PULSE-WIDTH-MODULATION CONTROL CIRCUIT
SLVS052G – APRIL 1988 – REVISED JANUARY 2007
The primary function of the dead-time control is to control the minimum off time of the output of the TL594. The
dead-time control input provides control from 5% to 100% dead time. The TL594 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.
