8.3.1.2 Hardware Interface Mode

The DRV8306 device supports a hardware interface mode for simple end-application design. In this hardware interface device, the VDS overcurrent limit and the gate drive current levels can be configured through the resistor-configurable inputs, IDRIVE and VDS. This feature lets the application designer configure the most commonly used device settings by tying the pin logic high or logic low, or with a simple pullup or pulldown resistor.

The IDRIVE pin configures the gate drive current strength. The VDS pin configures the voltage threshold of the VDS overcurrent monitors.

For more information on the hardware interface, see the Pin Diagrams section.
