LB1876: Three-Phase Brushless Motor Driver for Polygon Mirror Motors

The LB1876 is a driver for polygon mirror motors such as used in laser printers and similar equipment. It incorporates all necessary circuitry (speed control + driver) on a single chip. Direct PWM drive enables drive with low power loss.

特性
  • 3-phase bipolar drive
  • Direct PWM drive technique
  • Built-in lower side output diode
  • Output current limiter
  • Reference clock input circuit (FG frequency equivalent)
  • PLL speed control circuit
  • Phase lock detector output (with masking function)
  • Built-in protection circuitry includes current limiter, restraint protection, overheat protection, low-voltage protection, etc.
  • Brake method switching circuit (free-run or reverse torque)
  • 5V regulator output
  • Power save function
