TDK Expands Embedded Motor Controller Family to Target High Temperature Environments

HVC 4222F and HVC 4422F are Arm M3 based motor drivers with 32k and 64k flash memory 

TDK Corporation expanded its Micronas embedded motor controller portfolio to address higher temperature applications. The HVC 4222F and HVC 4422F were developed for operating smart actuators in applications with ambient temperature requirements up to 150 °C. HVC 4222F offers 32k flash memory while the HVC 4422F comes with 64k flash for more complex software implementations. These high temperature devices target applications in combustion vehicle drive trains and emerging thermal management systems in electric and hybrid vehicles.

Samples are available and mass production will start in Q2 of 2021.

The new high temperature devices are part of the automotive-grade, motor controller family for LIN bus connected actuators. The HVC 4xxxF family integrates an Arm standard microprocessor with six independent 500 mA half-bridge drivers and a range of additional functions to enable compact and cost-efficient motor-control applications. They are capable of driving small stepper, brushed (BDC) and brushless (BLDC) motors in applications with power requirements up to 1A peak current. 

With its processing power, the HVC family allows implementation of complex motor control algorithms such as Space Vector Modulation (SVM) for permanent magnet synchronous motors (PMSM), sensor-less commutation with back electro-magnetic force (BEMF), as well as various stepper algorithms with current limiting and stall detection. Eleven general-purpose input output pins (GPIO) enable integration of our large portfolio of hall switches or 2D/3D sensors for more precision motor control.
