LV8731 Stepper Motor Driver PWM Constant Current Control 2 Phase 2A 16 Microstep 100KHZ

LV8731 Stepper Motor Driver PWM Constant Current Control 2 Phase 2A 16 Segment Microstep

Description:
- The LV8731 is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports 4W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
       
Features:
- Low on resistance (upper side : 0.3Ω; lower side : 0.25Ω; total of upper and lower : 0.55Ω; Ta = 25°C, IO = 2A)
- High Efficiency
- Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase
