To use the built-in adaptive dead time, the DT pin must be connected to VCCA pin.
To program the dead time, follow Equation 15 to select the resistor RDT. To dynamically adjust the dead time with an external analog voltage signal, follow Equation 19. To dynamically adjust the dead time with an external PWM signal, follow Equation 20.
In the example circuit, the nominal dead time is selected to be 55 ns. According to Equation 15, the programming resistor should be:
Select the standard value, RDT = 10 kΩ.
