The AMC23C10 is a precision, isolated comparator with a short response time that is specifically designed for zero-crossing detection of high-voltage signals that must be 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 of up to 5 kVRMS according to VDE 0884-17 and UL1577, and supports a working voltage of up to 1 kVPK.

The device offers an open-drain and a push-pull output with a propagation delay of less than 320 ns. The integrated low-dropout (LDO) regulator supports an operating voltage range of 3 V to 27 V on the high-voltage side, allowing the comparator to be powered from a wide range of power supplies. The operating voltage range on the low-side is 2.7 V to 5.5 V.

The AMC23C10 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.

TIDA-050058 — 固態繼電器的零交叉切換參考設計

此參考設計展示如何以固態繼電器實現零交叉切換 (ZCS)。參考設計配備 TPSI3050-Q1 隔離開關驅動器。TPSI3050-Q1 裝置整合了層壓變壓器，在將訊號和電源傳輸至二次側時實現隔離。如此就不需要任何隔離偏壓電源。此外，TPSI3050-Q1 裝置可爲位於高電壓 (HV) 側的外部電路提供輔助電流 (IAUX)。ZCS 會在維持低電壓 (LV) 和 HV 側之間的訊號隔離情況下完成。此參考設計實現了具有 110-VRMS、60-Hz AC 電源的 12-V、200-µs 延遲 ZCS。
