<p>The present invention, used for the prevention of the unwanted l2C read/write operations in the circuit elements connected to the l2C (inter integrated circuit) data line or supply voltage line (Vcc) due to voltage irregularities or the noises in the data line or supply voltage line (Vcc) monitors the voltage level of the data line or supply voltage line (Vcc) continuously, and it grounds the serial clock line (SCL) when the voltage level drops below a certain level, and releases it if the voltage level rises above the threshold value. The threshold voltage value can be adjusted for the circuit elements connected to the data line or supply voltage line (Vcc), and the unwanted read/write operations are prevented.</p> |
