The S-80927CNPF-G8XTFU is a supervisor circuit that monitors the voltages and currents of the power supply in any electronic system. It is part of the larger Power Management Integrated Circuit (PMIC) family and is usually used to ensure that the power supply operates within a certain voltage range. It is a versatile device that is used in a variety of applications in consumer products, industrial equipment, and automotive systems. In this article, we will explore the application field, important features, and working principle of the S-80927CNPF-G8XTFU.

Application Field

The S-80927CNPF-G8XTFU is a valuable asset when it comes to power system design and is commonly used in consumer electronics, industrial equipment, and automotive systems. The supervisor circuit helps to guarantee that the system operates within certain voltage ranges and that the power draw is kept to acceptable levels. It is an often-overlooked element of the power supply design as it is not typically the primary source of power, but its importance should not be underestimated.

The S-80927CNPF-G8XTFU is typically used in applications that require frequent monitoring and/or system resetting/shutdown. For example, it can be used in situations when the system must be reset in the event of an overload, or when unpredictable power glitches occur. It is also often used in portable devices that cannot easily be powered by a wall outlet, such as laptops or phones, as it can help to maintain the system ever-present power supply.

Important Features

The S-80927CNPF-G8XTFU is a highly versatile supervisor circuit and it can be used to monitor many different voltages and currents. Some of its most important features include its ability to monitor up to 8 individual voltages, as well as to measure, monitor, and compare the total system power. It also has a wide range of reset and shutdown options, and can be programmed to respond in various predetermined ways in the event of an over or under voltage.

Another key feature of the S-80927CNPF-G8XTFU is its relatively low power consumption of 1uA typical and 10uA maximum. This makes it suitable for use in systems where power conservation is important, and it ensures that the power draw of the supervisor circuit itself is kept to a minimum. Additionally, its low supply voltage of 2.2V to 5.5V enables it to be used in a wide range of systems.

Working Principle

The basic working principle of the S-80927CNPF-G8XTFU is relatively straightforward. The circuit monitors the voltages and currents of the power supply in the system and increases its power draw to compensate for any abnormal fluctuations. It will then compare the current power level to its predefined trip point and if the power levels exceed this point, it will initiate a reset or shutdown. Additionally, the circuit can be programmed to take other actions such as applying a voltage brown-out signal, or activating a protective circuit, in order to respond more effectively to power supply irregularities.

Conclusion

The S-80927CNPF-G8XTFU is a versatile supervisor circuit that is used in a variety of applications in consumer electronics, industrial equipment, and automotive systems. It is capable of monitoring the voltages and currents of the power supply, as well as activating reset/shutdown operations according to preset trip points. Its low power consumption and wide supply voltage range make it an ideal choice for power system design, and its robust design ensures reliable and accurate monitoring of system power. It is an important part of the larger PMIC family and should not be overlooked.
