Cordless power tool reference design

Compact, efficient and flexible control for Brushless DC (BLDC) motor based power tools

The reference design combines Toshiba’s high efficient low-voltage MOSFET devices with Toshiba’s dedicated motor control MCU and thus provides a very compact but flexible platform for the control and drive of BLDC motors in power tools. The Motor current is generated by a 3-phase inverter with 200W output power stage using the Toshiba TPH1R204PB low-voltage MOSFET. This device features industry-leading RDS(ON) in a 5×6mm SOP Advanced package and provides low spike generation helping to prevent EMI effects. The inverter is controlled by the TMPM4K2FYADUG, an ARM®-Cortex®-M4F based MCU featuring a dedicated hardware coprocessor for sensorless Field Oriented Control (FOC)* of BLDC motors and an Advanced Programmable Motor Driver circuit (A-PMD) that allows the implementation of Low-Speed Sensorless (LSSL)* control – an advanced software algorithm providing precise control and high torque even at low rotation speed.  

Main PCB

  • Compact form factor (60 x 50 mm)
  • 3-phase inverter, 200W output stage
  • MCU with dedicated hardware supporting sensorless Field Oriented Control (FOC)* and Low-Speed Sensorless (LSSL)** control
