Introduction

The S-80934CNPF-G84TFG is a power management IC (PMIC) specifically designated as a supervisor. It is used in any system requiring monitoring of under-voltage, over-voltage, and over-temperature events. The device includes two low supply voltage supervisors (UVLO1, UVLO2) and a temperature supervisor (TSD) to provide protection of the system power supply. The S-80934CNPF-G84TFG is a precision device that provides a supervisory power supply to prevent voltage and temperature issues.

Application Field

The S-80934CNPF-G84TFG is commonly used in many applications. The device has been designed for use in computer servers, automobiles, digital cameras, automation systems, robots and various electronic products which require monitoring of under-voltage, over-voltage, and over-temperature. The device can be used to protect computer systems and components from power supply problems such as brown-outs, over-voltage, over-current, and overheating. The device is also used in automotive applications to protect systems from severe voltage conditions.

Working Principle

The S-80934CNPF-G84TFG is a supervisor device providing three protection functions within a single integrated circuit (IC). The device is able to detect and monitor under-voltage, over-voltage, and over-temperature conditions. The device is designed to be used in an open-loop configuration. The S-80934CNPF-G84TFG has an internal power supply monitor that provides protection from under-voltage, over-voltage, and over-temperature conditions.The device\'s internal supervisor comprises two low supply voltage supervisors (UVLO1, UVLO2) and a temperature supervisor (TSD). The two UVLO1 and UVLO2 supervisors monitor the system power supply input voltage, and can be configured to trigger a logic-low active signal in the event of an under-voltage or over-voltage condition. The temperature supervisor monitors the temperature within the device, and can be configured to trigger a logic-low active signal in the event of an over-temperature condition. The device can also trigger an alarm signal in under-voltage, over-voltage, or over-temperature conditions.

Conclusion

The S-80934CNPF-G84TFG is a power management IC used as a supervisor device to monitor under-voltage, over-voltage, and over-temperature conditions. The device is designed for use in electronic products, such as computer systems, automobiles, digital cameras, automation systems, and robots, where protection from severe voltage and/or temperature events is needed. The IC provides three protection functions within a single IC, including two low supply voltage supervisors (UVLO1, UVLO2) and a temperature supervisor (TSD). The device is easily configured and can be used in an open-loop configuration.
