LV8741V: PWM Current Control Stepper Motor Driver

Description: The LV8741V is a 2-channel H-bridge driver IC that...
  • The LV8741V 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 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
  • On resistance (upper side : 0.5Ω ; lower side : 0.5Ω ; total of upper and lower : 1.0Ω ; Ta = 25°C, IO = 1.5A) - High Efficiency
  • Excitation mode can be set to Full-step, Half-step full torque, Half-step or Quarter-step - Various Step Adjustment Available
  • Motor current selectable in four steps - Low Consumption
  • Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated - Safety Design
  • Thermal shutdown circuit and power supply monitor circuit incorporated - Thermal protection, Low voltage detection
  • CLK-IN Input - Easy Control for Micro-step Drive
  • 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
  • IO max = 1.5A
  • No control supply required VCC = 3.3V
  • Unusual Condition Warning Output Pin
