上海南芯限流集成SC7004,SC7004SAER充電端口控制器
The SC7004 is a power switch which integrates an ultra-low Rdson (12mΩ) N-channel MOSFET. It is designed for USB port applications or other applications which require high current switch. It provides current limit function, and the current limit can be programmable through an external resistor. The SC7004 also integrates USB charging port cooller function. It can support traditional type A USB port with DP and DM signals. It monitors the DP/DM data line voltage, and automatically supports the DCP schemes for Battery Charging specification (BC1.2), the divider Mode and 1.2V/1.2V Mode.
SC7004典型應(yīng)用電路:
SC7004提供兩個獨立的熱傳感模塊,在恒流模式和負載開關(guān)模式下監(jiān)測結(jié)溫。
當(dāng)SC7004在恒流模式下工作時,如果輸出電壓保持在3.8V以上,IC會保持開關(guān)的導(dǎo)通。在這種情況下,電源開關(guān)上會有很大的電壓降,從而導(dǎo)致高散熱。一旦SC7004檢測到結(jié)溫上升到140°C以上,它就會關(guān)閉開關(guān);當(dāng)它檢測到溫度下降到115°C以下時,它會通過軟啟動過程再次打開開關(guān)。
