This article provides an overview of the S-80818CLY-B2-U application field and working principle.

The S-80818CLY-B2-U has been optimized for automotive systems induced by chemical activity, high-temperature environments and ignition noise. It provides protection between the VPWR supply and the processor by preventing the host processor from being damaged by overvoltage and excessive current. Some of the features of the S-80818CLY-B2-U include:

• Input voltage range 4.3V to 44 V DC
• Voltage monitor voltage range 4.3V to 42 V DC
• Output current up to 2 A
• Readable voltage thresholds
• Ultrasmall SOT-23-5L packaging
• ESD protection over 1 kV

The S-80818CLY-B2-U support a wide input voltage range and is designed to protect against over-voltage and under-voltage situations. This protection circuit can detect the voltage of a power supply over a wide range and initiate an appropriate response. It can also detect an over-voltage or under-voltage condition, and initiate an appropriate response to prevent the damage of any system component.

The primary function of the S-80818CLY-B2-U protection circuit is to provide system protection from over current, over voltage, under voltage, over temperature and electrostatic discharge (ESD). It also provides read voltage threshold and selectable delay times. The integrated protection circuit of the S-80818CLY-B2-U can detect any over-voltage and under-voltage conditions. System diagnostics including current, voltage and temperature monitoring are also provided by the S-80818CLY-B2-U.

In addition to the protection circuit, the S-80818CLY-B2-U also offers various voltage monitor outputs. These outputs can be used to monitor the voltage in the system and obtain a fast response in the case of an over-voltage or under-voltage condition. The S-80818CLY-B2-U provides a wide range of voltage monitor outputs and allows adjustable voltage thresholds for improved accuracy.

The S-80818CLY-B2-U also includes an adjustable current limit protection feature. This feature allows the user to limit the output current to a certain value, so that no single component or system can be damaged by an excessive current. This feature is especially important when the system is subjected to transient over-current surge, as no single component is damaged by the excessive current.

The S-80818CLY-B2-U also provides protection against over-temperature conditions. This feature will activate the protection feature once the temperature exceeds a certain threshold and will cut off the power to any system components that might be damaged by the heat.

Finally, the S-80818CLY-B2-U also provides electrostatic discharge (ESD) protection. This feature helps to protect devices from the electrostatic discharge, which is one of the potential causes of system failure. The ESD protection of the S-80818CLY-B2-U allows for the protection of up to 1kV of current.

In conclusion, the S-80818CLY-B2-U is a highly integrated protection circuit with a wide range of automotive protection features. It is an ideal solution for a range of applications that require reliable, efficient, and robust automotive protection. It offers various voltage monitor outputs, adjustable current limit protection, and over-temperature protection. In addition, it also provides electrostatic discharge protection. With its comprehensive feature set, the S-80818CLY-B2-U can help protect your automotive electronic systems against destructive load dumps and overvoltage situations.
