具有輸出電流監(jiān)控功能的 14V、25A 同步降壓功率級

UCD74120 是一款多芯片模塊，此模塊在耐熱增強型緊湊，5mm x 7mm，QFN 封裝內(nèi)集成了一個驅(qū)動器器件和兩個 NexFET 功率 MOSFET。 25A 輸出電流能力使得此器件適合為 DSP 和 ASIC 供電。 此器件被設(shè)計成為數(shù)字或模擬 PWM 控制器提供補充。 驅(qū)動器器件的 PWM 輸入是三態(tài)兼容的。 兩個驅(qū)動器電路可在同步降壓電路中為高側(cè) N 通道 FET 開關(guān)和低側(cè) N 通道 FET 同步整流器提供高充電及放電電流。輸出電流由一個用于處理外部電流感測元件上電壓的精密電流感測放大器進(jìn)行測量并監(jiān)視。 IMON 引腳上的 PWM 控制器能夠使用這個被放大的信號。 板載比較器監(jiān)視 ? 集成同步降壓驅(qū)動器和 NexFET 功率金屬氧化物半導(dǎo)體場效應(yīng)晶體管 (MOSFET) 技術(shù)用于實現(xiàn)高功率密度和高效率\n? 輸入電壓范圍 4.7V 至 14V \n? 內(nèi)置高側(cè)電流保護\n? 與負(fù)載電流監(jiān)視器輸出成比例的電壓\n? 欠壓閉鎖 (UVLO) 管家電路\n? 40 引腳，5mm x 7mm，塑料四方扁平無引線 (PQFN) 封裝 PowerStack 封裝;
