GND13PWRDevice groundBoth the GND pin and device PowerPAD intergrated circuit package must be connected to ground
PPAD
nFAULT8ODFault indication pinPulled logic low with fault condition; open-drain output requires external pullup
nSLEEP1ISleep mode inputLogic high to enable device; logic low to enter low-power sleep mode; internal pulldown
VINT14—Internal regulatorInternal supply voltage; bypass to GND with 2.2μF, 6.3V capacitor
VM12PWRPower supplyConnect to motor power supply; bypass to GND with a 0.1 and 10μF (minimum) ceramic capacitor rated for VM
VREF11IFull-scale current reference inputVoltage on this pin sets the full scale chopping current; short to VINT if not supplying an external reference voltage
