Power Management Integrated Circuit (PMIC) is a relatively new integrated circuit, derived from Power and Energy Management Systems (PEMS). It is a combination of several functions, or "blocks", that are used in a wide number of applications, such as consumer electronics, mobile and desktop computing, automotive, industrial, aerospace and defense. At the heart of PMIC technology is the supervisor or controller, which provides the intelligence needed to manage and regulate the power and energy used by the system or application. The S-80955CNPF-G9RTFG supervisor is a modern example of such technology, providing important features and functions to support the latest applications.

The S-80955CNPF-G9RTFG supervisor is an advanced PMIC that features an integrated voltage supervisor and digital programmable logic (CPLD) for voltage monitoring, voltage supervision, initialization and reset supervision. It also features a power management block for read/write operations, and a serial bus interface for communication with external components. This IC package is designed to meet the most demanding applications, from desktops and notebooks to automotive and industrial systems, while offering robust protection, high performance, and industry-leading ease of integration.

The voltage supervisor in the S-80955CNPF-G9RTFG is responsible for monitoring the power line voltages, such as main power supplies, auxiliary power supplies, and other supply levels as needed. The supervisor is able to detect and alert the system of an over or under voltage condition. The supervisor is also able to detect and alert the system of brownouts, or slow changes in voltage that can cause system instability. In addition, the supervisor has an adjustable threshold, allowing the system to select the appropriate voltage thresholds for optimal protection.

The programmable logic (CPLD) in the S-80955CNPF-G9RTFG provides more functionality for customizing the supervisor’s features for specific applications. The CPLD can be used to control the initialization sequence by setting the voltage levels and output type, program the watchdog timer, reset the supervisor for a power up sequence, control the sequence of activities during a power down sequence, and receive and execute commands from the bus interface. The CPLD can also be configured to generate a reset signal when input thresholds are exceeded or a condition is otherwise detected by the supervisor.

In addition to voltage supervision and initialization, the S-80955CNPF-G9RTFG includes a power management block for managing the power supply levels and their related read/write operations. This includes the ability to select, monitor, control, and adjust the various power rails within a system or application. The power management block also handles the output power sequencing and operation, as well as write protection and fault detection.

Finally, the serial bus interface provides communications between the supervisor and other system components. This interface allows the supervisor to transfer data to, and receive data from, any device on the bus. The data can include commands, status information, and configuration information, which all contribute to the supervisor’s ability to optimize the operation of the system.

In conclusion, S-80955CNPF-G9RTFG is an advanced PMIC board designed to meet the most demanding applications. It features a voltage supervisor, programmable logic, and a power management block, as well as a serial bus interface for communication between the IC and external components. Together, these features provide the advanced intelligence needed to manage and regulate the power and energy used by a system or application in order to optimize its performance.
