Introduction

The S-80825CNY-B2-U is a high-performance, low-power supervisor developed by Skyworks Solutions, Inc. It has a wide range of applications and provides high-performance, flexible monitoring functions that allow it to be used in a variety of power management applications.

Application Field

The S-80825CNY-B2-U is a versatile power management device that can be used in a variety of applications, including telecommunication systems, automotive systems, industrial control systems, and consumer devices. The device is capable of monitoring multiple supply voltages, providing over/under voltage protection and accuracy, and providing diagnostic functions. Additionally, the S-80825CNY-B2-U provides configurable pull-down resistor values to prevent “cold-start” voltage surges.The device is also capable of monitoring multiple digital signals. It supports up to seven digital input signals, including two 3.3V, two 5V, and one dual level digital input signal. This allows for monitoring of a wide range of digital signals and reducing false detection of power faults.

Working Principle

The S-80825CNY-B2-U supervisor operates using a power sequence method. It is designed to monitor multiple supply voltages and digital inputs to detect over/under-voltage conditions and potential issues with the power source.The S-80825CNY-B2-U is a low-power supervisor that utilizes a built-in signal conditioning system to ensure smooth and accurate operation. When power is applied or voltage levels drop or rise, the device’s internal software algorithm will monitor the critical supply voltages with a 0.5% accuracy. If the voltage exceeds the preset thresholds, an active reset output will be triggered to reset the system.The supervisor also has a number of diagnostic functions such as power failure, undervoltage lockout, supply voltage reduction and power down sensing. These features help ensure that the system is always running optimally and allow for adjustments to be made in the event of a fault.

Conclusion

The S-80825CNY-B2-U supervisor is a powerful, low-power solution for a wide range of power management applications. It offers a wide range of monitoring and protection functions, including the monitoring of multiple supply voltages and digital input signals, the ability to detect over/under voltage conditions, theconfigurable pull-down resistor functions, and various diagnostic functions. The device is equipped with robust signal conditioning and accuracy and is ideal for applications requiring high-performance and reliable power management solutions.
