Introduction:

The XC6122C249MG-G is a programmable load supervisory with power-on reset and watchdog functions. This IC provides comprehensive power supply and system reset for industrial, scientific and medical (ISM) applications. It is designed with a high voltage internal NAND gate and a low voltage external circuitry, allowing reset at a precise time and voltage. It provides protection against over-load, under-voltage, over-temperature and over-current. This article will discuss the application fields and working principle of the XC6122C249MG-G.

Application Fields:

The XC6122C249MG-G is designed for use in industrial, scientific, and medical applications. It can be used for system monitoring, detecting power-line issues, power sequencing, memory testing, and system resetting after a power failure. It is suitable for use in computers, laboratory and medical equipment, industrial controls, test and measurement systems, and automotive electronics. Additionally, it can be used in portable devices such as smartphones, tablets, and cameras. Other applications include medical electronics, microcontrollers, instrumentation, and satellite systems.

Working Principle:

The XC6122C249MG-G is a programmable load supervisory with power-on reset and watchdog functions. It is designed to provide power supply monitoring and reset in industrial, scientific and medical applications. The IC is designed with two integrated circuits connected in series, the low voltage LV11XC6 and the high voltage XC6122C2. At power-on, the high voltage XC6122C2 IC monitors the power supply voltage to detect any overvoltage events. Once it detects an overvoltage, it latches off the low voltage LV11XC6 IC, resulting in a reset. The reset will remain active until the voltage is restored to within an acceptable range. The low voltage LV11XC6 IC is designed to monitor the power supply voltage at a preset voltage threshold. If the voltage falls below this threshold, it will initiate the reset. Moreover, the device includes a watchdog timer to reset the system in case of a system fault.

Conclusion:

The XC6122C249MG-G is a programmable load supervisory with power-on reset and watchdog functions. It is specifically designed for use in industrial, scientific and medical applications, such as computers, laboratory and medical equipment, industrial controls, test and measurement systems and automotive electronics. The device includes two integrated circuits connected in series, the low voltage LV11XC6 and the high voltage XC6122C2. The high voltage XC6122C2 monitors the power supply voltage to detect any overvoltage events and the low voltage LV11XC6 monitors the power supply voltage at a preset voltage threshold. Additionally, the device includes a watchdog timer to reset the system in case of a system fault.
