Next-gen embedded motor controller family for SoC BDC and BLDC

TDK Corporation expands its Micronas embedded motor controller portfolio with the first members of the new HVC 5x family of programmable SoC motor controllers for driving small stepper, BDC and BLDC motors in automotive and industrial applications. The new family provides an application-specific evolution of the popular HVC 4x devices, which were planned as a 'one IC fits all' motor-control solution for stepper, BLDC and BDC motors. The new HVC 5221D and HVC 5222C target individual motor types, allowing lower-cost and smaller-form-factor applications.

With the HVC 4x and the first two devices of the HVC 5x family, the company is providing an ever-growing portfolio of motor-control solutions for smart actuators with a distinct focus on thermal systems in EV and HEV. The HVC 5221D comprises four motor terminals with a peak current of 500mA each, aimed at stepper and DC motors in expansion and water valves. The HVC 5222C offers three motor terminals, making it ideal for brushless motors with up to 1A phase current for grille shutters and small fans. Both devices incorporate seven general-purpose I/O ports and many automotive diagnostic and safety features in a small form-factor 24-pin QFN package. All HVC 5x controllers are pin compatible for simpler design and scalability.
