MAX31785AETL+

Overview

The MAX31785AETL+ is a six-channel intelligent fan controller designed for closed-loop thermal management. It operates on a supply voltage range of 2.7 V to 5.5 V with an operating supply current of 3 mA and output current of 4 mA per channel. The device supports load voltages from 400 mV to 5.5 V and functions within a temperature range of -40°C to +85°C. Packaged in a 40-pin TQFN-EP-40 surface-mount format, it integrates automatic closed-loop control to optimize system power efficiency by adjusting fan speeds based on thermal requirements.

Feature Summary

Integrates six independent channels for simultaneous multi-fan control
Implements automatic closed-loop regulation to maintain target temperatures
Optimizes system power consumption by dynamically adjusting fan operation

Applications

Server and storage enclosure thermal management
Telecommunications equipment cooling systems
Industrial control panel ventilation

Procurement Notes

Verify the specific suffix 'A' against the required temperature grade and pinout configuration. Confirm the 40-WFQFN package dimensions match the PCB footprint. Ensure the 2.7 V to 5.5 V supply range aligns with the system power architecture. Check for RoHS compliance documentation if environmental regulations apply.

Selection Notes

Select this component when precise closed-loop control of multiple fans is required. It is suitable for applications needing low standby current and wide input voltage flexibility. Consider the TQFN-EP-40 package for compact designs requiring efficient heat dissipation through the exposed pad.

Part Context

This part belongs to the MAX31785 series of intelligent fan controllers. It serves as a specialized power management IC for motor and motion control applications. The device replaces discrete control circuits by integrating multiple driver channels into a single compact solution.
