1 / 5 page October 2011 Doc ID 022372 Rev 1 1/5 5 STEVAL-IFN004V1 BLDC six-step motor driver based on the L6230 and STM8S105 Features ■ Input range: 8 V up to 48 V (up to 35 W) ■ STMicroelectronics’ STM8S105 8-bit microcontroller ■ DMOS fully integrated three-phase motor driver L6230 in a QFN package ■ Four-layer board ■ Best miniaturization vs. thermal performance ratio ■ Sensorless and hall-effect sensor operation ■ Current sensing mode: single-shunt resistor ■ Debug connector ■ SPI interface ■ RoHS compliant 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. www.st.com |
