PRODUCTION DATA
Pull DT pin to VDD via a 20kΩ resistor to enable built-in adaptive dead time,.
To program the dead time, follow Equation 14 to select the resistor RDT. To dynamically adjust the dead time with an external analog voltage signal, follow Figure 6-29. To dynamically adjust the dead time with an external PWM signal, follow Figure 6-30.
In this application, the nominal dead time is selected to be 50ns. According to Equation 14, the programming resistor must be:
Select standard value RDT = 20kΩ.
