EK74 Rev A
Figure 5 and 6 show the input, output and over current flag waveforms when a PA 165 is evaluated using
the EK74 evaluation kit. The yellow waveform (channel 1) represents an input signal of 4V
P‐P
and cyan wave‐
form (channel 2) represents an output signal of 100V
P‐P.
Magenta waveform (channel 3) represents the over
current flag.
During normal operation, the over current flag will remain high as shown in figure 5. When the amplifier
starts operating in current limit mode, the over current flag becomes low as shown in figure 6.
