Features• 7 - 45 V motor voltage rating supported• 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• Six-steps sensorless control available through dedicated BEMF sensing circuitry
and sensorless/sensored Field Oriented Control• Speed regulation through an external trimmer• Protections: thermal shutdown, UVLO, overcurrent and reverse biasing of power
stage outputs• SWD debug interface and direct firmware update (DFU) via UART
DescriptionThis STEVAL-PTOOL1V1 compact 70 mm x 30 mm reference design board istailored for low voltage power tools driven by 3-phase brushless motors, suppliedby 2S to 6S batteries. The design is based on the STSPIN32F0B controller andSTL180N6F7 (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. The accompanyingsix-step STSW-PTOOL1V1 firmware uses position feedback from Hall effect sensors,with debugging and programming capability available through the SWD interface andthe direct firmware update feature.
The board can deliver up to 15 A continuous current, thanks also to the optimalthermal dissipation provided by an embedded heatsink. It embeds a fast power-oncircuit that connects and disconnects the battery, allowing standby consumptionbelow 1 μA for extended battery duration. Several protection features are included,such as thermal shutdown, undervoltage lockout, overcurrent protection withprogrammable threshold and reverse biasing of power stage outputs.
This reference design is predominately intended for power tools, but is verysuitable for any battery-powered application involving similar architecture, rating andperformance. A potentiometer input for speed variation is available.
