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.
