摘要：
An electronic device with an amplifier output stage (OS) and an over-current detection means (OCDM) for detecting an output over-current (IHS, ILS) of the output stage (OS) is provided. The over-current detection means (OCDM) comprises a level detection means (LDM) for detecting a level of the output current (IO) exceeding a first level of the output current (IDET), and a timing detection means (TDM) for detecting a duration during which the output current (IO) exceeds the first current level (IDET) being a maximum current level.
