Power management circuits (PMICs) play an important role in many electronic circuits, including PCs, communication systems, and power engineering systems. In particular, PMICs are capable of regulating the voltage and current delivery in the system, and providing power protection, control and monitoring. Among such PMICs, supervisors are special ICs that are used to control and monitor the overall circuits in an electronic system, particularly when operating at higher voltage levels. An example of such a supervisor is the S-80819CNPF-B8ETFG.

The S-80819CNPF-B8ETFG is a voltage supervisor IC which offers comprehensive overvoltage protection, as well as monitoring and detection, for PC motherboard, notebook and other digital and/or analogue equipment which are powered by 1.2V to 3.63V. It consists of adjustable voltage input sensing and overcurrent protection circuit and can be configured in a variety of operating modes.

Application Field

The S-80819CNPF-B8ETFG is primarily used in telecommunications, industrial automation and power engineering applications. It is suitable for motherboards, notebooks, and personal computers, where high-efficiency power regulation is required. The flexibility of configuration, combined with small size and low power consumption, make it suitable for most cost- conscious engineers.

Working Principle

The S-80819CNPF-B8ETFG works by monitoring voltage and current levels for a system and controlling power regulation. The device can be configured to operate in different operating modes. This includes monitoring operating conditions and providing warning signals or controlling the power system when unsafe conditions are detected. When the voltage level enters an overvoltage condition, the device is triggered, resulting in an interrupt signal or reset.

The IC supports several voltage and current monitoring thresholds that can be adjusted depending on the application. One adjustable trigger level is the Event Latched Enable (ELE), which is the input sensing voltage. This threshold can be adjusted with an external resistor to provide protection against an overvoltage condition. In addition, overcurrent monitoring is possible by adding a current sense resistor onto the circuit. This provides protection against overcurrent events by setting the maximum operating current.

The S-80819CNPF-B8ETFG provides a comprehensive voltage and current monitoring solution that minimizes system downtime and eliminates unnecessary power-related losses. It is equipped with adjustable threshold levels and can operate in a variety of operating modes. This makes it suitable for many cost-conscious applications, especially in electronics, telecommunications and power engineering.
