1. These pins must be connected all together to a unique PCB ground.
2. Bridges1 and 2 have 2 ground pads: one is bonded to the relative ground pin (GND1 or GND2) and the
3. The analog ground is connected to exposed pad E-Pad.
4. The pin must be tied to ground if bridge is not used as a stepper motor.

other is connected to exposed pad (E_Pad) ground ring. This makes the bond wires testing possible by
forcing a current between E-Pad and GND1 or GND2 pins and using the other pin as sense pin to measure
the resistance of E-Pad bonding. (N.B: grounds of two bridges are internally connected together).
