S-80941CNPF-G9BTFU

Introduction

The S-80941CNPF-G9BTFU, belonging to the PMIC - Supervisors category, is a voltage supervisor IC specifically designed to monitor power supply voltage in system circuits, keep track of its status, and notify when it varies beyond the predetermined safe range.

Application Field

The S-80941CNPF-G9BTFU supports an operating voltage range of 2.057V to 5.5V. It is used in systems where short drop or break occurs in the system, such as automotive systems and industrial control systems. When the voltage is higher than the specified upper limit, the power supply is cut off, and when the voltage is lower than the specified lower limit, the power supply restarts and rises. At the same time, reset signals can be output when power supply voltage is abnormally high or low.

Working Principle

The S-80941CNPF-G9BTFU, when powered on, assesses the system\'s power supply voltage at designated time intervals. When there is a significant voltage drop or break exceeding the predetermined safe range, the chip triggers a reset, restoring and balancing the voltage supply. It is designed to recognise low as well as higher voltages, and works as an interface between the system and its own power supply.

Additionally, the S-80941CNPF-G9BTFU supports reset signals output in either active low or active high formats. It can also be combined with the delayed reset timer function to provide signals delayed by fixed intervals or customized based on user settings. It also supports manual reset and wiring reset inputs, as well as power indicators and detection signals. Moreover, built-in WTD (watchdog timer) helps prevent system crashes and halt.

Package

The S-80941CNPF-G9BTFU supervisor IC comes in surface-mount packages, with pin pitch of .5mm and size of 2.0 x 2.9mm.

Conclusion

The S-80941CNPF-G9BTFU belongs to the PMIC - Supervisor category. It is specifically designed to monitor power supply voltage in system circuits, keep track of its status and notify when it varies beyond the predetermined safe range. It supports reset signals output in active low or active high formats and has a built-in WTD (watchdog timer) to prevent system crashes and halt. At the same time, it comes in a compact package, with pin pitch of 0.5mm and size of 2.0 x 2.9mm.
