The S-80921CNNB-G8RT2G is a supervisor device that falls under the category of power management integrated circuits (PMIC). Usually abbreviated as PMICS, these power management circuits are a type of semiconductor integrated circuit (IC) dedicated to the efficient management of power. They come in various specifications and packages, but all of them serve the same purpose and that is to effectively manage and control power.

The S-80921CNNB-G8RT2G is mainly used for digital systems that require very low power and have a need for intelligent monitoring. It is most commonly integrated into field-programmable gate array (FPGA) and microcontroller-based systems. The device is applicable to any system that needs to monitor short or long duration input or outputs conditions.

The device\'s operating temperature range is from –40°C to +85°C and works by monitoring a specific logic threshold, usually set to 2.0V Vout, for a low-voltage system. It also watches for power supply transients and disables the system if it detects any irregularities. This ensures that the system is protected from damage due to an overload. In case of an overload, the device is automatically reset, and then resumes normal operations.

The S-80921CNNB-G8RT2G comes with a range of features that make it ideal for low-power applications. These features include two user-selectable undervoltage thresholds, two user-selectable watchdog timer settings, manual reset, power-on reset (POR), temperature-compensated reset (TCR) and windowed open drain reset output. Apart from these, the device also provides diagnostic feedback, overtemperature tracking and voltage-level detection.

The device has an open-drain active high output based on an internal logic circuit. The logic circuit detects a fault condition, such as an undervoltage threshold, and activates the reset output. This reset output is used to notify the system of an overload or some other fault, allowing the system to perform an orderly shut-down. This ensures that the system is not damaged due to an overload.

The S-80921CNNB-G8RT2G has a low-power consumption of below 0.1 microamp, making it ideal for battery-operated applications. In addition, it is highly reliable due to its RoHS-compliant construction and its electrostatic discharge (ESD) rating of 10KV.

The S-80921CNNB-G8RT2G is a highly-effective monitor ideal for applications that require intelligent power management. It provides a wide range of features, such as user-selectable thresholds, watchdogs, reset functions, and diagnostic feedback, all of which enable it to monitor power supply transients while protecting against overloads and other fault conditions.
