LV8712T - PWM Constant-Current Control Stepping Motor Driver

Description

(1) Power save function This IC is switched between standby and operating mode by setting the PS pin.

In standby mode, the IC is set to power-save mode and all logic is reset.

In addition, the internal regulator circuit do not operate in standby mode.

Features

  • Single-channel PWM constant-current control stepping motor driver incorporated.
  • Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 2W1-2 phase.
  • Microstep can control easily by the CLK-IN input.
  • Power-supply voltage of motor : VM max = 18V.
  • Output current : IO max = 0.8A.
  • Output ON resistance : RON = 1.1Ω (upper and lower total, typical, Ta = 25°C ).
  • A thermal shutdown circuit and a low voltage detecting ci.
