7.4 Device Functional Modes

The DRV7167A operates in normal mode and UVLO mode. See Section 7.3.2 for information on UVLO operation mode. In the normal mode, the output state is dependent on the states of the HI and LI pins.

Table 7-3 lists the output states for different input pin combinations for DRV7167A. This device supports overlap protection/interlock functionality. If both HI and LI are asserted, both GaN FETs in the power stage are turned off.
