Product Line

RT7100

The RT7100 is a 3 phase motor controller for BLDC motor control applications. It integrates ARM32-bit Cortex-M0 core and peripheral circuits to perform Field-Orientated-Control (FOC) and Sensorless motor control. The RT7100 has integrated various system level peripheral functions, such as ADC, DAC, communication interface, SVPWM, watchdog timer, current sensing, over-current protection and motor lock protection so as to reduce component count, board space and system cost. By utilizing these features, the RT7100 provides a unique selection in a wide-range of motor drive applications.

To meet IEC 60730-1 Class B safety standard for household applications, the RT7100 has a version that has been certificated by UL for the compliance (UL Certified No. E478780). Below shows the benefits for the UL certificated version.

  • Assure operation safety under fault conditions
  • Shorten safety certification process, i.e., Time to market
  • Applications and process cost saving for customer

Our products come with tuning tool, control library and FW examples as well as technical documentations to lower design complexity, shorten motor tuning process and reduce development cycle. For more details, please contact us.
