Overview
The MAX6651EEE+ is a fan-speed regulator and monitor featuring an SMBus/I2C-compatible interface, housed in a 16-pin QSOP package. 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. Designed for surface-mount installation, it integrates control logic for managing cooling systems while providing necessary monitoring capabilities through its serial communication protocol.
Feature Summary
- Integrates SMBus and I2C-compatible serial interface for system communication
- Provides dedicated fan speed regulation and operational monitoring
- Supports surface-mount installation in compact QSOP-16 packages
Applications
- Computer system thermal management
- Server chassis cooling control
- Industrial equipment ventilation regulation
Procurement Notes
Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt as the device utilizes sensitive surface-mount construction. Ensure compatibility with existing SMBus or I2C bus architectures before integration into final designs. Review manufacturer documentation for specific handling requirements related to electrostatic discharge protection during assembly processes.
Selection Notes
Evaluate system requirements against the specified 3 V to 5.5 V operating voltage window to ensure proper functionality. Consider the 16-pin QSOP footprint constraints when designing printed circuit board layouts. Assess thermal performance needs relative to the -40°C to +85°C operating temperature range. Verify that the 50 mA output capability meets the load requirements of connected cooling fans without exceeding electrical limits.
Part Context
This component belongs to the MAX6651 series of power management integrated circuits manufactured by Analog Devices Inc./Maxim Integrated. The series focuses on thermal management solutions utilizing serial communication protocols. The MAX6651 variant specifically addresses fan control applications requiring precise speed regulation and status monitoring within electronic systems.
Replacement Considerations
Consult official manufacturer substitution guides for verified alternative part numbers. Cross-reference pin configurations and electrical specifications before implementing any replacement components. Ensure functional equivalence regarding serial interface compatibility and thermal operating ranges.
