PMIC, also known as Power Management Integrated Circuit, is a device used to regulate the power supply for electronic circuits. In PMIC, supervisors are an important device for protecting circuits from power failures, momentary outages, and other fault conditions. A typical supervisor IC, such as S-80953CNNB-G9PT2G, is capable of monitoring power supply voltages and signalling the application when a fault is detected. In this article, we will discuss the application fields and working principle of S-80953CNNB-G9PT2G.

Application fields: S-80953CNNB-G9PT2G is used in a wide variety of power supply systems, such as computers, communication systems, data processing systems, etc. This IC can be used both as a one-shot supervisor or as a watchdog timer to continuously monitor voltages for fault conditions. In addition, the S-80953CNNB-G9PT2G is designed for use in low-power consumption systems, making it an ideal choice for portable devices and embedded systems.

Working Principle: The S-80953CNNB-G9PT2G has both an input voltage sense pin and an output voltage stabilization pin. When the supply voltage is below a predetermined threshold, the supervisor will indicate a fault condition. The supervisor can be programmed to output a reset signal, an interrupt signal, or both when the fault is detected. The supervisor also includes an adjustable delay feature, allowing the system time to respond before a fault indicator is issued. The delay time can be programmed to suit the particular application. In addition, the supervisor also has a power-on reset circuit, which enables the supervisor to detect power supply faults even when the application is powered on.

S-80953CNNB-G9PT2G is a highly versatile and reliable supervisor for power supply related applications. Its design offers superior performance in diagnosing and protecting systems from power supply faults. The supervisor is capable of monitoring both input voltages and output voltages, and can be programmed to delay the fault indication, giving the system time to respond before fault detection. It also includes a power-on reset circuit, enabling the supervisor to detect power supply faults even when the system is powered on. The S-80953CNNB-G9PT2G is an ideal choice for a wide variety of applications, making it one of the most popular PMIC supervisors available.
