The S-80820CNPF-B8FTFU is a PMIC, or power management integrated circuit, specifically classified as a supervisor. Supervisors fall under the general umbrella of PMICs which are used to manage and control power delivered to various parts of a device, for reliable and consistent performance. Supervisors specifically are used on circuit boards to provide protection against voltage irregularities and to generate reset signals when the circuit exceeds correct operating conditions. This particular model superficially appears to be used mostly in automotive applications, however, with a bit of research, its use in other applications can be determined. This model has the features necessary to make it applicable to a range of general application fields.

The S-80820CNPF-B8FTFU is manufactured by Sanken, a Japanese electronics firm. It is an 8-pin IC for use with 3.3V or 5V circuits and offers a highly compact design to save board space. It does not require an external capacitor, which simplifies circuit layout and lowers component costs. The device offers about 500 μA of current draw, making it an attractive option for small, low-power applications.

The main function of a supervisor is to monitor the voltage supplied to the circuit, and to generate a reset signal if the supply voltage drops too low. This model provides overvoltage, undervoltage, current protection and reset output. The low detection threshold of 2.5V and the reset output of 1.1V are both adjustable by using external resistors or capacitors, allowing the device to be customized to different applications.

The S-80820CNPF-B8FTFU is suitable for a range of applications Including personal computers, games and portable electronic devices. It is also used in automotive applications such as engine and transmission control, computers, radios and monitors, and video systems. As a supervisor, it serves to protect against surges in voltage and short circuits, thereby increasing the reliability of a device and preventing damage from occurring. Additionally, it can provide a reset signal to reset the processor or other circuits after a power failure.

The S-80820CNPF-B8FTFU is relatively easy to use, with a few components required for the circuit. The IC should be connected to the power supply, with the overvoltage, undervoltage, ground, and reset outputs connected to their respective lines. The voltage levels and reset signal can be adjusted using external resistors or capacitors. With minimal circuit adjustments, the device can be optimized for specific applications.

The S-80820CNPF-B8FTFU is a versatile and compact supervisor IC that is suitable for a range of general applications. It provides reliable overvoltage, undervoltage, and current protection, as well as a reset signal when necessary. The device has a low current draw and requires few external components, making it an attractive option for small circuit designs. With its easy setup and minimal board space, the S-80820CNPF-B8FTFU is an ideal option for a number of different applications.
