LV8713T
Bi-CMOS LSI
PWM Constant-Current Control
Stepping Motor Driver
Overview
http://onsemi.com
The LV8713T is a stepping motor driver of the micro-step drive corresponding to supports 8W 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.
•
Control mode can be set to 2-phase, 1-2 phase, 4W1-2 phase , or 8W1-2 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.
