Create reliable IoT products through circuit protection design technology

The Internet of Things (IoT) connects many different devices that collaborate for the purpose of collecting and sharing data. Such threats to the ecosystem are likely to occur, such as the risk of system failure caused by various over-current, overheating, static electricity (ESD) and electromagnetic pulse (EMP) in addition to environmental conditions. Therefore, it is absolutely necessary to adopt mitigation measures to ensure a high level of reliability. Expectations for IoT infrastructure. Product designers are mainly concerned about the function and performance of equipment, but as more and more equipment are included in the IoT infrastructure, it is crucial to include circuit protection technology in the product design cycle.

Internet embedded computing solutions and platforms for IoT applications. These solutions use extremely compact hardware and have a multilayer HDI PCB design for high-speed digital and mixed signal systems. In order to maintain the high reliability expected by these IoT systems, circuit protection is a crucial design goal.

Here are some key protection technologies:

ESD diode/array can provide protection for I/O port to prevent transient caused by electrostatic discharge (ESD), electrical fast transient (EFT) and other induced voltages.

EMI suppression filter can reduce high-frequency electromagnetic noise transmitted through conduction, which may cause interference to other equipment.

Temperature sensors/thermistors/thermistors help monitor system and chip temperatures. If a predetermined threshold is exceeded, this enables the system software to trigger a fault indication interrupt. Combined with Qualcomm's built-in thermal management algorithm running on its processor, it can ensure that the thermal management on the system is foolproof.

Hot plug controllers help safely remove and insert modules from the live backplane/server, and provide continuous protection against short circuit and overcurrent failures.

The programmable voltage monitoring circuit helps monitor the desired voltage level at a specific location in the system. If the monitored value exceeds a predetermined threshold, this will enable the system software to trigger a shutdown/power cycle/reset as needed.

The low resistance fuse (overcurrent protection) provides overcurrent protection for the circuit.

Transients in the circuit will rise rapidly, resulting in voltage spikes. These spikes must be prevented from appearing on precision electronic circuits and components. Varistors/thyristors (overvoltage protection) protect the circuit from sudden spikes exceeding predetermined limits.

For safety, discharge resistor must be used to release the charge stored in the filter capacitor of the power supply when turning off the power supply of the equipment.

The current limiting circuit limits the current from the regulated power supply to the maximum current determined by the circuit. These circuits are essential to provide protection in the event of short circuits or other accidental overloads.
