Power Management Integrated Circuits (PMIC) are devices used to control the power dissipation and distribution of integrated circuits. A variety of voltage and current sources, as well as various digital and analog signals, can be managed with a single PMIC. Supervisors, a subcategory of PMICs, are devices used to monitor system conditions for use in advanced power management applications. S-80955CNMC-G9RT2U is a supervisor device, specifically designed to detect power interruptions and to protect from over-voltage conditions.

The S-80955CNMC-G9RT2U monitors system power, reset, and program current functions, and is designed as a system supervisor with a low-value microcontroller reset and polarity protection circuit. It has a wide operating voltage range of 2.6 V to 5.5 V. It is designed to trigger a reset to the device when the input voltage is below the trip point, and to enable shut-down protection when the input voltage exceeds the trip point. This supervisor device can also protect peripherals in voltage-sensitive applications.

The S-80955CNMC-G9RT2U features an internal voltage regulator circuit, allowing it to be powered from an external source or from the microcontroller voltage rail. It also contains a wide hysteresis trip point for reset/shut-down and a minimum reset pulsewidth to prevent spurious resetting. For resetting applications that make use of AND gates, a reset active output is provided.

The S-80955CNMC-G9RT2U can monitor a variety of different power sources, including 3-state supply voltage, lithium-ion battery voltage, 2-state supply voltage, VCC_AUTO pin, and ESD/DC protection circuit. It also has a low-voltage comparator to detect low-voltage operations and to ensure reliable operation in active and sleep modes. The integrated circuit can detect power supply failures and provide an output to notify the system.

In terms of its working principle, the S-80955CNMC-G9RT2U compares the voltage level of the power supply to an adjustable trip point. If the voltage is below the trip point, the device will issue a reset signal. If the voltage is above the trip point, the device will shut down the system. This allows for robust protection against over-voltage conditions, which can damage equipment and lead to system failure. The device is also capable of providing feedback to the system in the form of a logic output to indicate system power status.

The S-80955CNMC-G9RT2U supervisor device is ideal for use in a variety of applications, such as LCD panels, LED lighting systems, DC/DC power regulators, wireless communication systems, automotive control systems, and consumer electronic devices. In addition, the device is also suitable for use in high-power applications, including industrial automation and medical systems where reliable power management is required.

The S-80955CNMC-G9RT2U supervisor device is a cost-effective, reliable solution for advanced power management systems. Its wide operating voltage range, programmable trip point and reset pulsewidth, and reset/shut-down management combine to make this device a powerful tool for managing power in modern applications. The device\'s extensive features make it suitable for a variety of industrial and consumer applications.
