产品概述
描述
The STEVAL-PTOOL2V1 BLDC driver reference design is tailored for battery-operated power tools using 8S to 15S battery packs. It is based on the STSPIN32F0252 motor controller with embedded 3-phase, 250 V gate driver and low-power STM32 MCU. The power stage is based on the STL130N8F7 power MOSFETs or any similarly rated device in a PowerFlat 5x6 package.
The board implements single shunt sensing topology with both field-oriented control
(FOC) and sensored or sensorless 6-step control supported for driving permanent magnet synchronous motors (PMSM) and brushless DC (BLDC) motors.
The companion 6-step STSW-PTOOL2V1 firmware is ready to use with position feedback from phase Hall-effect sensors.
This reference design can deliver up to 19 A continuous current with very good thermal dissipation performance thanks to the mounted heatsink. It is compatible with a wide input voltage range from 20 to 72 VDC, and includes an auxiliary power stage with the VIPER013 in buck configuration to generate +12V and +3.3V supply voltage required by the application.
The STEVAL-PTOOL2V1 features a potentiometer for speed variation and protection features include thermal shutdown, undervoltage lockout, and overcurrent protection.
This compact 80 mm x 58 mm design is ideal for power tools and any similar battery-operated applications in terms of architecture, rating and performance.
