The S-80852CNUA-B9DT2U is categorized as a PMIC (Power Management Integrated Circuit) supervisor. The application field of the IC and its working principle are explained in this article.

The S-80852CNUA-B9DT2U is a voltage supervisor IC with two buffered reset outputs. It is designed to monitor system voltages in a range of microprocessor-based systems and provides Input voltage monitoring and reset output functions. The device includes an integrated voltage reference for high accuracy voltage monitoring, a MOSFET to supply current for the reset output, and an active-low manual reset input.

The S-80852CNUA-B9DT2U can be used in various applications such as automotive, industrial, and general embedded systems. It is useful for applications where low power consumption and reliable power management are important. The device is also highly integrated with its well-defined reset threshold and integrated voltage reference, thus enabling a simple and compact design.

Now let’s look at how this device works. The S-80852CNUA-B9DT2U has two voltage threshold comparators with an integrated voltage reference typically used to monitor different supply voltages. It has two buffered CMOS logic outputs that drive reset signals to the system when the monitored supply voltage falls below the user-defined threshold. The device also has an active low manual reset input that can be used to manually reset the system. When the reset conditions occur, the IC will drive its reset outputs low, resulting in a reset signal applied to the system electronics.

Another important feature of the S-80852CNUA-B9DT2U is its power-saving hysteresis transitions. Hysteresis transitions are necessary to minimize the power consumption of the IC and to prevent spurious reset signals from being generated. The hysteresis means that the reset conditions will only be asserted when the monitored voltage falls below the user-defined threshold and remain asserted until the monitored voltage rises above the other user-defined threshold. This mechanism ensures that the voltage fluctuations in the system will not generate spurious reset signals and also reduce the power consumption of the IC.

In addition to the voltage monitoring, the S-80852CNUA-B9DT2U also has an active-low manual reset input. This can be used to manually reset the system, if necessary. The reset output will be driven high when the manual reset input is active low and the system conditions reach the user-defined reset thresholds.

The S-80852CNUA-B9DT2U is a versatile PMIC supervisor IC. Its integrated voltage reference, buffered reset outputs, and low power consumption make it an ideal choice for embedded systems where reliable power management is important. It is available in a small and compact package, making it an easy choice for compact designs.

In summary, the S-80852CNUA-B9DT2U is a voltage supervisor IC with two buffered reset outputs, designed to monitor system voltages in a range of microprocessor-based systems. It has an integrated voltage reference for high accuracy voltage monitoring and a MOSFET to supply current for the reset output. The device also has an active-low manual reset input. The low power consumption and hysteresis transitions make this IC an ideal choice for embedded systems where reliable power management is a priority.
