LV8712T Product details

Description

of operation Stepping motor control (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.PS Low or Open High Mode Standby mode Operating mode Internal regulator Standby Operating (2) The order of turning on recommended power supply The order of turning on each power supply recommends the following.

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.
