When developing simulation electronic products, attention should be paid to the selection of chip temperature dependent MCU. The concept ranges from 7GHz to MHz operating frequency. Due to the parasitic resistance and other noise limitations that need to be met by the input and output of ordinary IO pins, and the maximum noise generated based on simulation results, the relationship between electronic products and technology can be understood. At this time, the voltage and current of the power module peripherals become affected by external interference, which means that the component must be shielded, especially to ensure that the ESD protection device itself is not damaged.
At the same time, it is necessary to achieve electrical protection. ESD is caused by the formation of a circuit between the isolation part and the circuit. Therefore, it is very important to install an RC absorption circuit between the ESD protection circuit and the communication circuit.
As shown in the above figure, the interference source is adjacent to T1 and T2 on the PCB board, so the grounding noise on the two PCB boards needs to be reasonably suppressed. It is only effective to add capacitance to the power supply ground using T1 and T2. This parasitic capacitance is a transient for high current, usually output in the form of high-frequency inductance and small current.
