BLDC six-step motor driver based on the L6230 and STM8S105
  • active Active

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.
