THB6128 - Motor Driver

Description

of functions 9-1) Stand-by function When ST/VCC pin is at low levels, the IC enters stand-by mode, all logic is reset and output is turned OFF.

When ST/VCC pin is at high levels, the stand-by mode is released.

9-2) Step pin function CLK pin step signal input allows advancing excitation step.

Features

  • 1 channel PWM current control stepping motor driver BiCDMOS process IC Output on-resistance( High side 0.3 Ω, Low side 0.25 Ω, Total 0.55 Ω; Ta = 25°C, Io = 2.0 A) 2, 1-2, W1-2, 2W1-2, 4W1-2, 8W1-2, 16W1-2, 32W1-2 phase excitation are selectable Advance the excitation step with the only step signal input.
  • Available forward reverse control.
  • Iomax=2.2A.
  • Over current protection circuit Thermal shutdown circuit Input pull down resistanc.
