X-NUCLEO-IHM08M1 Low-Voltage BLDC motor driver expansion board based on STL220N6F7 for STM32 Nucleo Data brief Description The X-NUCLEO-IHM08M1 is a three-phase brushless DC motor driver expansion board based on the STL220N6F7 STripFET F7 Power MOSFET for STM32 Nucleo. It provides an affordable and easy-to-use solution for driving three-phase brushless DC motors as part of our STM32 Nucleo project. The XNUCLEOIHM08M1 is compatible with the ST morpho connector and supports the addition of other boards which can be connected with a single STM32 Nucleo board. The user can also mount the Arduino UNO R3 connector. The IC driver used on this expansion board is the L6398 Features single-chip half bridge gate driver for the N- channel power MOSFET. The L6398 gate driver 3-phase driver board for BLDC/PMSM plus STL220N6F7 Power MOSFET combination motors forms the high current power platform for the Nominal operating voltage range from 10 V BLDC motor and the digital section based on the to 48 V DC STM32 Nucleo board offers 6-step or FOC 15 A output current algorithm control solutions, which you can select RMS in the firmware. Operating frequency selectable by firmware Overcurrent detection and protection (30 Apeak) Thermal monitoring and overheating protection Compatible with STM32 Nucleo boards Equipped with ST morpho connectors 3-Shunt and 1-Shunt configurable jumpers for motor current sensing Hall/Encoder motor sensor connector and circuit Debug connector for DAC, GPIOs, etc. Potentiometer available for speed regulation User LED RoHS compliant June 2017 DocID028748 Rev 3 1/6 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram X-NUCLEO-IHM08M1 Schematic diagram Figure 1: Schematic - Power section (1/2) Figure 2: Schematic - Power section (2/2) 2/6 DocID028748 Rev 3
