¡El 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. ¡El 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. ¡El 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 significantly. External VREF input signal for each H-bridge controls the drive step size and can achieve over 256 micro step resolution. Individual controls signals (ENAx and INx) are provided for controlling each H-bridge channel independently with forward and reverse direction control. To enhance energy efficiency further, the device can be put into a power saving standby mode, when idle.
