  • The LV8728MR is a PWM current-controlled micro step stepper motor driver. This driver can perform eight excitation modes from Full step to 1/128 step and can drive simply by the CLK input. LV8728MR is suitable for various application to have an abundant excitation mode. And overcurrent protection, thermal shutdown, and low-voltage protection circuit is built-in, it is possible to design safely as customer's application.
  • Features
  • Output on-resistance (upper side: 0.3Ω ; lower side: 0.25Ω ; total of upper and lower: 0.55Ω ; Ta = 25°C, IO = 2.0A) - Low consumption by low ON resistance
  • Full, Half, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 step excitation mode are selectable - Abundant excitation mode is selectable
  • Advance the excitation step with the only step signal input - Easy control
  • Over-current protection circuit - Safety design
  • Thermal shutdown circuit - Safety design
