Introduction

The XC6123A244MG-G is a type of PMIC (Power Management Integrated Circuit) supervisor, which is a device used to monitor power rails in electronic circuits. This is done by providing voltage or current level threshold comparison, allowing quick power rail assessment and preventing over-voltage and over-current events. It is used both to give warning indicators and to shut-down power rails in the event of a problem.

Application fields

The XC6123A244MG-G supervisor is used in a variety of applications, most typically in advanced microcontroller-based systems and programmable logic controllers. This makes it well-suited for applications that must maintain a safe power rail state in order to ensure the correct functioning of the system. Such applications may include intelligent lighting, LED display panels, industrial automation, and automotive systems.

Working principle

The XC6123A244MG-G operates by monitoring the voltage rail in a circuit. It features an adjustable voltage monitoring circuit which can send an alert signal (along with a reset/interrupt output) if the power rail goes above or below threshold levels. This is made possible through a reference voltage, which is typically set independently of the monitored voltage. Furthermore, the supervisor can be programmed to detect slow voltage drops or fast transients, both of which are critical events that could potentially damage the system.

In addition, the device also features open drain outputs, an active low reset signal, and a power-on reset functionality. This allows the XC6123A244MG-G to provide both a warning indication as well as shut down the power rails when the monitored voltage is outside a predetermined range. By combining the features of the supervisor with external components, multi-phase power monitoring can be achieved.

Conclusion

Overall, the XC6123A244MG-G is a highly versatile PMIC supervisor that can be used in a wide range of applications where precise power management is essential. By combining the adjustable voltage monitoring circuit with the active low reset signal and power-on reset functionality, the XC6123A244MG-G can be used to quickly indicate and shut down power rails in the event of an over-voltage or over-current event.
