Overview
The MAX6650EUB+T is a fan speed regulator and monitor manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 5.5V and supports I2C interface communication. The device features a low-side pre-driver output configuration and is designed for brushless DC (BLDC) motors. It is housed in a 10-uMAX/uSOP package with dimensions of 0.118 inches (3.00mm) width. The component functions as a speed controller and is rated for an operating temperature range from -40°C to +85°C.
Feature Summary
- Supports SMBus/I2C-compatible interface for digital control
- Integrated low-side pre-driver for motor control
- Designed for fan speed regulation and monitoring applications
Applications
- Fan controllers
- Brushless DC motor speed regulation
- Thermal management systems
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'E' grade corresponds to the industrial temperature range requirements. Ensure the 10-uMAX package footprint matches the target PCB design. Check RoHS compliance status against current environmental regulations. Validate the I2C address settings if multiple devices are used on the same bus.
Selection Notes
Select this component for applications requiring precise fan speed control via digital interfaces. Consider the 3V to 5.5V supply range compatibility with system power rails. Evaluate the 10-pin package size for space-constrained designs. Verify that the low-side driver architecture suits the motor load configuration. Assess thermal performance within the specified operating temperature limits.
Part Context
The MAX6650 belongs to the MAX6650/MAX6651 family of fan-speed regulators. These devices integrate monitoring capabilities alongside speed control functions. The EUB variant specifically denotes the industrial temperature grade and the 10-lead ultra-small outline package. This series is commonly used in computer and server cooling solutions.
Replacement Considerations
The MAX6651 is a related model within the same family offering similar functionality. Verify pinout compatibility and software register mapping before substitution. Check if the alternative part number meets the specific temperature and voltage requirements.
