  • Protection circuit and operating method thereof
    Patent number: 8222700
    Abstract: A semiconductor component including a semiconductor substrate, a doped well formed in the semiconductor substrate, transistor structures arranged in the doped well, and an integrated circuit connected to the doped well, wherein the integrated circuit intermittently charges the doped well to a provided electrical potential, ascertains a deviation of the potential present at the doped well from the provided potential, and triggers an alarm signal in the event of a specific deviation.
