PWM Constant-Current Control  
Stepper Motor Driver  
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, I = 1.8A)  
O
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.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.  
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,  
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.  
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed,  
damage may occur and reliability may be affected.
