The XC6121E627MR-G is a state-of-the-art supervisory integrated circuit designed to provide a comprehensive and reliable protection and monitoring function required on portable and embedded micro-computer systems. The device features hardware and software protection systems, low voltage detection, and a wide range of reset functions. It was also designed to be highly compatible and fully integrated with numerous microcontroller platforms, including 8/16/32-bit processors. This article provides an overview of the XC6121E627MR-G application field and its working principle.

Application Fields

The XC6121E627MR-G is ideal for the safety and reliability requirements of applications such as medical equipment, automotive systems, tablet and notebook PCs, hard disk drives, industrial controllers, and various other portable and embedded systems. It is packaged in a thermally enhanced DFN24-6 package with a low profile of 1.0mm, allowing designers to reduce the size of their system while still taking advantage of all the features of the XC6121. In addition, the XC6121 is designed to ensure reliable operation in extreme temperatures, ranging from –40°C to +85°C.

The XC6121E627MR-G is also designed with a wide range of reset functions, including power-on reset (POR) and system reset (RST) functions, as well as protected reset monitoring and temperature-compensated reset. It also has a voltage detection circuit to detect critical system conditions before the circuit malfunctions. This feature is especially useful for critical system conditions, such as low power or supply voltage issues, that can cause system instability or failure. The XC6121 also includes software-programmable settings for both the reset threshold and the time period between detection and reset. With the various settings of the XC6121, designers have the flexibility to customize their system reset scheme in order to maximize system reliability.

Working Principle

The XC6121E627MR-G applies a continuous monitoring signal to the input supply voltage and the internal core voltage of the system. The detection signal voltage can be independently programmed and is compared with two programmable threshold values. When the signal voltage falls below either of the two threshold values, the XC6121E627MR-G will send out either a reset output or an interrupt signal, depending on the settings.

The XC6121E627MR-G also provides an additional detection signal to detect over-temperature conditions. The temperature detection circuit uses an internal or external temperature sensor (NTC) to detect the temperature of the system. An interrupt signal will be sent out if the temperature exceeds the specified threshold. This feature is used to protect the device and the system from conditions that could cause damage due to excessive heat.

The XC6121E627MR-G also features a low voltage detection function. This function monitors the system voltage and sends out an interrupt signal when the voltage falls below a specified threshold. This feature is especially useful when the system is operating on a low voltage supply as it ensures a safe shut-down in order to prevent any damage that could occur due to low voltage operation. In addition to these reset and protection functions, the XC6121E627MR-G also includes a built-in watchdog timer for system reliability.

The XC6121E627MR-G is a highly reliable and versatile supervisor integrated circuit designed to support a wide variety of applications. It offers a wide range of reset functions and software programming abilities, as well as a built-in temperature and voltage detection system for additional safety and reliability. With its small size, low power consumption and high level of integration, the XC6121E627MR-G is an ideal solution for a wide range of applications.
