LV8772 - PWM Constant-Current Control Stepping Motor Driver

Description

This IC is switched between standby and operating mode by setting the ST pin.

power-save mode and all logic is reset.

Features

  • Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2.5A).
  • Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase.
  • BiCDMOS process IC.
  • Excitation step proceeds only by step signal input.
  • Motor current selectable in four steps.
  • Output short-circuit protection circuit incorporated.
  • Unusual condition warning output pins.
  • No control power s.
