TDK Corporation has expanded its Micronas embedded motor controller portfolio with the first members of the new HVC 5x family of programmable system-on-chip (SOC) motor controllers for driving small stepper, brushed (BDC) and brushless (BLDC) motors in automotive and industrial applications. FOC Control Motor For Fan

The new HVC 5x family represents an application-specific evolution of the popular HVC 4x devices which were intended as a “one IC fits all” motor-control solution for stepper, BLDC and BDC motors. The new HVC 5221D and HVC 5222C are focused on individual motor types to enable lower-cost and smaller-form-factor applications. Samples are already available, start of production is planned for the beginning of 2024.

With the HVC 4x and the first two devices of the HVC 5x family, TDK is offering an ever-increasing portfolio of motor-control solutions for smart actuators with a specific focus on thermal systems in electric and hybrid vehicles. The HVC 5221D includes four motor terminals with a peak current of 500 mA each, focusing on stepper and DC motors in expansion and water valves.

The HVC 5222C has three motor terminals, making it suitable for brushless motors with up to 1 A phase current for grille shutters and small fans. Both devices include seven general-purpose I/O ports and many automotive diagnostic and safety features in small form-factor 24-pin QFN package. All HVC 5x controllers are pin compatible for easier design and scalability.
