Power Management ICs (PMICs), commonly referred to as Supervisors, are integrated circuit devices designed to provide regulated power supply and management capabilities for microprocessors, microcontrollers, and other digital systems. The S-80947CNPF-G9HTFG PMIC supervisor is one of the most popular with large scale integrated circuit manufacturers, providing protection and management capabilities for advanced and cost-sensitive applications. This article will discuss the application field and working principle of the S-80947CNPF-G9HTFG PMIC supervisor.

The S-80947CNPF-G9HTFG PMIC supervisor is a small integrated circuit that is used to provide regulated supply and management. This supervisor is powered by 2.5V Vddin source, and supports initial and main supply options with a sensing mechanism for VDDIN and VDDOUT. It includes integrated sequencing for sequencing Vddin, Vddout, and POR detect signals. The supervisor provides a protection circuit by monitoring the input supply for various power conditions, such as overvoltage, undervoltage, and brownout conditions. Additionally, it can be used to detect out-of-tolerance conditions on other power supply lines. The supervisor provides Enhanced Precision Reset, which allows better control over the reset process by increasing the accuracy of both the bandgap voltage reference and the reset voltage detection. Other features of the S-80947CNPF-G9HTFG PMIC supervisor include: adjustable power-on reset delay, adjustable precision reset delay, programmable reset reset level, programmable watchdog timer, on-chip voltage regulator, output voltage and current monitoring, and power fail detection.

The S-80947CNPF-G9HTFG PMIC supervisor’s application field is extensive. The supervisor is suitable for microcontrollers, such as the ARM Cortex A5 and M3. It can be used in embedded systems, computer systems, and small-scale devices requiring consistent power management and protection. It is also a suitable choice for power solutions for mobile devices and can be used in a variety of applications, such as automotive, consumer electronics, and healthcare. Moreover, the supervisor can be used for a wide range of consumer, industrial, and medical products.

When it comes to working principle, the S-80947CNPF-G9HTFG PMIC supervisor provides all the necessary power management features and protections in one small package. After the input voltage is applied to the supervisor, it begins the sequencing process. First, the output voltage is monitored and compared to the Vpdref reference voltage. The supervisor then compares the monitored output voltage to the Vref reference voltage. The supervisor then initiates the reset process by asserting the reset signal upon recognition of a Vref low condition. After the reset process has been completed, the supervisor begins to monitor both the input supply and the output voltages in order to detect out-of-tolerance conditions. The supervisor also provides other power fail detection features, such as offset detection, low power mode support, and over-temperature protection. Additionally, the supervisor includes a watchdog timer for monitoring various time-out conditions.

The S-80947CNPF-G9HTFG PMIC supervisor provides the ultimate in power management and protection for microcontrollers, embedded systems, and other small-scale devices. It is well-suited for a wide range of applications and provides all necessary power management features in one small package. Its protection circuits monitor the input supply for various power conditions and provide Enhanced Precision Reset for better control over the reset process. The supervisor also includes a watchdog timer for monitoring of time-out conditions. The S-80947CNPF-G9HTFG PMIC is a powerful and reliable power management solution for many modern applications.
