Overview
Description
This solution is showing a motor control reference design for power tools. The power source (battery or main power supply) is not part of this proposal and is represented here as a simple battery pack.
For this reference design, Renesas choose a high voltage solution (48V), which features the high-performance Arm® Cortex®-M4 based RA6M3 MCU. It has specific PWM timers for 3-phase motor control and a floating point unit (FPU) to enhance algorithm performance.
This block diagram shows a setup that includes an embedded power supply for the MCU (3.3V) and MOSFET half-bridge drivers (12V).
System Benefits:
- High integration MCU with touch/LCD/ADC/DAC features
- Volatile organic compounds (VOC)/temperature sensor
- Light sensor to support filter exchange detection
