HVC 4x

HVC 4x Flex Servo-Drives for Direct Control of Electric Motors (Stepper / BLDC / BDC)


 

Blockdiagram HVC 4x

Short Description

The Micronas HVC 4x flex servo-drive family was our first series of small, fully integrated motor drivers for automotive small motor applications. With over 200 million devices in the field, the HVC 4x family is the keystone of our successful, fully integrated motor control portfolio. With its six motor outputs, it represents a one-size-fits-all approach to driving all kinds of motors, as shown in the system architecture examples below.

The HVC 4x family devices are only recommended for applications requiring six motor outputs. For all other applications, we recommend considering our HVC 5x family, as these offer a lower cost and form factor, along with more power and memory options.
