概览

LB11922 是一款用于三相无电刷电机恒定速度控制的预驱动器集成电路。它通过对于输出级使用分立晶体管，实施带有所需输出能力（电压和电流）的电机驱动器。它实施直接 PWM 驱动，最大程度减小可功率损耗。

  • Direct PWM drive output
  • Speed discriminator + PLL speed control circuit
  • Speed lock detection output
  • Built-in crystal oscillator circuit
  • Forward/reverse switching circuit
  • Braking circuit (short braking)
  • Full complement of on-chip protection circuits, including lock protection, current limiter, and thermal shutdown protection circuits.
