YQS8069

PTC Resettable Fuses have long been used as a type of safety device in modern electronics. The YQS8069 is one example of such a fuse. This device is an integrated circuit (IC) designed for a wide variety of uses. It has the advantage of being easy to install and safe to use.

The YQS8069 application field is generally used for over-voltage, over-current, reverse current, over-temperature, and other current protection. Generally, the protection range can be adjusted to the required current. When the preset current exceeds the over current or reverse current set value, then the device will be triggered off and the PTC terminal can be reset after the circuit power is restored.

At the same time, the YQS8069 has the unique feature of low voltage maintaining, which means that the fuse can maintain a low voltage when the device is triggered off and provide a constant output, allowing the device to keep going even when the power is shut off. This makes it an ideal solution when the supply voltage is unstable.

The YQS8069 also has a variety of other features such as low impedance, fast response and self-diagnosis. Furthermore, it is extremely reliable since it is designed to withstand extreme temperature and humidity levels, and it is protected against static electricity and surge protection.

In terms of its working principle, the YQS8069 operates by sensing the current passing through the device, which is then compared against the preset current protection values. When the preset current threshold is exceeded, the device is triggered and the PTC terminals are reset once the circuit power is restored. This helps to protect the device against surges and other faults, ensuring that the device maintains its normal operation.

Overall, the YQS8069 is an integrated circuit with a variety of uses and features, making it an ideal choice for a wide variety of applications. Its low voltage maintaining, fast response, and self-diagnosis capabilities make it a reliable and safe choice.
