Smart Actuator Solutions for Automotive Applications

Embedded Motor Control

with HVC 4223F and HVC 4420F

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 4420F offers extended memory size to address the OEM diagnostics require-ments. An integrated memory protection unit (MPU) supports RTOS requirements.
