TPS2549 | 具有電纜補償功能的 USB 汽車類充電端口控制器和 3A 電源開關(guān) TPS2549 器件是一款 USB 充電端口控制器和電源開關(guān),其帶有可控制上行電源的電流感測輸出。該器件可使 USB 端口電壓維持在 5V 水平,即使 充電電流過大也依然有效。這對于 USB 電纜較長的系統(tǒng)而言至關(guān)重要,因為該系統(tǒng)在對便攜式設(shè)備進(jìn)行快速充電的過程中會產(chǎn)生大幅壓降。 TP2549 47mΩ 電源開關(guān)具有兩個可選的可編程電流限值,可通過在相鄰端口承載高負(fù)載時提供較低電流限值來支持端口電源管理。這對于具有多個端口并且上行電源無法同時為所有端口提供滿載電流的系統(tǒng)而言至關(guān)重要。 DCP_Auto 方案通過檢測并選擇合適的 D+ 和 D– 設(shè)定與所連設(shè)備進(jìn)行通信,以便在滿載電流條件下完成快 ? 4.5V 至 6.5V 的工作范圍\n? 最大連續(xù)開關(guān)電流達(dá) 3A\n? 充電下行端口 (CDP) 模式符合 USB 電池充電規(guī)范 1.2\n? 短路模式符合 BC1.2 和 YD/T 1591-2009\n? 1.2V 模式\n? 面向系統(tǒng)更新的 D+ 和 D– 客戶端模式\n? D+ 和 D– ±8kV 接觸放電和 ±15kV 空氣放電 ESD 額定值 (IEC 61000-4-2)\n? 運行結(jié)溫范圍:-40°C 至 125°C\n? 16 引腳 3mm x 3mm 四方扁平無引線 (QFN) 封裝; | TI 德州儀器 | TI | |
