Power Management Integrated Circuits (PMICs) are essential components for power handling solutions in many fields. Among them, Supervisors are special PMICs that are designed to monitor the power rail and reset the system in the case of powerfailure, under/over-voltage and over-temperature conditions. In this article, we will discuss the field of application and working principle of one particularexample of supervisors – the S-80915CNNB-G8KT2G.

The S-80915CNNB-G8KT2G is a supervisor IC developed by Renesas Electronics America. It is designed for resetting and detection applicationfor micro-controller and digital logic ICs. This IC uses a combination of manual and serial interface for reset control and features an on-chippower-on reset circuit, an open drain reset output, an open drain power good (PG) output and a reset status flag. It also features an input reference voltage pin that is typically used to adjust the reset voltage threshold to fit the needs of a specific system.

Since the S-80915CNNB-G8KT2G supervisor IC is intended for resetting and detection applications, one of its main use cases is for applications that require an accurate reset signal. This could be in the form of a hard reset that occurs every time the power fluctuates, or a soft reset that occurs when certain conditions are met. In addition, this IC can also be used in applications that require reliable system reset signals in order to avoid data loss and system crashes due to power failure.

When it comes to the working principle of the S-80915CNNB-G8KT2G supervisor IC, it works by monitoring the voltage level of the system’s main power rail. If any sudden changes occur in the power rail such as a power failure, an over-voltage or under-voltage condition, the IC sends out a reset signal. This reset signal is either in the form of a hard reset flag or a soft reset flag, depending on the specific system’s configuration. Furthermore, in the case of critical failure conditions, the PG output of the IC also signals to other devices in the system that the system needs to perform a reset operation.

In conclusion, the S-80915CNNB-G8KT2G is a supervisor IC that is designed for resetting and detection applications in micro-controller and digital logic ICs. Its main job is to monitor the voltage level of the system’s main power rail, and if any sudden changes occur in the power rail, it sends out a reset signal. In addition, this IC also features other useful features such as an open drain reset output, an open drain power good (PG) output and a reset status flag. As such, this supervisor IC is useful for applications that require an accurate reset signal or a reliable system reset to avoid data loss and system crashes due to power failure.
