  • The combination of TPD4207F and TMPM4K0FSADUG achieves high efficiency compressor motor (BLDC) drive by vector control
  • Able to drive a compressor motor which requires high current at startup because of improved current rating (5A) due to low on resitance (0.44Ω(typ)) MOSFETs installed
  • Built-in a voltage regulator, a current limit and an undervoltage protection circuit help to simplify board design


  • Description of control method of BLDC motor drive(sensorless drive and sine-wave control)
  • Application circuit example of compressor motor drive with the combination of TPD4207F and TMPM4K0FSADUG
  • Design guide of peripheral circuit such as protection circuit threshold setting
