Connect to motor supply voltage; bypass to GND
with a 0.1 µF plus a 100 µF capacitor rated for VBB
Must be connected to ground
Connect a 16 V, 0.1 µF ceramic capacitor to VBB
Connect a 0.1 µF X7R capacitor rated for VBB
between CP1 and CP2

Logic high enables the high side ½-H bridge FET;
logic low enables the low side FET; internal
pulldown
Logic high enables ½-H bridge output; logic low
puts the FETs in HI-Z; internal pulldown
Pull logic low to put device into a low-power sleep
mode; internal pulldown
Pulled logic low with fault condition; open-drain
output requires an external pullup
