The AMC23C15-Q1 is a dual-channel, isolated window comparator with a short response time. Its open-drain output is separated from the input circuit by an isolation barrier with strong anti-magnetic interference ability. This barrier complies with VDE 0884-17 and UL1577 standards, providing reinforced electrical isolation of up to 5 kVRMS and supporting an operating voltage of up to 1 kV_PK. The windows of both comparators are centered at 0 V, meaning that the comparators will trigger when the input exceeds the thresholds in both positive and negative directions. One of the comparators has a fixed threshold of ±60 mV. The threshold of the second comparator can be adjusted from ±5 mV to ±300 mV through a single external resistor. The AMC23C15-Q1 also supports the positive-only comparator mode. When the voltage on the REF pin is greater than 550 mV, the negative comparator is disabled, and only the positive comparator operates. In this mode, the reference voltage can be up to 2.7 V. This mode is particularly suitable for monitoring positive power supply voltages.
