Application Fields of MN13822SJP

The MN13822SJP is ideally suited for a wide range of applications, due to its advanced features and extended voltage range. The device is commonly used in embedded systems, automotive systems, high-end medical applications, and industrial process control systems. This supervisor is also suitable for use in power supply monitoring, battery monitoring, and power-up sequencing.

Working Principle of MN13822SJP

The MN13822SJP operates using a two-stage control system. The first stage is the voltage comparison stage, where the input voltage is compared with the internal reference voltage. If the input voltage is below the reference voltage, the device will initiate a reset. The reset delay time is configurable and can be set to a value between 0ms and 1s. The reset state is driven until the input voltage rises above the predetermined reset threshold. The second stage is the reset assertion stage, where the output is driven low and the reset state is asserted. The reset assertion time is adjustable and can range from 0ms to 3s. When the reset assertion time has elapsed, the device will de-assert the reset and drive the output high.

In order to ensure the device’s accuracy and reliability, the MN13822SJP is subjected to a number of qualification testing procedures. These include tests for input power supply voltage change over temperature, input voltage accuracy, reset assertion time, reset delay time, and ground current stability.

Conclusion

The MN13822SJP offers an excellent choice for a variety of applications that require precision, reliability, and quick response time. The device offers accurate voltage sensing and a configurable reset and reset timing functions. Its impressive features make it a popular choice for applications such as embedded systems, automotive systems, high-end medical applications, and industrial process control systems. The device also has a wide operating voltage range and is highly reliable even in extreme temperature ranges.
