STEVAL-IFN004V1:BLDC six-step motor driver based on the

L6230 and STM8S105

The STEVAL-IFN004V1 demonstration board is based on the DMOS fully integrated three-

phase motor driver L6230 and STMicroelectronics' STM8S105 microcontroller 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.

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.

For more details on the STEVAL-IFN004V1 refer to the user manual UM1477.
