Easy Motor Driver

Coil A+ – H-Bridge 2 Output A. Half of connection point for bi-polar stepper motor coil A.
Coil A- – H-Bridge 2 Output B. Half of connection point for bi-polar stepper motor coil A.
Coil B+ – H-Bridge 1 Output A. Half of connection point for bi-polar stepper motor coil B.
Coil B- – H-Bridge 1 Output B. Half of connection point for bi-polar stepper motor coil B.
PFD – Voltage input that selects output current decay mode. If PFD > 0.6Vcc, slow decay mode is activated. If PFD < 0.21Vcc, fast decay mode is activated. Mixed decay occurs at 0.21Vcc< PFD < 0.6Vcc.
RST – Logic Input. When set LOW, all STEP commands are ignored and all FET functionality is turned off. Must be pulled HIGH to enable STEP control.
ENABLE -Logic Input. Enables the FET functionality within the motor driver. If set to HIGH, the FETs will be disabled, and the IC will not drive the motor. If set to LOW, all FETs will be enabled, allowing motor control.
MS2 -Logic Input. See truth table below for HIGH/LOW functionality.
GND – Ground.
M+ – Power Supply. 6-30V, 2A supply.
