Overview
The MAX6651EEE+ 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 typical operating current of 10 mA. The device functions reliably across an extended temperature range from -40°C to +85°C. Housed in a 16-pin QSOP package, it integrates thermal management capabilities for system cooling applications.
Feature Summary
- Integrates SMBus and I2C-compatible digital interfaces for system control
- Provides programmable fan speed regulation and thermal monitoring
- Supports low-voltage operation suitable for portable systems
Applications
- Fan speed control in computer motherboards
- Thermal management in telecommunications equipment
- System cooling in industrial embedded controllers
Procurement Notes
Verify the specific suffix against official documentation to confirm pinout compatibility and electrical characteristics. Confirm availability status as distribution channels may list limited stock or obsolete inventory. Ensure the selected variant matches the required package type and temperature rating for the target application environment.
Selection Notes
Select this component when integrated SMBus or I2C communication is required for fan control. Verify that the 16-pin QSOP package fits the PCB layout constraints. Ensure the 3 V to 5.5 V supply range aligns with the system power architecture and that the -40°C to +85°C operating range meets environmental requirements.
Part Context
This part belongs to the MAX6651 series of fan controllers developed by Analog Devices / Maxim Integrated. It is designed specifically for managing cooling fans in electronic systems requiring digital interface control. The series focuses on providing reliable thermal regulation through standardized communication protocols.
Replacement Considerations
Consult official datasheets for direct pin-to-pin replacements within the same family. Verify functional equivalence regarding interface protocol and voltage specifications before substitution.
