Overview
The US90AEVK-AAA-000-RX is a two-coil fan driver integrated circuit from Melexis, designed for brushless DC motor control. It operates within a supply voltage range of 4.7 V to 30 V and supports load voltages of 12 V and 24 V. The device provides a continuous output current of 250 mA with a fault guard (FG) feature. It functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a TO-92-4 package and is classified as Not For New Designs.
Feature Summary
- Two-coil architecture for driving brushless DC fan motors
- Integrated fault guard functionality for system protection
- Wide operating temperature range suitable for harsh environments
Applications
- Fan motor driver applications
- Brushless DC motor control systems
- HVAC cooling solutions
Procurement Notes
Verify the specific suffix RX against official Melexis documentation to confirm pinout and package configuration. Confirm lifecycle status as Not For New Designs impacts long-term availability. Ensure compatibility with existing 4.7V to 30V supply rails and 250mA load requirements before integration into new designs.
Selection Notes
Select this component for applications requiring a dedicated two-coil fan driver with fault protection. Consider the TO-92-4 through-hole package for ease of assembly where surface mount is not preferred. Evaluate the 250mA continuous current capability against the specific motor coil resistance and voltage requirements to ensure adequate drive strength without exceeding thermal limits.
Part Context
This part belongs to the US90A/US91A series of motor drivers from Melexis Technologies NV. These devices are specialized for low-power brushless DC motor applications, particularly fans. The series offers various package options including SOT-23-5 and TO-92-4 to suit different mounting and power requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Melexis directly for qualified alternatives or redesign considerations due to the Not For New Designs status.
