Overview
The MLX90297KZC-VAF-108-RX is a single-coil fan driver IC from Melexis, designed for PWM control of DC fans. It operates within a supply voltage range of 3.3V to 18V and features an 800mA current limit. The device supports operating frequencies from 100Hz to 100kHz and includes configurable speed curves. It is housed in an 8-pin SOIC package with flat leads and holds AEC-Q100 qualification for automotive reliability.
Feature Summary
- Configurable speed curve for precise fan control
- Low noise operation suitable for consumer applications
- Integrated fan-off functionality
Applications
- Single coil DC fan control
- Consumer electronics cooling systems
- Automotive ventilation modules
Procurement Notes
Verify the suffix 'RX' indicates tape and reel packaging versus 'SP' which may denote spool or cut tape. Confirm AEC-Q100 qualification status for automotive use cases. Check for end-of-life notifications as related variants are marked NRND. Ensure compatibility with 8-SOIC footprint requirements.
Selection Notes
Select this component for applications requiring a single-coil driver with integrated PWM capability. The 800mA limit suits small to medium fans. Consider the SOIC-8 package for surface mount assembly. Verify input voltage ranges match the system's 3.3V to 18V requirement.
Part Context
This part belongs to the MLX90297 series of motor controllers. It is specifically engineered for single-coil fan drivers. The series offers various packages and configurations. This specific model focuses on low-noise performance and configurable speed characteristics for quiet operation.
Replacement Considerations
MLX90297KZC-VAF-108-SP is a similar variant with potential packaging differences. Verify pinout and electrical specifications before substitution. Other MLX90297 models may offer different packages like UDFN.
