The STEVAL-IHM031V1 demonstration board is 
designed to drive a low voltage/low-to-medium 
current, 3-phase brushless, synchronous or 
asynchronous motor. It provides a compact 
solution along with efficient power dissipation 
thanks to dual in-package power MOSFETs.

This demonstration board integrates the following 
functional blocks: dedicated power supply for 
handling bus voltage in the range of 12 V to 24 V 
(up to 5 A), integrated gate driving, overcurrent 
protection, overvoltage and overtemperature 
sensing, three-shunt current sensing for FOC 
control, single-shunt sensing for trapezoidal 
control, BEMF sensing and amplification (for both 
GE and STMicroelectronics methods) and motor 
control connector.

The on-board MC connector allows the 
demonstration board to be interfaced with any 
STMicroelectronics MCU control board with a 
dedicated connector in order to control several 
types of 3-phase motors (asynchronous, PMSM 
brushless DC and brushless AC).
