SL-PTOOL2V1
- Reference Design

Compact reference design for battery-operated brushless power tools 36V-72V
This three-phase brushless motor driver represents a ready-to-use solution for heavy-duty cordless power tool applications supplied by higher voltage 8S to 15S battery packs. It frees developers from complex design considerations involving size constraints, heat management, operational and standby efficiency, as well as the control and feedback mechanisms necessary for high performance operation with guaranteed reliability. The design is based on the highly integrated STSPIN32F0252 System-In-Package capable of driving three with dedicated firmware ready to run field-oriented control, 6-step sensorless and other advanced driving algorithms, a triple half-bridge gate driver, and a comparator featuring advanced SmartShutDown functionality for rapid overload and overcurrent protection. High-voltage bootstrap diodes are also integrated, as well as anti-cross conduction, deadtime and UVLO protection on both the lower and upper driving sections to prevent the power switches from operating in low efficiency or failure causing conditions. The power stage STL130N8F7 N-channel power MOSFET ensures very low switching losses, coupled with high current capability and low thermal resistance for highly efficient and reliable motor driving operation in a compact surface mount PowerFLAT 5x6 package.
