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
