HVC 5x

Compact Motor-Controllers for BLDC, BDC, or Stepper Motors

After having served a rapidly growing market with our popular HVC 4x fully programmable, automotive motor drivers for many years, the HVC 5x family presents an evolution from the “one size fits all” approach of their HVC 4x with a focus on smaller size, lower cost, and less external components. To increase supply robustness, the HVC 4x and HVC 5x families are sourced from two different wafer foundries.

The new HVC 5223C is focused on three-phase brushless motor applications with half the on-resistance and twice the peak current capability of the HVC 5222C.

HVC 5221D, HVC 5222C, and HVC 5223C are all 32 KB flash devices with 2 KB SRAM and 512 byte EEPROM. To maintain compatibility to the HVC 4x family, all HVC 5x devices uses the same Arm® Cortex®-M3 CPU based microcontroller with largely the same peripheral motor‑control features and LIN bus connectivity as their predecessors.

The general‑purpose I/O pins (LGPIO) have been reduced to seven and some power supply pins have been eliminated to reduce the bill of material (BOM). A WAKE input and an external reset pin have been added to increase application flexibility.

Additional features, such as differential input channels, digital timers, capture‑compare units, and an SPI master interface enable integration of application functions as well as TDK‑Micronas’ large portfolio of Hall switches or 2D/3D sensors for more precise motor control.

All current HVC 5x devices are qualified according to AEC-Q100 Grade 1, come in a thermally efficient 5 x 5 mm PQFN24 package and are pin compatible with each other as well as with future devices with higher currents and more memory.  

HVC 5x Variants
