8.3.1.2 Mode (Inverting and non inverting INLx)

The DRV8300 has flexibility of accepting different kind of inputs on INLx. In devices with MODE pin (QFN

package device), the DRV8300 provides option of GLx output inverted or non-inverted compared to polarity of

signal on INLx pin. When MODE pin is left floating INLx is configured to be in non-inverting mode and GLx

output is in phase with INLx (see Figure 8-4), whereas when MODE pin is connected to GVDD, GLx output is out

of phase with inputs (see Figure 8-5). In devices without MODE pin (TSSOP package device), there are different

device option available for inverting and non inverting inputs (see Section 5)
