DRV8320: 1X MODE

Hey Nimesh,

The 1x PWM mode as the name suggests takes the PWM signals on the INHA pin and the rest of the pins are used as logic pins to determine, the half bridge outputs, direction and brake. Please check out section 8.3.1.1.3 for more info and Table 4,5  on the logic states and their corresponding output to determine how you would like to implement the 1x mode. Figure 18 and 19 are also useful to get an idea on how the connections are made.

Typically the hall signals are connected directly otherwise you will need to have the external microcontroller provide the logic states.

Best,
Akshay
