» Product Change Notification
The LV8734V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports 2W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
Features   Benefits
     
  • Low ON resistance (upper side: 0.48Ω ; lower side: 0.32Ω ; total of upper and lower: 0.8Ω , Ta = 25°C, IO=1.5A)
 
  • High Efficiency
  • Output short-circuit protection circuit (selectable from latch type or auto-reset type) incorporated
 
  • Short protection
  • Excitation : Full, Half, Quarter, 1/8 Step
 
  • Various Step Adjustment Available
  • Motor current Selectable in 4 Steps
 
  • Low Consumption
  • OCP : Latch/Auto reset
 
  • Safety Design
  • CLK-IN Input
 
  • Easy Control for Micro-step Drive
  • This device is a single channel PWM current control stepping motor driver (selectable with DC motor driver channel 2)
   
  • Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase, or 4W1-2 phase
   
  • Unusual condition warning output pins
   
  • No control power supply required
