Flex Servo-Drives for Direct Control of Electric Motors (Stepper / BLDC / BDC)

Short Description

The HVC 4x flex servo-drive family from TDK-Micronas enables cost-effective realization of high-performance compact electric motor control. The new HVC 4422F offers extended memory size to address the OEM diagnostic requirements and allows operation in high-temperature environments. An integrated MPU supports RTOS requirements. Powered by a 32-bit CPU core (Arm® Cortex®-M3), the HVC controllers economically address growing challenges in the automotive market and beyond (industrial, consumer, instrumentation, etc.). The flexible peripherals of the product provide all means to directly control brush-type, stepper (bipolar or three phase), or brushless (BLDC) motors directly via the integrated high-performance half-bridges without the need for external driver components.

Beside timers/counters, interrupt controller, multichannel ADC, SPI, and enhanced PWMs with diagnostic functions, these devices contain an advanced LIN UART with a LIN 2.x transceiver, as well as voltage regulators to connect the device directly to an automotive board net. Various power management modes optimize current consumption. The HVC family further features a flash program memory with a size of 32 kbytes (HVC 4222/4223) or 64 kbytes (HVC 4420F/4422), providing high flexibility in code development, production ramp-up, and in-system firmware update.

Various integrated digital and analog circuit units such as comparators with virtual star point reference, current scaling and an embedded programmable gain amplifier allow users to minimize the number of external components. The computation capacity supports complex motor control algorithms such as Space Vector Modulation (SVM) for Permanent-Magnet Synchronous Motors (PMSM) in addition to six-step commutation with sensor feedback or sensorless control, as well as various stepper configurations.
