APPLICATION INFORMATION
How to Set Dead Time
The primary function of the dead-time control is to control the minimum off time of the output of the TL594
device. The dead-time control input provides control from 5% to 100% dead time. The TL594 device can be
tailored to the specific power transistor switches that are used, to ensure that the output transistors never
experience a common on-time. The bias circuit for the basic function is shown in Figure 7.
