7.2.4 Application Curves

Figure 7-3 shows the typical response of the AMC23C10 to a 400mVPP sinusoidal input waveform applied to the INP pin, while INN in grounded (0V). Both outputs switch when the input crosses the 0V plus comparator hysteresis level.

The integrated LDO of the AMC23C10 greatly relaxes the power-supply requirements on the high-voltage side and allows powering the device from non-regulated transformer, charge pump, and bootstrap supplies. As given by the following image, the internal LDO provides a stable operating voltage to the internal circuitry, allowing the trip thresholds to remain mostly undisturbed even at ripple voltages of 2VPP and higher.
