RTQ6053/RTQ6053B 是一款高精度電流感測監測器,具備 I<sup>2</sup>C 與 SMBus 介面,可透過讀取負載電流與功率提供完整系統資訊。此元件監測感測電阻兩端的壓降與 BUS 電壓,並透過內部類比數位轉換器 (ADC) 將這些量測值轉換為以安培表示的電流與以瓦特表示的功率。其整合可程式化校準、可調式轉換時間與平均功能,以提供更高的設計靈活性。RTQ6053/RTQ6053B 可在 −40°C 至 125°C 的寬溫度範圍內運作,並支援 2.7V 至 5.5V 的輸入電壓。此元件能夠在 0V 至 36V 的共模匯流排電壓下感測電流。其提供開汲極警示輸出以進行系統保護,使主機能在過電流、過壓或過功率狀況發生時接收警告。RTQ6053/RTQ6053B 採用小型 VQFN-16L 3x3 封裝。
