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.
Synchronous rectification control is implemented for all H-bridges to lower power dissipation during a MOSFET switching.
The device implements constant-current control using PWM at 125 kHz (typ.
) switching frequency that enables the least noise motor drive solution.
A built-in linear regulator powers internal logic circuit directly from the motor supply voltage, VM, thus eliminating need for any external regulator.
A proprietary internal current sensing mechanism is implemented that eliminates up to four external current sense power resistors and improves the system energy efficiency signific...
