Power management integrated circuits (PMICs) are electronic devices which manage the power requirements of electronic hardware devices. PMICs can provide power regulation, fault protection, transient voltage protection, load cells, and many other power management functions. The S-80924CNMC-G8UT2U is an advanced PMIC supervisory device designed to monitor critical power supply parameters to ensure system safety. It plays an important role in providing reliable power supply management to ensure system efficiency and stability.

The S-80924CNMC-G8UT2U PMIC is an integrated system-on-chip circuit that combines multiple voltage level detection, adjustable delay time, 5A output current capability, power-on reset (POR) functionality, and other features in a small package. Its main function is to monitor critical power supply voltages, initiate reset action when they cross the safe range and delay system reset accordingly. The device has two channels – main channel (Ch1) and auxiliary channel (Ch2). The main channel monitors voltage levels for the digital and analog parts of the system respectively. The auxiliary channel is provided for monitoring any other system voltage which includes LDO, battery, real-time clock, and so on. Both channels are configured for dual detection with 4 voltage thresholds for Ch1 and 3 voltage thresholds for Ch2 to provide maximum flexibility for the application.

The operation of the S-80924CNMC-G8UT2U is quite simple. When the voltage at the monitored terminals exceeds the preset thresholds, the device will initiate a reset signal and delay its action based on the user-provided delay time. This delayed reset signal is then used to start the system reset process. The provided delay time can be adjusted using the external capacitor connected to the device. The device also features a low voltage monitoring (LVD) mode, which monitors both the main and auxiliary channels and sends a reset signal when the monitored voltage drops below the preset level.

The S-80924CNMC-G8UT2U is suitable for a wide range of application such as MCUs, DSPs, FPGAs, embedded systems, LCD displays and other embedded applications. Its fast and reliable reset capability, flexibility, and compact size makes it ideal for use in devices where space is a constraint. This device also satisfies the requirements for UL and CE approvals because of its capability to monitor and react in accordance with the preset voltage levels.

In conclusion, the S-80924CNMC-G8UT2U is a powerful PMIC supervisory device with multiple voltage level detection, adjustable delay time, 5A output current capability, power-on reset (POR) functionality, and other features in a small package. It is suitable for use in both MCUs, DSPs, FPGAs, embedded systems, LCD displays, and other embedded applications due to its fast reset capability and compact size. Its features satisfy the requirements for UL and CE approvals, making it an ideal choice for power supply management and reliable performance.
