The ISOW784x is a family of high-performance, quad-channel reinforced digital isolators with an integrated high-efficiency power converter. The integrated DC-DC converter provides up to 650 mW of isolated power at high efficiency and can be configured for various input and output voltage configurations. Therefore these devices eliminate the need for a separate isolated power supply in space-constrained isolated designs.

TIDA-00847 — 採用具有整合電源的數位隔離器且尺寸和成本經最佳化的二進位模組參考設計

此參考設計僅使用兩種產品簡化系統設計，為 4 通道 DC 輸入二進位模組展示空間與成本最佳化架構，並具備改良的測量準確度與狀態指示。MCU 型二進位模組可改善二進位輸入的量測解析度，進而提升系統性能，提供準確且可重複的故障指示，並可省去對多個硬體版本的需求 (對多個額定電壓輸入使用相同設計)。這減少了設計、測試、製造和現場支援工作。在此設計中，4 輸入通道配置為群組隔離輸入，以將每通道成本降到最低。10 位元類比轉數位轉換器 (ADC)，可在廣泛範圍中測量 ±3% ±1-V 範圍內的 DC 輸入準確度。已針對 EMI 和 EMC 執行預先相容測試。
