The LM2902-Q1, LM2902B-Q1, and LM2902BA-Q1 are industry-standard operational amplifiers that have been qualified for automotive use in accordance to the AEC-Q100 specifications. The LM2902B-Q1 and LM2902BA-Q1 are the next-generation versions of the LM2902-Q1, which include four high-voltage (36V) operational amplifiers (op amps). The LM2902B-Q1 and LM2902BA-Q1 provide outstanding value for cost-sensitive applications, with features including low offset (3mV and 2mV maximum, respectively), common-mode input range to ground, and high differential input voltage capability.

The LM2902B-Q1 and LM2902BA-Q1 simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage of 0.3mV (typical), and lower quiescent current of 240µA (typical). High ESD (2kV, HBM) and integrated EMI and RF filters enable the LM2902B-Q1 and LM2902BA-Q1 devices to be used in the most rugged, environmentally challenging applications for the automotive marketplace.

CIRCUIT060074 — 具有比較器電路的高壓側電流感測

此高壓側電流感測解決方案使用一個具有軌對軌輸入共模範圍的比較器，若負載電流上升到 1 A 以上，便在比較器輸出 (COMP OUT) 建立過電流警示 (OC 警示) 訊號。此實作中的 OC 訊號為低電位作動。因此當超過 1-A 閾值時，比較器輸出會變低。實作磁滯後會在負載電流降低至 0.5 A (減少 50%) 時，讓 OC-Alert 返回邏輯高狀態。此電路利用開漏輸出比較器，為控制數位邏輯輸入針腳而進行電平轉換輸出高邏輯電平。對於需要驅動 MOSFET 開關閘極的應用，建議使用具推挽輸出的比較器。
