MAX6650EUB

Overview

The MAX6650EUB+T is a fan-speed regulator and monitor featuring an I2C-compatible interface. It operates within a supply voltage range of 3V to 5.5V and supports brushless DC (BLDC) motors. The device provides low-side pre-driver outputs with a maximum output current of 50 mA. It functions as a speed controller suitable for applications requiring precise thermal management. The component is housed in a 10-uMAX/uSOP surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

Integrates SMBus/I2C-compatible interface for digital control
Provides low-side pre-driver outputs for motor drive
Supports speed regulation for brushless DC fans

Applications

Fan controllers
Thermal management systems
Server and storage cooling

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated, as ownership transitions may affect documentation sources. Ensure the part number aligns with RoHS3 compliance requirements if specified by the design. Cross-reference the EDA/CAD model with the exact package dimensions for PCB layout accuracy.

Selection Notes

Select this component for designs requiring I2C-controlled BLDC fan regulation. Verify that the system power supply falls within the 3V to 5.5V operating range. Ensure the application utilizes low-side switching compatible with the pre-driver outputs. Check that the 10-pin uMAX package fits the available board space. Confirm compatibility with the host controller's I2C bus voltage levels.

Part Context

This part belongs to the MAX6650/MAX6651 family of fan controllers. These devices are designed for multidrop address assignments and thermal monitoring. The series supports both 24V and 48V fan speeds regulators. Documentation includes guides on using these components for efficient thermal management in electronic systems.
