LV8774Q: PWM Constant-Current Control Stepper Motor Driver

具体说明: The LV8774Q is a 2-channel H-bridge driver IC, and...
  • The LV8774Q is a 2-channel H-bridge driver IC, and can drive a stepper motor or two brushed DC motors. A stepper motor driver supports micro-step drive with 1/16-step resolution, and two brushed motor drivers support forward, reverse, brake, and standby functions. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
  • 特性
  • Low on resistance
    (upper side : 0.3Ω, lower side : 0.25Ω, total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A) - High Efficiency
  • Micro-step mode can be set to Full-step, Half-step, Quarter-step, or 1/16-step - Various Step Adjustment Available
  • Excitation step proceeds only by step signal input withstepper motor - Easy Control for Micro-step Drive
  • Motor current selectable in four steps - Low Consumption
  • Output short-circuit protection circuit
    (selectable from latch-type or auto-reset-type) - Safty Design
  • Unusual condition warning output pins - Safty Design
  • Single-channel PWM current control stepper motor driver
    (or two DC motor driver)
