Introduction

PMIC - Supervisors are a type of advanced power management integrated circuit (PMIC) that is designed to help protect sensitive electronic systems from shock, vibration, and other types of environmental stress. S-80930CNPF-G80TFG is one such supervisor IC, whose application field and working principle will be discussed in this article.

Application Fields

S-80930CNPF-G80TFG is a 8-pin SOP Supervisory IC that is suitable for a variety of high-end embedded systems, such as servers and networking equipment. It is designed to help protect against over-voltage, under-voltage, and over-temperature events, providing accurate system reset and power-on protection. This supervisor IC can be used in a variety of applications such as Medical, Automotive, Industrial, Military, and Avionics systems.

Working Principle

S-80930CNPF-G80TFG is designed to help maintain system stability and reliability by rigorously monitoring multiple voltage levels and power supply parameters. The supervisor IC uses an internal voltage reference and bandgap detector to compare the system’s input and output voltages. The IC will then react to any discrepancies between the actual and monitored voltages by producing a reset signal or switching off the power supply. It can also be programmed to trigger an alert signal in the event of an over-temperature situation. To further protect the system from voltage surge, S-80930CNPF-G80TFG is equipped with an adjustable over-voltage detector. This is used to detect and shut down the power supply in the event of a power spike. The supervisor IC also supports a variety of advanced features such as programmable watchdog timers, adjustable pre-settable threshold values, and thermal protection.

Conclusion

S-80930CNPF-G80TFG is an advanced supervisor IC designed to provide comprehensive power protection for high-end embedded systems. It monitors multiple voltage levels and power supply parameters to ensure system stability and reliability, and is equipped with several advanced features such as programmable watchdog timers and adjustable pre-settable threshold values. This supervisor IC is suitable for a variety of applications, such as Medical, Automotive, Industrial, Military, and Avionics systems.
