Description

Motor driver for cordless power tools using  low loss element TPH1R204PB within small package. The motor speed is controlled by MCU. Description of circuit design method. 

Features

  • 2 types of drive methods, square wave drive and sine wave drive, are switchable
  • It can control the revolving speed of motor optimally by MCU 
  • TPH1R204PB, that is low power loss and low spike voltage, is used for output elements.
  • 3 shunt type current detector is mounted for PCB, and it can also support sensor-less control. 
  • Protecting function from over current and etc. is mounted. 
  • Standby power reduction circuit operate after a certain period that the motor is not rotating. 
  • It consists of 2 PCBs of a main board and interface board, and contributes to the miniaturization of a power tool.
