LV8713T
Bi-CMOS LSI
PWM Constant-Current Control Stepping Motor Driver
http://onsemi.com
Overview
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.
