Power management integrated circuits (PMICs) play an important role in controlling and regulating the flow of energy throughout a circuit board. PMICs are specifically designed to ensure that the system maintains a stable and reliable power supply. In addition, they can be used to manage power in applications such as battery charging, power conservation, and fault protection.

Supervisors and voltage monitors are a type of power management IC that serve as a watchdog over integrated circuit systems, ensuring that they operate safely. The S-80940CNNB-G9AT2G is a supervisor IC that is often used in systems that require a reliable, highly accurate voltage monitoring solution. This IC provides an on-chip voltage monitoring circuit with an active low enable pin and an open-drain output.

The S-80940CNNB-G9AT2G is primarily used in consumer applications, especially in microprocessor-based system designs, to monitor the supply voltage for any overvoltage or undervoltage conditions. It is typically used to detect low power supply voltages, including voltage drop-outs and brown-out events. It is also used in handheld applications to regulate supply voltages and ensure a stable power source. In addition, it can protect the system from sudden surges in voltage.

One of the major advantages of the S-80940CNNB-G9AT2G is its wide operating temperature range. It is capable of operating over a wide range of temperatures, from -40 to +85 degrees Celsius. This makes it suitable for use in automotive and industrial applications. The device also offers high accuracy and low power consumption, making it highly efficient in low-power systems.

The S-80940CNNB-G9AT2G is based on a master-slave control architecture. It has two distinct control modes: the monitor mode and the reset mode. In the monitor mode, the device continuously monitors the supply voltage. When the voltage exceeds the upper threshold voltage, the device outputs an active low signal. When the voltage drops below the lower threshold voltage, the device triggers a reset signal. In the reset mode, the device outputs a reset signal when it detects an overvoltage or undervoltage condition.

The S-80940CNNB-G9AT2G is a versatile power management IC that can be used in applications such as battery monitoring, overvoltage protection, undervoltage protection, and brown out protection. It is designed to monitor the supply voltage for any overvoltage or undervoltage conditions, protect the system from sudden surges in voltage, and ensure a stable power source. It is highly accurate, has a wide operating temperature range, and consumes very low power, making it a great choice for use in low-power applications.
