedures.

Selection Notes

Evaluate compatibility with existing system power rails to ensure the 2.7 V to 5.5 V input range aligns with design requirements. Assess thermal dissipation needs given the TQFN-EP-40 package footprint and exposed pad configuration. Verify that the 4 mA output current capability meets the drive requirements for the intended fan load specifications.

Part Context

This component belongs to the MAX31785 series of intelligent fan controllers designed for multi-channel thermal management applications. It serves as a specialized power management integrated circuit within the broader portfolio of motor and motion control solutions offered by the manufacturer.
