6 Use case No. 2: DC+ overcurrent detection

As shown in location 2 of Figure 6-1, the AMC23C11 can be a good choice for DC+ overcurrent detection.

Figure 6-2 shows an overcurrent event output waveform. Like the AMC23C12, the AMC23C11 has an open-drain output, OUT, that actively pulls low when the input voltage exceeds the pre-defined threshold value of the voltage on the reference pin. The AMC23C11 also supports latched mode with a LATCH input pin that clears the output only after the latch clears. If you require both overcurrent and short-circuit detection, you can use the AMC23C14 to set the two threshold levels for overcurrent and short-circuit detection, respectively.
