LB1854 - Three-Phase Brushless Motor Driver IC

Datasheet Summary

Features

  • 120° voltage linear drive technique.
  • The LB1854M soft switching scheme allows smaller external capacitors to be used (e. g. , chip capacitors).
  • Built-in thermal-shutdown function.
  • Built-in overcurrent protection circuit.
  • Built-in FG amplifiers (operational amplifier and Schmitt amplifier).
  • Control start voltage set by an external voltage.
  • The output current feedback level can be changed by changing the control gain to one of two leve.
