Introduction

PMIC - Supervisors are widely used today in many electronic devices. The S-80840CLNB-B6ZT2G is a high performance supervisor that is used in a broad range of applications and provides a range of robust features. This article will examine the application field and working principle of the S-80840CLNB-B6ZT2G in detail.

Application Field

The S-80840CLNB-B6ZT2G supervisor is ideally suited for modern low-power, high-reliability applications. It is designed to be used in high-efficiency power-supply and device-level power management. The supervisor is suitable for power supplies of 10V to 25V, and its operating temperature range is −40°C to +85°C.The supervisor integrates all the necessary features that are necessary for power management, such as under-voltage/over-voltage monitoring, power-fail, power-good and from-good detection, short-circuit, and low-battery detection. These features make it suitable for a wide range of applications, from computer motherboards to telecom switching systems and industrial controllers.

Working Principle

The S-80840CLNB-B6ZT2G supervisor operates on the same principles as other PMIC Supervisors. It monitors the input voltage, current, and temperature and sends a flag to the microcontroller when certain conditions are met.When the input voltage reaches either its upper or lower limit, the supervisor sends a power-fail/power-good signal to the microcontroller. This signal can be used to disable and reset the system, or to switch to a backup power source.The supervisor also monitors the temperature, and can send a temperature-fault signal to the microcontroller if the temperature exceeds a certain threshold. If this signal is received, the microcontroller can shut down the system or take other necessary corrective measures.The supervisor also monitors the battery voltage and sends a low-battery signal to the microcontroller when the battery voltage drops below the threshold. This is useful in preventing system malfunctions and ensuring long battery life.

Conclusion

The S-80840CLNB-B6ZT2G is a high-performance, low-power supervisor that is suitable for a wide range of applications. It provides a range of robust features, including under-voltage/over-voltage monitoring, power-fail, power-good and from-good detection, short-circuit and low-battery detection. By monitoring the input voltage, current, and temperature, the S-80840CLNB-B6ZT2G can help to ensure reliable operation of electronic systems, and provide long battery life.
