PMIC (Power Management Integrated Circuit) Supervisors are an essential aspect of high-end power management electronics and industrial automation systems. They are designed to monitor power and voltage signals and to switch between power sources when necessary. XC6121F542ER-G is a supervisor from NXP Semiconductors that monitors, supervises and switches different power sources. In this article, we discuss the application field and working principle of the XC6121F542ER-G.

Applications of the XC6121F542ER-G

The XC6121F542ER-G has a wide range of applications in industrial and commercial products including FPGA, ASIC, motor control and motion control applications. It is used to monitor power supplies in industrial and commercial applications, IT applications, handheld devices, servers and notebooks, security systems, and other applications where high-end power management and control are needed. Additionally, it is also used for applications that require efficient power management, such as LED drivers, smart meters, and so on.

The XC6121F542ER-G is also used in systems that require multiple power sources, such as microprocessor-based systems, digital signal processing (DSP) systems, distributed systems, and so on. It is used to monitor, supervise and switch between different power sources as needed to maintain system stability and functionality.

Working Principle of XC6121F542ER-G Supervisor

The XC6121F542ER-G is designed to monitor and supervise multiple supplies. It uses a multi-level supervisor architecture with input voltage levels that range from 3.1 volts to 5.5 volts. It features a wide operating temperature range of -20°C to +85°C, which provides system designers with a reliable option for high-end power management. It features a low voltage detect (LVD) threshold that is adjustable from 1.5 volts to 4.67 volts, and a low power threshold (LPT) threshold that is adjustable from 0.06 volts to 0.8 volts.

The XC6121F542ER-G also has an active current drain that is adjustable from 10 μA to 320 μA depending on the supply voltage. It also features a push-button reset function that can be triggered manually or remotely. The push-button reset function will reset the system if the active current drain is lower than the adjustable limit. It also features an over temperature warning via the reset line.

In order to monitor, supervise and switch the power supplies, the XC6121F542ER-G supervisor utilizes a multilevel voltage detection architecture. The power supervisor monitors the power supply voltages at the input and output pins and switches between supplies depending on the input voltage level. The supervisor can detect the input voltage of the main power supply as well as the voltage of a backup power supply. If the main supply voltage drops below a certain threshold, the supervisor will switch to the backup power supply. The supervisor also has an adjustable turn-on delay and an adjustable turn-off delay to enable a smooth transition between supplies.

The XC6121F542ER-G is an ideal solution for applications requiring high-end power management, reliability and safety. It offers a wide range of features and functions and is suitable for a wide range of applications. It is designed to monitor, supervise and switch between power supplies effortlessly and reliably, as well as provide reliable temperature protection.
