Overview
Ordering number : ENA1702D LV8729V Bi-CMOS IC PWM Constant-Current Control Stepper Motor Driver http://onsemi.
com Overview The LV8729V is a PWM current-controlled microstep bipolar stepper motor driver.
This driver can perform eight times of excitation of the second phase to 32W1-second phase and can drive simply by the CLK input.
Function • Single-channel PWM current control stepper motor driver.
• BiCDMOS process IC.
• Output on-resistance (upper side : 0.
35Ω ; lower side : 0.
3Ω ; total of upper and lower : 0.
65Ω ; Ta = 25°C, IO = 1.
8A) • 2-phase, 1-2 phase, W1-2 phase, 2W1-2 phase, 4W1-2 phase,8W1-2 phase, 16W1-2 phase, 32W1-2 phase excitation 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.
