IC PROTECTION CIRCUIT, METHOD FOR PROTECTING IC, AND APPARATUSES HAVING THE IC PROTECTION CIRCUIT |
摘要 |
An electronic device includes a power supply line connected between a DC power supply and an integrated circuit, and a first electronic element and a second electronic element serially connected between the power supply line and ground. The second electronic element is open when the first electronic element is short-circuited due to an overvoltage induced in the power supply line. When the overvoltage exceeds a breakdown voltage of the first electronic element, the first electronic element supplies an overcurrent induced in the power supply line to the second electronic element.
