Overview
The US90AEDC-AAA-000-RE is a two-coil fan driver manufactured by Melexis Technologies NV. It functions as a brushless DC motor controller designed for driving fan motors. The device operates within a supply voltage range of 4.7V to 30V and provides a continuous output current capability of 250mA. It is housed in an SOIC-8 package with a leaded (FG) termination style. The component supports industrial temperature ranges, typically spanning from -40°C to +85°C.
Feature Summary
- Integrated two-coil driver architecture specifically optimized for fan motor applications
- Full integration of control logic and power stage for simplified design
- Supports operation across a wide supply voltage range suitable for various system rails
Applications
- Brushless DC fan motor control
- Thermal management systems requiring two-coil drive topology
- Industrial cooling fans
Procurement Notes
This component is listed as obsolete or not recommended for new designs. Availability is restricted, and verification of current stock status with authorized distributors is essential before procurement planning. Ensure that the specific suffix matches the required packaging format, as variations may exist for legacy inventory.
Selection Notes
Select this part only if the application strictly requires a two-coil BLDC fan driver topology. Verify that the 250mA continuous current rating meets the load requirements. Consider that the device is end-of-life; alternative newer generations from the manufacturer should be evaluated for long-term supply security and updated feature sets.
Part Context
The US90AEDC belongs to the US90A/US91A series of motor drivers from Melexis. These devices are designed for low-cost, high-volume fan applications. The specific 'EDC' suffix indicates the package type and tape/reel packaging configuration. This series represents a specialized solution for simple fan control without complex sensor feedback requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, consult Melexis directly for official obsolescence notices and recommended replacement families.
