Description

BD6425EFV, BD6423EFV, BD6422EFV are a low power consumption PWM constant current-drive driver series of stepping motor with power supply's rated voltage of 45V and rated output current of 1.0A, 1.5A. For input interface, BD6425 / 6423EFV is CLK-IN drive mode and BD6422EFV is parallel IN drive mode. There are excitation modes of FULL STEP & HALF STEP (2 kinds), QUATER STEP mode, and for current decay mode, four kinds of ratio of FAST DECAY & SLOW DECAY can be set, so the optimum control conditions for every motor can be realized. In addition, being able to drive with one system of power supply makes contribution to the set design's getting easy.

Features

・Low on-resistance DMOS, rated output current 1.5A・CLK-IN drive・QUARTER STEP・Power-saving function・Forward rotation & reverse rotation switching function・TSD(Thermal Shutdown) circuit・OCP(Over Current Protection) circuit・UVLO(Under Voltage Locked Out) circuit・Power ON reset function・Compact, thin-shape, and high heat dissipation package・Current decay mode selection(Mix decay)・One power supply system 45V

Typical applications

  • serial dot impact printer
  • sewing machine
