Automotive high-speed reinforced isolation differential comparator, open-drain and push-pull output

The AMC23C10-Q1 is a precision, isolated comparator with a short response time.

This device is specifically designed for zero-crossing detection of high-voltage

signals that are galvanically isolated from low-voltage circuitry. The open-drain

and push-pull outputs are 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 up to 5kVRMS according to VDE

0884-17 and UL1577. This barrier also supports a working voltage up to

1kVRMS.

The device offers an open-drain and a

push-pull output with a propagation delay of less than 320ns. The integrated

low-dropout (LDO) regulator supports an operating voltage range of 3V to 27V on the

high-voltage side. Thus, allowing the comparator to be powered from a wide range of

power supplies. The operating voltage range on the low-side is 2.7V to 5.5V.

The AMC23C10-Q1 is available in an 8-pin, wide-body SOIC package and is specified

over the extended industrial temperature range of –40°C to +125°C.
