The LV8728MR is a PWM current-controlled micro step stepper motorwww.onsemi.comdriver. This driver can perform eight types of excitation mode from Full stepto 1/128 step 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: 0.3W ; lower side: 0.25W ; total of upper
and lower: 0.55W ; Ta = 25°C, IO = 2.0A)
· Full, Half, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 step excitation mode are selectable
· Advance the excitation step with the only step signal input
· Available forward reverse control
· IO max = 2.0A
· Over-current protection circuit
· Thermal shutdown circuit
· Input pull down resistance
· With reset pin and enable pin.
Typical Applications
· Printer (Multi-function printer, 3D printer, etc.)
· Security camera
· Scanner
· Stage light
