Abstract

Hot-plugging refers to attaching a powered up voltage source to the input power or battery connector of an electronic device. Voltage transient spikes from hot-plugging can damage the integrated circuits inside the device. This application note explains the root cause for these voltage transients and provides potential designs to prevent these transients from damaging the integrated circuits (ICs) in the electronics.
