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.
