Microchip - MCP39F511A電源監控IC



利用Microchip雙模式電源監控IC發揮最大系統效能 單顆IC為直流交流電源即時測量提供領先業界精確度水準。

在同時使用交流和直流電源的系統中，實現雙模式電源監控傳統上需要多個IC才能保證達到優越的效能和準確性。越來越多的應用，例如太陽能逆變器、智慧照明和雲端伺服器通常使用雙模式來保持安全運行，使用交流電作為主電源，直流電作為備用電源，或者反過來。為了優化效能，降低此類系統的開發難度。Microchip Technology Inc.推出靈活的雙模式電源監控IC，在測量交流和直流電源時，能在寬達4000:1的範圍內，達到領先業界的0.1%精確度水準。將電源計算和事件監控融入到一個IC中，降低了材料成本，並縮短了韌體開發時間。
