In the DRV8328, high- and low-side inputs operate independently, with an exception to prevent cross conduction when the high and low side of the same half-bridge are turned ON at same time. The device turns OFF high- and low- side output to prevent shoot through when high- and low-side inputs are logic high at same time.

The DRV8328 also provides dead time insertion to prevent both external MOSFETs of each half-bridge from switching on at the same time. In devices with a DT pin, deadtime can be linearly adjusted between 100 ns and 2000 ns by connecting s resistor between DT and ground. When the DT pin is left floating or connected to GND, a fixed deadtime of 55 ns (typical value) is inserted. The value of the resistor can be calculated using following equation.
