The XC6121A421MR-G Supervisors is a Japanese original Integrated Circuits (ICs) developed by Toshiba, belongs to its “Semiconductor” product line. This IC is a part of the XC6121A programmable family, coming with mainly adjustable functional blocks like as supply voltage supervisors, oscillators, watchdogs, reset outputs, voltage monitors, thermal protection, and GPIOs. By employing this micro IC, designer or engineer can realizing monitoring the system voltage or temperature levels and various of reset protection functions for various of electronic systems. In short, XC6121A421MR-G supervisors is an ideal solution for the most systems designers.

XC6121A421MR-G supervisors consists of a variety of components, and are designed to align with particular applications. The core part is made of a voltage monitoring circuit, a delay circuit, and a power-on reset circuit. On the other side, this micro IC features with integrated oscillator and GPIO to control system applications easily. Its PVIN pin is the supply voltage input which connects the system main power, and the LVD pin is used to adjust the voltage down threshold value. Above the threshold value, the reset output BL will work regardless of the delay circuit function. Once the BL is off, it indicates the system is powered on normally while when BL is on, it means the system voltage outage, system will be reset then.

XC6121A421MR-G micro IC has a strong capability and broad application ranges, it can be used for various electronic products and systems. And, it belongs to PMIC – supervisors. Due to its helpful components, it is especially suitable for critical systems. For example, if the PC motherboard application requires quick system voltage protection, the XC6121A421MR-G supervisors will be the perfect choice. Moreover, it well applied in embedded systems and various of system boards which need electronic devices protection.

For instance, XC6121A421MR-G can be used inside the storage drives and data storage systems, like hard disks, flash disks etc. It can also be used as a controller to monitor the voltage and temperature levels of the system. It can help to stop powers up the subsequent circuits in order to protect the system during the voltage or temperature out of normal range. The XC6121A421MR-G supervisors usually be used in industrial control systems applications, such as automation, smart grid, and advanced manufacturing field.

In the working principles of XC6121A421MR-G supervisors, its core part is to monitor the supply voltage of the system. The voltage level can be preset by the input voltage threshold adjuster through the LVD pin. The set voltage will alarm and activate the reset chip when the system supply voltage is above the threshold value. The reset output will be High once the delay circuit function is activated. During its operations, XC6121A421MR-G supervisors will not intentionally interfere the voltage surge and its power interruption, rather working in a circuit loop.

XC6121A421MR-G supervisors is Toshiba’s unique PMIC product, keeps the perfect balance between the space and cost requirements, provides the best support for system applications. This micro IC is capable to handle various application fields with its secure reset output and adjustable voltage values.
