The INA216 is a high-side voltage output current shunt monitor that can sense drops across shunts at common-mode voltages from +1.8V to +5.5V. Four fixed gains are available: 25V/V, 50V/V, 100V/V, and 200V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale, or with wide dynamic ranges of over 1000:1.

These devices operate from a single +1.8V to +5.5V power supply, drawing a maximum of 25µA of supply current. The INA216 series are specified over the temperature range of –40°C to +125°C, and offered in a chip-scale package.

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。
