负载开关反向电流保护 Reverse Current Protection in Load Switches
资料介绍
Reverse current is when there is a higher voltage at the output of a system than at the input, causing current to flow backwards through the system. There are two common sources of reverse voltage: (1) when power is disconnected from a system and (2) when the body diode of a FET becomes forwardbiased. One source is when system input power is disconnected, a higher voltage can be left at the output, which temporarily produces reverse current. Reverse voltage should not be confused with negative voltage (also known as reverse polarity). Negative voltage occurs in situations where the positive and negative terminals of a power supply are switched. In this case, what should be connected to ground actually has a voltage from the positive input to the system. This causes a different current phenomenon through the part than reverse voltage.
