電源和保險絲狀態輸出組合成一個雙光隔離器設計電路

使用 Analog Devices 的 LTC1921 的參考設計

設計簡介

電源和保險絲狀態輸出組合成一個雙光隔離器設計電路。可靠性是現代電話和通信設備設計者的首要任務。設計人員特別注意通過盡可能采用冗余來保護電路免受故障，特別是對于電源。通常通過一系列復雜的精密組件來監控電源電壓和保險絲，以對即將發生的故障發出早期警告

Supply and Fuse status outputs combined into one dual Opto-Isolator Design Circuit. Reliability is a top priority for the designers of modern telephone and communications equipment. Designers take extra care to protect circuitry from failure by employing redundancy whenever possible, especially for power supplies. Supply voltages and fuses are monitored for early warnings of impending failure, often via a complicated array of precision components
