As the types of electronic digital products and consumer household appliances continue to grow, the laws and regulations on the power interfaces of related electronic equipment have not been synchronized; each manufacturer has its own interface standards; for low-voltage power supplies, anti-misplugging, anti-reverse plugging, and related question, yint provides low voltage power supply protection solution.

 

5.0V power line protection solution

Reason for protection: 5V circuit of external equipment, commonly used methods: circular connector, 3.96 male and female plug, non-standard red and black wiring; easy to access similar 9V, 12V power plugs, and the 5V power supply is simply filtered and directly connected to the single Various types of ICs, such as chips, are extremely susceptible to damage by surges.

Fig.1

Device selection:
1) PPTC overcurrent abnormal protection, is divided into two types according to packaging: plug-in and patch; its maximum withstand voltage must be higher than 5V, with options of 6V, 8V, 16V, 30V, and 60V, the device nominal The current IH must be greater than or equal to the normal stable operating current of the power circuit.


2) TVS diode, overvoltage abnormality protection, is divided into two types according to packaging: plug-in and patch; it mainly targets the peak surge voltage damage generated during the plug-in process and is also very helpful for EMC testing. For example 5V power supply, normal working current I: 1.0A. Temperature and atmospheric pressure are the normal usage conditions. PPTC is generally easy to plug into the wrong 9V or 12V power supply. Consider the 16V device's withstand voltage. Then consider the packaging form. If the PCBA is relatively compact and highly Restricted, use SMD packaging! In addition, consider the disassembly factors of the device due to the operating temperature.


TVS considers general 5V/1A power supply, relatively low power, and uses 600W peak power devices

12.0V power line protection solution

Reason for protection: 12V circuit of external equipment, commonly used methods: circular connector, 3.96 male and female plug, non-standard red and black wiring; easy to access similar 9V, 12V power plugs, and the 12V power supply is simply filtered and directly connected to the single ICs such as chips are extremely susceptible to damage from surges.

The nominal current IH of the device must be greater than or equal to the normal stable operating current of the pow


2) TVS transient suppression diode, overvoltage abnormality protection, is divided into two types according to packaging: plug-in and patch; it mainly targets the peak surge voltage damage generated during the plug-in process, and is also very helpful for EMC testing. For example 12V power supply, normal working current I: 1.0A. Temperature and atmospheric pressure are the normal usage conditions. PPTC is generally easy to plug into the wrong 18V or 24V power supply. Consider the 30V device's withstand voltage; then consider the packaging form. If the PCBA is relatively compact and highly restricted, use SMD packaging! In addition, consider the disassembly factors of the device due to the operating temperature.


TVS considers a general 12V/1A power supply, relatively low power, and uses 600W peak power devices.

Device selection:
1) PPTC self-restoring fuse, over-current abnormal protection, divided into two types according to packaging: plug-in and patch; its maximum withstand voltage must be higher than 24V, 60V option, the nominal current IH of the device must be greater than or equal to the normal stable operating current of the power circuit.


2) TVS transient suppression diode, overvoltage abnormality protection, is divided into two types according to packaging: plug-in and patch; it mainly targets the peak surge voltage damage generated during the plug-in process, and is also very helpful for EMC testing. For example 24V power supply, normal working current I: 1.0A. Temperature and atmospheric pressure are the normal usage conditions. PPTC generally makes it easy to insert the wrong 28V or 36V power supply. Consider the 30V device's withstand voltage; then consider the packaging form. If the PCBA is relatively compact and highly restricted, use SMD packaging! In addition, consider the disassembly factors of the device due to the operating temperature.

36V power line protection solution

Reason for protection: 36V circuit of external equipment, commonly used methods: round connector, 3.96 male and female plug, non-standard red and black wiring; easy to connect to similar 48V power plug. Moreover, the 36V power supply undergoes simple filtering and is directly connected to various ICs such as a single chip, which is easily damaged by surges.

Device selection:
1) PPTC self-restoring fuse, over-current abnormal protection, divided into two types according to packaging: plug-in and patch; its maximum withstand voltage must be higher than 24V, 60V option, the nominal current IH of the device must be greater than or equal to the normal stable operating current of the power circuit.
