Technical and Functional Specifications

  • Supports 12V power supply system with up to 250 W automotive BLDC/PMSM motor control system
  • Supporst BLDC/PMSM sensorless FOC control, both dual shunt and single shunt
  • Robust and fast start-up, meeting the strict start-up condition ❮ 150ms from standstill to the rated speed;
  • Crossing the current I/F start-up and initial position detection algorithm make sure the start-up successful
  • Board tested against the supply voltage changing, load changing, speed command jumping, and temperature rising
  • Supports multiple diagnoses and protection strategies using the robust gate driver unit (GDU); also supports over-voltage (OV), under-voltage (UV), short- and over-current (OC), over-temperature (OT), and stall detection.
  • Supports speed commands from PWM/FreeMASTER/LIN by user define
