MAX6650EUB+T

Overview

The MAX6650EUB+T is a fan-speed regulator and monitor featuring an SMBus/I2C-compatible interface. It operates within a supply voltage range of 3 V to 5.5 V and supports output currents up to 50 mA with a quiescent current of 10 mA. The device functions in temperatures from -40°C to +85°C and is housed in a 10-pin uMAX package.

Feature Summary

• Integrates SMBus/I2C-compatible digital control for fan speed regulation and monitoring
• Provides low-side pre-driver outputs for direct fan control
• Supports multidrop addressing configurations for system integration

Applications

• Fan speed regulators for computer systems
• Thermal management in server infrastructure
• Motor control applications requiring digital interface

Procurement Notes

Verify the specific suffix 'EUB+T' against the manufacturer's official datasheet to confirm the 10-pin uMAX package and tape-and-reel orientation. Ensure compatibility with the target I2C/SMBus bus voltage levels and address assignments before finalizing procurement specifications.

Selection Notes

Select this component when a single-chip solution for fan speed control and thermal monitoring via a standard two-wire interface is required. Consider the 10-pin uMAX footprint constraints and the need for low-side driver capability when evaluating alternative motor controllers or dedicated fan drivers.

Part Context

This part belongs to the MAX6650 series, designed specifically for managing cooling fans in electronic equipment. It serves as a bridge between digital system controllers and analog fan loads, enabling precise thermal management through standardized communication protocols without requiring complex external circuitry.
