STMicroelectronics Reference Design Based on STSPIN32F0B for Power Tool Driven by LV BLDC Motors Motor Controller for

The STMicroelectronics STEVAL-PTOOL1V1 compact 70 mm x 30 mm reference design board is tailored for low voltage power tools driven by 3-phase brushless motors, supplied by 2S to 6S batteries. The design is based on the STSPIN32F0B controller and STL180N6F7 (or STL220N6F7) Power MOSFET. The board is ready for sensorless and sensored FOC, and can be configured for six-step sensorless control through available BEMF sensing circuitry.

• Recommended for power tools supplied from 2S to 6S batteries
• Output current up to 15 Arms
• STSPIN32F0B advanced 3-phase motor controller tailored for single-shunt applications
• STL180N6F7 60 V, 1.9 mΩ N-channel power MOSFET
• Ultra-low standby current below 1μA thanks to an external turn-on/off trigger
• Heat sink for improved power dissipation
• Extremely compact footprint (70 mm x 30 mm)
• Input connector for Hall effect sensors and encoder
• Plug-and-play capability through six-step firmware with Hall effect sensor feedback
