LV8714TA Overview
LV8714TA Dual Stepper Motor Driver with Ultra-small Micro Steps The LV8714 is a fully integrated dual bipolar/unipolar stepper motor driver with ultra-small micro step drive capability. Alternatively, it can be used to drive four DC motors independently. The device includes low RDS(ON) (upper + lower = 0.9Ω) type MOSFETs based quad H-bridges with gate drivers and can drive up to 1.5A per H-bridge.
