产品信息

The LV8729V is a PWM current-controlled micro step bipolar stepper motor driver. This driver can do eight ways of micro step resolution of 1/128 step from Full step, and can drive simply by the CLK input.
  • Output on-resistance (upper side : 0.35Ω ; lower side : 0.3Ω ; total of upper and lower : 0.65 ; Ta = 25°C, IO = 1.8A)
  • 2-phase, 1-2 phase, W1-2 phase, 2W1-2 phase, 4W1-2 phase, 8W1-2 phase, 16W1-2 phase, 32W1-2 phase excitation are selectable.
  • Over current protection circuit.
  • Thermal shutdown circuit.
  • Single-channel PWM current control stepper motor driver.
  • BiCDMOS process IC.
  • Advance the excitation step with the only step signal input.
  • Available forward reverse control.
  • Input pull down resistance
  • With reset pin and enable pin
