Lv8726 bipolar stepper motor driver, ultra small micro step drive capability. The device uses an external dual H bridge by P and N channel MOSFET. Operating voltage range from 9V to 55V, it is suitable for a variety of industrial applications. Implementation of all H bridges in the MOSFET switching process to reduce power consumption is synchronous rectifier control. The device uses PWM to achieve constant current control. Step sequencer, ranging from half step to the 1 / 128 micro step is driven by a clock input. The configuration register can be programmed through a SPI serial interface to further improve the energy efficiency of the device which can enter the energy-saving standby mode
