(1) Custom temperature ranges

The INA271 is a current-shunt monitor with voltage output and can sense drops across current shunts at common-mode voltages from –16V to +80V, independent of the supply voltage. The INA271 pinouts readily enable filtering.

The INA271 is available with a 20V/V output voltage scale. The 130kHz bandwidth simplifies use in current-control loops.

The INA271 operates from a single +2.7V to +18V supply, drawing a maximum of 1600µA of supply current. This device is specified over the extended operating temperature range of –55°C to +210°C.

CIRCUIT060035 — 具有窗型比較器電路的雙向電流感測

此雙向電流感測解決方案採用電流感測放大器與高速雙比較器，並具備軌對軌輸入共模範圍，可在比較器輸出 (OUTA 和 OUTB) 處建立過電流 (OC) 警示訊號，如果輸入電流 (IG1) 高於 100 A 或降至 -35 A 以下。在此實作中，兩個過電流警示訊號都是高電位作動，因此當超過 100 A 或 -35 A 閾值時，比較器輸出將會變高。在兩個比較器上實作外部磁滯，因此當電流降低 10% (90 A 和 -31 A) 時，比較器輸出將回到邏輯低狀態。雖然下方電路將分流電阻器 R8 連接至接地，但相同的電路仍適用於高壓側電流感測，最高可達 INA 的共模電壓範圍。

CIRCUIT060037 — 精密過電流閂鎖電路

這個高壓側電流感測解決方案採用電流感測放大器、含整合式參考的比較器以及 P 通道 MOSFET，以建立過電流閂鎖電路。當偵測到負載電流大於 200 mA 時，電路會中斷系統與電源的連接。比較器輸出將閂鎖 (將 P 通道 MOSFET 的閘極電壓保持在 0 V)，直到電路的電源開始循環，因為比較器會驅動 P 通道 MOSFET 的閘極，並將訊號傳送回電流感測放大器的參考針腳。
