2.5A BIPOLAR STEPPER MOTOR DRIVER LV8772E




Tiny Board has been designed around LV8772 IC from On-Semi. This driver is capable of micro-step drive and supports 4W 1-2 phase excitation. It has Low on Resistance with motor current selectable in four steps. The board is equipped with unusual condition warning LED and input Pulse Monitor LED. It is most suitable for the drive of a stepping motor for OA, amusements, hobby CNC, 3D printers, automatic machines, linear guides, motion control systems, XY gantry, Camera focus and zoom controller, Mini camera Pan Tilt Head.

Chip Enable Functions (Default this pin set to high for normal operation)

  • ST Pin High Operation Mode, Low Disable the drive
  • This IC is switched between standby and operating mode by setting the ST pin, In standby mode, the IC is set to power-save mode and all logic is reset. In addition, the internal regulator circuit and charge pump circuit do not operate in standby mode.

Position detection monitoring function (LED MO, D2)

  • When the excitation position is in the initial position, the Monitor output LED MO D2 placed in the ON State

Setting constant-current control reference current (PR1 Potentiometer)

  • Potentiometer PR1 is to set the Current
