LV8727
Overview
The LV8727 is a micro-step stepper motor driver for bipolar stepper motors controlled by PWM.
This LV8727 supports eight micro step resolutions of Half, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10 and 1/20, which
is driven simply by step input.
Function
• Single-channel PWM current control stepper motor driver.
• BiCDMOS process IC.
• Output on-resistance (upper side: 0.25; lower side: 0.15; total of upper and lower: 0.4; Ta = 25˚C, I
O
=
4.0A)
• Half, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20 Step are selectable.
• Advance the excitation step with the only step signal input.
• Available forward reverse control
• Over current protection circuit
• Thermal shutdown circuit
• Input pull down resistance.
• With reset pin and enable pin.
Typical Applications
• Large format Printer
• Stage Lighting
Bi-CMOS LSI
