詳細(xì)描述
NJW4119 專為便攜式設(shè)備的 USB 充電而設(shè)計(jì)，可提供 2.4 的保證。它具有電纜壓降校正電路，可根據(jù)通過(guò)長(zhǎng)電纜連接的終端設(shè)備的輸出電流按比例校正輸出電壓。
附加功能包括過(guò)流保護(hù)、熱關(guān)斷、軟啟動(dòng)以及帶有延遲電路和電源良好指示器的錯(cuò)誤標(biāo)志輸出。
The NJW4119 is designed for USB charging of portable equipment and can supply 2.4 guaranteed. It features a cable drop voltage correction circuit that corrects the output voltage in proportion to the output current at the terminal device connected through a long cable.
Additional functions include over current protection, thermal shutdown, soft start, and an error flag output with delay circuit and power good indicator.
