The S-80844CNNB-B85T2G is a Supervisors-type PMIC (Power Management Integrated Circuits) from Nihon Inter Electronics Corporation, designed to monitor power systems for devices such as mobile phones, clock generators, and DSPs.

This device has a wide range of applications; it offers its users stable power output and a precise and fast response to any over/under voltage events. It can be used to protect against shorts as well as over voltage and over temperature events. It also offers two modes of reset logic, one active low and one active high, to allow for various applications in power systems.

In addition, the S-80844CNNB-B85T2G can also be used to detect fast power-on surges and detect low-battery ranges, such as when a device is running low on power. This feature is especially useful for battery-dependent systems, such as mobile devices, where a low battery might cause the device to shut down prematurely.

The S-80844CNNB-B85T2G also offers a high degree of reliability, with a high repeatability of trip points (±3%), as well as adjustable, user-programmable delays to avoid false tripping due to short-term power events. This is essential for reliable power systems, where accuracy and timing are of paramount importance.

The primary advantage of the S-80844CNNB-B85T2G is that it is programmable, allowing users to set their own voltage and temperature trip point andDelay settings. The programming is done via PMBus or I2C-compatible interfaces. Additionally, this device offers several protection algorithms, such as a low-battery monitor, a power-on surge monitor, and an over-temperature monitor.

The working principle of the S-80844CNNB-B85T2G is fairly straightforward. It has a comparator block which continuously monitors the power supply and compares it to the set trip point. If a certain event occurs, it will trigger a protection cycle. During the protection cycle, an output signal is sent to a transistor which will turn off the input or output device, or both. In addition, an internal timer is used to ensure that the protection cycle does not occur too often.

In conclusion, the S-80844CNNB-B85T2G is a powerful and reliable Supervisors-type PMIC from Nihon Inter Electronics Corporation. It offers a wide range of applications in power systems, including protection against shorts, over voltage, and over-temperature events. It also boasts precise and fast response to any over/under voltage events and adjustable delay settings. Finally, it allows users to program the device via PMBus or I2C-compatible interfaces, allowing them to tailor it to their specific needs.
