The AMC22C11-Q1 is an isolated comparator with a short response time. The open-drain output is separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide galvanic isolation of up to 3 kVRMS according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, and supports a working voltage of up to 560 VRMS.

The trip threshold is adjustable from 20 mV to 450 mV in low-hysteresis mode and from 600 mV to 2.7 V in high-hysteresis mode through a single external resistor.

The open-drain output on the device supports transparent mode (LATCH input tied to GND2) where the output follows the input state, or latch mode, where the output is cleared on the falling edge of the latch input signal.

The AMC22C11-Q1 is available in an 8-pin SOIC package and is specified over the full automotive temperature range of –40°C to +125°C.
