S-80843CNUA-B84T2U Integrated Circuits (ICs)

The S-80843CNUA-B84T2U (also known as the CXNU) is an advanced Power Management Integrated Circuit (PMIC) supervisor for low voltage, integrated application processors and analog circuits. It is part of a larger family of similar PMICs, specifically Supervisors.

The CXNU is specifically designed to provide efficient power control and management for low-voltage integrated circuits. It features an integrated power management system and with the addition of external components, it is capable of advanced power gating, including dynamic voltage scaling (DVS), diode emulation, and voltage frequency scaling (VFS).

The CXNU’s Supervisory part is comprised of four major modules: a voltage regulator, an overvoltage and undervoltage detector, an automatic voltage scaling (AVS) module, and an external power relay circuit. The integrated voltage regulator ensures a stable and accurately regulated voltage supply at its output. The overvoltage and undervoltage detector immediately shuts down the system in response to dangerous voltage levels. The AVS module provides intelligent power gating based on the actual voltage values of the system. Finally, the external power relay circuit allows an external power shutdown when the pre-defined voltage levels are reached.

The CXNU is specifically intended for use in power-sensitive applications such as embedded systems, automotive electronics, industrial controls and consumer electronics. It is based on a simple yet robust design and is suitable for many low voltage applications. Its features include low power consumption, high accuracy, low noise, and high reliability.

In summary, the S-80843CNUA-B84T2U is an advanced PMIC supervisor for low voltage, integrated application processors and analog circuits. Its features make it suitable for many low voltage applications and its reliability ensures consistent power control and management.
