摘要：
An electronic circuit (200) for a portable electronic device includes an energy source interface (202), a load (204) coupled to the energy source interface (202), an energy storage circuit (206) having a maximum operating voltage, and a switch circuit (208). The switch circuit (208) is coupled to the energy source interface (202) in series with the energy storage circuit (206). The switch circuit (208) operates to switchably decouple the energy storage circuit (206) in response to a voltage at the load (204) that exceeds the maximum operating voltage.
