Supervisors are types of Power Management Integrated Circuits (PMICs) that protect embedded microcontrollers from power glitches and faults. The S-80954CNMC-G9QT2U supervisor is a low-power, low-cost, precision voltage monitoring and voltage supervising device from STMicroelectronic. It provides a threshold voltage of 2.38V to 3.6V. It has power-on reset (POR) and power-off reset (PFR) operations, as well as an independent circuit monitoring function. It also features adjustable watchdog timeout and an integrated system power-on reset delay.

The S-80954CNMC-G9QT2U supervisor is designed to monitor and reset a downstream system in the event of a fault such as an overvoltage, undervoltage, rapid switch-off, or short-circuit. It also monitors the supply voltage through an internal comparator and provides reset signals in case of supply voltage faults. This is done by adjusting the threshold voltage level and other settings. If the monitoring voltage is outside of the range specified, the reset signal is activated. Additionally, the device can be used to supervise the system’s power-on functions and reset the processor in case of system problems.

The S-80954CNMC-G9QT2U supervisor is suitable for various bypass applications such as microcontroller, DSP, ASIC, or FPGA applications. It can also be used in automotive applications, IoT application platforms, and industrial PC applications. Its 2.38V to 3.6V adjustable voltage monitoring range and its ±2% accuracy allow it to cover a wide range of voltage ranges for different application fields. Its high accuracy and low power consumption make it an ideal supervisor for many of today\'s applications.

The S-80954CNMC-G9QT2U supervisor can be used to monitor and protect downstream systems against overvoltages, undervoltages, and rapid switch-off events. It is designed to reset the microcontroller, ASIC, or FPGA in case of a voltage fault, protecting these devices from damage. The device also has an adjustable watchdog timeout and a power-on reset delay, allowing it to act as a supervisor for multiple devices. Furthermore, its wide voltage range and high accuracy make it suitable for a variety of applications, ranging from automotive to industrial.

Overall, the S-80954CNMC-G9QT2U supervisor is a reliable and cost-effective supervisor for microcontrollers, ASICs, and FPGAs. It monitors the voltage of a downstream system with high accuracy and protects the system from power glitches and faults. Additionally, it is suitable for a wide range of applications such as automotive, IoT, and industrial PCs. The adjustable voltage levels and watchdog timeout allow the device to act as a supervisor for multiple devices, making it an ideal choice for embedded system protection.
