LV8726TA Stepper Motor Pre-Driver, PWM, Constant-Current Control, Micro step Overview The LV8726 is a bipolar stepper motor driver with ultra-small micro step drive capability.

The device uses external dual H-bridges consisting of P and N channel MOSFETs.

The operation voltage range is from 9V to 55V, and it is applicable to various industrial applications.

Synchronous rectification control is implemented for all H-bridges to minimize power dissipation during a MOSFET switching.

The device impl
