Overview

This controller synthesizes the optimal driving signal from hall sensor signals, and outputs the synthesized signal to control the external level shifter and power transistor. The replacement is also easy because of its pin compatibility with BD62011AFS and BD62014AFS.

  • 150° commutation logic
  • PWM control (Upper arm switching)
  • Phase control supported from 0° to +30° at 1° intervals
  • Rotational direction switch
  • FG signal output with pulse number switch (4 or 12)
  • VREG output (5V/30mA)
  • Protection circuits provided: OCP, TSD, UVLO, MLP and the external fault input (FIB)
