13.3.4.1 Bidirectional Current Sense Operation

The SOx pin on the DRV8353M outputs an analog voltage equal to the voltage across the SPx and SNx pins multiplied by the gain setting (GCSA). The gain setting is adjustable between four different levels (5 V/V, 10 V/V, 20 V/V, and 40 V/V). Use Equation 3 to calculate the current through the shunt resistor.
