产品

概览

LB11822 是一款三相无电刷电机驱动器，用于驱动激光打印机和普通复印机中带有硒鼓和进纸电机。此器件采用直接 PWM 驱动技术，可实现绩效功率损耗。通过实施 LB11822 和 LB11825M，可实现响应外部提供时钟频率（对应于 FG 频率）的电机速度灵活控制。

  • Three-phase bipolar drive (30 V, 3.1 A)
  • Direct PWM drive
  • Built-in low side inductive kickback absorbing diode
  • Speed discriminator + PLL speed control
  • Speed locked state detection output
  • Built-in forward/reverse switching circuit
  • Full complement of built-in protection circuits, including current limiter circuit, thermal protection circuit, and motor lock protection circuit.
