Power Management Integrated Circuits (PMIC) are devices which are used to manage the power supply and voltage regulation of microelectronics systems. The XC6123C221MG-G is a Supervisory PMIC designed to monitor the operations of different devices within microelectronic systems and provide protection functions, system start-up and voltage monitoring.

The XC6123C221MG-G provides three primary functions for microelectronic system operation and protection. The first is a voltage monitor, which monitors the system voltage against specific boundaries and trips when the voltage rises beyond the upper limit or drops below the lower limit. This helps prevent damage from unregulated power supplies and ensures the system controller operates within the required operational parameters.

The second function of the XC6123C221MG-G is a system start-up circuit. This circuit allows for a power-on reset of the microcontroller when the system is first powered-up. This ensures the controller begins executing in a known state and prevents any accidental interruptions in the system operation caused by system hang-ups.

The third function of the XC6123C221MG-G is a protection circuit. This circuit strides to protect the microcontroller and other devices within the system from damage caused by over-voltage, over-current and other external interferences. It does this by disconnecting the system from external sources and preventing any further operation until the conditions are corrected.

The XC6123C221MG-G is ideally suited for use in microelectronic systems which require reliable voltage monitoring, system start-up and protection against potential hazardous external interferences. In addition, it is designed with a low threshold voltage of 1.3V and a wide operating temperature range of -40°C to +125°C, making it suitable for use in industrial and automotive environments.

The XC6123C221MG-G operates on a continual basis, constantly monitoring the system voltage, and is triggered when the upper or lower limits of the voltage window is breached. When this happens, the device will trigger a reset or interrupt signal, depending upon how it is configured, to allow the system controller or other systems to take evasive action in order to maintain stable operation.

The XC6123C221MG-G utilizes a set of internal resistors connected to the input supply in order to determine the current voltage, which is then compared by an internal voltage comparator. This, in addition to its internal integrated circuits, results in a low power consumption of only 0.1 μA.

The XC6123C221MG-G is a highly reliable solution for microelectronics systems requiring voltage monitoring, system start-up and protection. With its low power consumption and wide operating temperature range, it is ideal for use in industrial and automotive systems. In addition, it can be quickly implemented in any microelectronic system, making it a cost-effective solution for any application.
