概览

LV8850GA 是一款预驱动器集成电路，是三相、无传感器，带 PWM 的驱动器。LV8850GA 驱动时无需霍耳传感器，适用于驱动需要高可靠性和长寿命的高电流电机。

  • VCC+7V charge pump booster circuit for output drive
  • Integrated Synchronous Rectifier circuit (Selected by SYNSEL pin)
  • PWM or DC input signal is selectable (Selected by CTLSW pin)
  • Adjustable PWM frequency (By the external capacitor at DC input mode)
  • Integrated Current Limit circuit (highly accurate detection by using sensing (RFGND) pin for monitoring)
  • Integrated Forward / Reverse rotation switch circuit (Selected by F/R pin)
  • Integrated Lock Protection circuit with auto-recovery
  • Output Lock Protection signal (RD pin) / Output 1-hole FG signal (FG pin)
