  • The LV8740V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports Quarter-step excitation, and two channels of a brushed DC 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.
  • 特性
  • On resistance (upper side : 0.3Ω ; lower side : 0.2Ω ; total of upper and lower : 0.5Ω ; Ta = 25°C, IO = 2.5A) - Good Thermal Performance, High efficiency
  • Excitation mode can be set to Full-step, Half-step full torque, Half-step , or Quarter-step - Various Step Adjustment Available
  • Motor holding current selectable in four steps - Low Consumption
  • Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated - Safety design
  • Built-in thermal shutdown circuit - Thermal protection
  • No control power supply required - Easy Design
  • Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated.
  • BiCDMOS process IC
  • Excitation step proceeds only by step signal input
  • Unusual condition warning output pins
  • Forward/Reverse/Brake/Stand-by Function
