Description
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.
