MAX6620ATI+

Overview

The MAX6620ATI+T is a quad linear fan speed controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3 V to 5.5 V and features an I²C-compatible serial interface for digital control. The device is housed in a 28-TQFN package measuring 5x5 mm. It provides four independent output channels with a maximum output current of 3 mA per channel, suitable for driving small fans or similar loads.

Feature Summary

• Quad linear fan speed control capability
• I²C-compatible serial interface for digital communication
• Surface-mount TQFN package design

Applications

• Computer system thermal management
• Server chassis cooling control
• Consumer electronics ventilation systems

Procurement Notes

Verify the specific suffix (e.g., +T) against official datasheets to confirm packaging type and RoHS compliance status. Ensure the source document explicitly identifies the manufacturer as Analog Devices Inc. or Maxim Integrated. Confirm the package dimensions match the 28-TQFN specification before procurement.

Selection Notes

Select this component when a multi-channel, digitally controlled fan solution is required. The I²C interface allows for simplified wiring compared to PWM controllers. Verify that the load current requirements do not exceed the 3 mA per channel limit specified in the official documentation.

Part Context

This part belongs to the Maxim Integrated motor and motion controller family. It is distinct from temperature sensors like the DS1620 or power management ICs like the MAX8662. The MAX6620 series focuses specifically on linear fan speed regulation rather than switching or sensing functions.

Replacement Considerations
