LV8771VH - PWM Constant-Current Control Stepping Motor Driver

Description

The function to prevent including the turn from the input to the power supply is built into each logic pin.

Therefore, the current turns to the power supply even if power supply (VM) is turned off with the voltage impressed to the input pin and there is not crowding.

Features

  • 1 channel PWM current control stepping motor driver.
  • IO max = 1.5A.
  • Output on-resistance (High side : 0.6Ω ; Low side : 0.4Ω ; total : 1.0Ω ; Ta = 25°C, IO = 1.5A).
  • Micro step mode can be set to full-step, half-step (full torque), half-step, and quarter-step mode.
  • Built-in thermal shutdown circuit.
  • No control power supply necessary. Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Suppl.
