3 Description

The AMC23C12-Q1 is an isolated window 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

reinforced galvanic isolation of up to 5 kVRMS

according to VDE 0884-17 and UL1577, and supports

a working voltage of up to 1 kVPK.

The comparison window is centered around 0 V,

meaning that the comparator trips if the absolute

value of the input voltage exceeds the trip threshold

value. The trip threshold is adjustable from 20 mV

to 300 mV through a single external resistor and,

therefore, the comparison window ranges from

±20 mV to ±300 mV. When the voltage on the REF

pin is greater than 550 mV, the negative comparator

is disabled and only the positive comparator is

functional. The reference voltage in this mode can be

as high as 2.7 V. This mode is particularly useful for

monitoring voltage supplies.

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 AMC23C12-Q1 is available in an 8-pin, widebody

SOIC package and is specified over the full

automotive temperature range of –40°C to +125°C.
