LV8712T

Overview

The LV8712T is a stepping motor driver of the micro-step drive corresponding to supports 2W 1-2 phase excitation. It is

the best for the drive of the stepping motor for a scanner and a small printer.

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 circuit are built into.
