PMIC, or Power Management Integrated Circuit, has become an indispensable component in the modern electronic system. PMIC have a variety of functions, from voltage monitoring, signal conversion, to power regulation and control. One of the most important types of PMIC, Supervisors offer an additional layer of protection and reliability to the system. They help guard against the erratic behavior of the rest of the system components during power loss or signal glitches. The S-80138ALMC-JAXT2U is a lightweight system supervisor IC intended for a wide range of applications.

Applications of S-80138ALMC-JAXT2U

The S-80138ALMC-JAXT2U is perfect for applications that require fast start-up and low voltage operation. It is compatible with various PMIC and is suitable for use in portable, battery-powered devices. It is also ideal for always-on low power applications where conventional microcontrollers require the use of higher and more expensive voltage supply. Another great application to which it can be applied is for memory write protection on embedded systems. The S-80138ALMC-JAXT2U can be used as a supervisor to prevent unintentional writes to protected memory, meaning sensitive and important data can be easily secured.

Working Principle of S-80138ALMC-JAXT2U

The S-80138ALMC-JAXT2U employs three key features to provide the added protection. First, it has a low quiescent current operation (IAS) which, in practice, implies that the device is already performing system supervision when it’s still in the off state. Second, it has a low voltage supervisor that works to keep the power supply voltage within tolerance. This helps prevent irregular behavior in the connected devices, like a sudden surge or drop in voltage levels. Lastly, it has an open drain reset signal that allows the system to revert to a predefined state to prevent further abnormal behavior. This reset signal is connected to the reset pins of other devices in the system, meaning that it can be used to reset the entire chain of components.

Conclusion

The S-80138ALMC-JAXT2U is designed to provide superior system protection against sudden power loss and signal glitches. It is essential for applications where power is essential, from embedded systems or portable devices to battery-powered devices. With its low quiescent current, low voltage supervisor and open drain reset signal, it is an ideal choice for added reliability and protection.
