The STEVAL-IFN004V1 demonstration board is 
based on STMicroelectronics’ STM8S105 
microcontroller and the DMOS fully integrated 
three-phase motor driver L6230 implementing 
6-step scalar control of a BLDC motor.

The board is designed as an evaluation 
environment for motor control applications in the 
range of 8 V - 48 V of DC bus voltage and up to 
35 W, exploiting the embedded features of the 
STM8S105. This microcontroller includes internal 
2 KB SRAM and 128 KB Flash, and SWD 
debugging.  The L6230 DMOS driver features 
2.8 A output peak current, non-dissipative 
overcurrent detection/protection, cross-
conduction protection, internal comparator used 
for cycle-by-cycle current limitation/regulation, 
thermal shutdown and undervoltage lockout.

The STEVAL-IFN004V1 is provided with a 
specific BEMF detection network with dynamic 
method selection.

Offering dedicated hardware evaluation features, 
the STEVAL-IFN004V1 board is designed to help 
developers evaluate the device and

 

develop their 

own applications. The STEVAL-IFN004V1 can be 
used together with the STM8Sxxx three-phase 
BLDC motor control software library and 
constitutes a cost-effective complete motor 
control evaluation and development platform.
