Motor Driver
Overview
The LV8741V is a PWM current-control stepping motor driver IC.
Features
• Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated.
• BiCDMOS process IC
• On resistance (upper side : 0.5Ω ; lower side : 0.5Ω ; total of upper and lower : 1.0Ω ; Ta = 25°C, IO = 1.5A)
• Excitation mode can be set to 2-phase, 1-2 phase full torque, 1-2 phase or W1-2 phase
• Excitation step proceeds only by step signal input
• Motor holding current selectable in four steps
• IO max = 1.5A
• Output-stage push-pull structure enabling high-speed operation
• Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
• Thermal shutdown circuit and power supply monitor circuit incorporated
• Supports control power supply VCC = 3.3V
