NCP4355
Normal operation waveforms for typical load detection
connection and improved load detection waveforms are
shown in Figure 29. Figure 30 shows waveforms for
NCP4355A (without VMIN detection) in OFF mode and
when load is connected during OFF mode. It can be seen that
the application is waiting not for low VOUT, but for low VCC
and then OFF mode is ended.
