Smart Actuator Solutions for Automotive Applications
Embedded Motor Control
with HVC 422xF and HVC 442xF
Embedded Motor Control for Direct Control of Electric Motors (Stepper / BLDC / BDC)
• Enables cost-effective realization of powerful and compact DC motor control
• Economically addresses growing challenges in the automotive market and beyond (industrial, consumer, instrumentation, etc.)
• Powered by a 32-bit CPU core (Arm® Cortex®-M3) and integrating high-performance analog functions
• Flexible peripherals provide all means to directly control brush-type, stepper (bipolar or three phase), or brushless direct current (BLDC) motors via integrated high-perfor-mance half-bridges without the need for external components
• HVC 4422F offers extended memory size to address the OEM diagnostics require-ments and allows operation in high-temperature environments. An integrated memory protection unit (MPU) supports RTOS requirements.

TDK-Micronas is the center of competence for magnetic-field sensors and CMOS inte-gration within the TDK group. TDK-Micronas has gained operational excellence for sen-sors and actuators production in over 25 years of in-house manufacturing. It has been the first company to integrate a Hall-effect based sensor into CMOS technology in 1993. Since then, TDK-Micronas has shipped over five billion Hall sensors to the automotive and industrial market. The operational headquarters are located in Freiburg im Breisgau ( Germany). Currently, TDK-Micronas employs around 1,000 people.
