3 Description
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.
