The S-80859CNNB-B9KT2G is a supervisor integrated circuit from Toshiba Semiconductor, which offers the highest level of accuracy when it comes to system reset and monitoring. This device is classified as a Programmable Microcontroller Interface Chip (PMIC) - Supervisors, meaning it offers various functions to be used in different types of applications.

The S-80859CNNB-B9KT2G is capable of monitoring system power and resetting when necessary to prevent system damage. The PMIC is also equipped with an adjustable reset window timer enabling different power-off and power-on levels. The onboard 8-bit timer is highly accurate, making it the ideal choice for industrial and commercial applications.

In terms of applications, the S-80859 CNNB-B9KT2G can be used in a range of different applications including power supplies, computers, and embedded systems. It can also be used for monitoring temperature, voltage and current levels. Due to its ability to detect power-off and power-on levels, the PMIC can be used to prevent system lock-ups and malfunctions, and help improve system reliability.

The working principle behind the S-80859CNNB-B9KT2G is fairly simple. The PMIC includes two independent power suppliers; one powers the reset circuit and the other powers the onboard performance monitors (OPMs). When the power off level is reached, the PMIC will immediately seize and hold the reset line low to the correct logic level. When the power on level is reached, the reset line will be driven high, bringing the system back to its normal operating state.

This resetting process is then repeated on a regular basis, ensuring that the system remains stable and secure. If the system is not able to detect the proper power-off or power-on levels, it will shut down and reset itself, keeping the system from suffering any potential damage.

In conclusion, the S-80859CNNB-B9KT2G is a highly reliable PMIC with a wide range of application fields and the ability to rapidly detect and reset system power. Its programmable reset window timer and 8-bit onboard timer offers the highest level of accuracy, enabling it to be used in a variety of industrial, commercial and embedded applications.
