Working Principle

The S-80945CNPF-G9FTFG is designed to provide reliable circuit protection. It uses a voltage-controlled voltage source (VCVS) to accurately measure the input supply voltage and produces an output signal when the voltage drops to a certain level. It also monitors the temperature of the environment, and when the temperature exceeds a certain threshold, it will produce an alarm signal. The S-80945CNPF-G9FTFG also has a low-voltage reset (LVR) which can reset the power supply when the voltage drops below a certain low level.

The S-80945CNPF-G9FTFG also features an auto-shutdown function that will automatically shut down the power supply in case of overvoltage. This helps to protect the circuit from damage due to overvoltage. It also provides a reset signal that can be used to reset the power supply after an overvoltage event.

In addition to the voltage and temperature protection, the S-80945CNPF-G9FTFG also provides a watchdog timer function. This function keeps track of the state of the system and triggers a reset if the system does not respond within a certain time limit. This helps to protect the circuit from a system malfunction.

The S-80945CNPF-G9FTFG also features an adjustable voltage output that can be used to supply a constant voltage to the circuit. This is useful for providing a regulated power supply to the system. The S-80945CNPF-G9FTFG can also be used as an emergency power supply in case of a power outage.

Overall, the S-80945CNPF-G9FTFG is a reliable and efficient PMIC supervisor, providing a wide range of features and protection. Its versatile nature makes it suitable for a variety of applications, making it an ideal choice for circuit protection and management.
