TDA21801XUMA1

Overview

The TDA21801XUMA1 is a low-cost fan speed controller manufactured by Infineon Technologies. It is designed for driving DC fans with a supply voltage range of 10.8V to 13.2V. The component utilizes a PDSO-8 package and operates within an ambient temperature range of 0°C to 70°C. It is suitable for surface mount applications in consumer electronics requiring simple fan control.

Feature Summary

• Integrated circuit architecture optimized for direct DC fan drive
• Low-cost design solution for basic speed regulation
• Surface-mount compatible packaging for automated assembly

Applications

• Consumer electronics cooling systems
• Appliance fan speed control
• General purpose DC motor ventilation

Procurement Notes

Verify the specific operating temperature range requirements against the 0°C to 70°C specification. Confirm that the 10.8V to 13.2V supply voltage aligns with the system design. Ensure the PDSO-8 footprint matches the PCB layout. Check for any updated revisions or alternative packages if higher thermal performance is needed.

Selection Notes

Select this component for applications requiring simple, cost-effective fan control without complex PWM features. It is suitable for environments where the ambient temperature remains within 0°C to 70°C. Consider the limited voltage range and ensure it fits the 12V nominal system architecture. Evaluate if the basic control functionality meets the application needs compared to more advanced controllers.

Part Context

The TDA21801 belongs to Infineon's portfolio of analog and mixed-signal power management solutions. It serves as a dedicated driver for small DC motors, primarily fans. The device simplifies design by integrating necessary drive components into a compact 8-pin package, reducing bill of materials count for basic ventilation tasks.
