7.1 Overview

The AMC23C10 is an isolated comparator with an open-drain and push-pull output that is specifically designed for zero-crossing detection of high-voltage signals that must be galvanically isolated from low-voltage circuitry. The comparator compares the input voltage (VINP) against the reference voltage (VINN) that is typically 0 V (INN is shorted to GND1). The open-drain output is actively pulled low when VINP is above VINN and returns to a high-impedance (Hi-Z) state when VINP is below the VINN level. The push-pull output is actively driven high when VINP is above VINN and is actively driven low when VINP is below the VINN level. The comparator has built-in hysteresis (VHYS) that is centered around VINN.

Galvanic isolation between the high- and low-voltage side of the device is achieved by transmitting the comparator states across a SiO2-based, reinforced capacitive isolation barrier. This isolation barrier supports a high level of magnetic field immunity, as described in the ISO72x Digital Isolator Magnetic-Field Immunity application report. The digital modulation scheme used in the AMC23C10 to transmit data across the isolation barrier, and the isolation barrier characteristics itself, result in high reliability and common-mode transient immunity.
