Power monitoring ICs (PMICs) are specialized semiconductor integrated circuits designed to monitor and protect individual power supply rails typically found in most electronics systems. PMICs have arisen as a major force in the electronics industry due to their low cost, power efficiency, small size, and expandable features. The XC6122E717MR-G is a 6-pin PMIC specifically designed for ultra-low-power applications. It offers several features, such as over-current protection, over-voltage protection, device-level monitoring, and battery backup.

The most distinguishing feature of the XC6122E712MR-G is its ability to detect and analyze any unexpected event or disturbance in the system, such as a surge in current or voltage, and respond promptly by either resetting the system or by temporarily shutting down all power rails. This feature allows the XC6122E712MR-G to detect and protect against system faults and maintain the integrity of the system in the event of an unforeseen event. This PMIC is classified as a supervisor, meaning it is designed to monitor and protect the system rail power supply and reset the system if necessary.

1. Application Field

The XC6122E717MR-G is ideal for ultra-low power applications that require an efficient and reliable power source. Because of its small size and power-saving features, the XC6122E717MR-G is suitable for use in medical and energy-saving applications such as medical monitoring systems, energy-saving white goods, and other home electronics.

It is highly recommended for use in industrial and commercial applications like CNC machines, test and measurement equipment, robots, and other automation machines, as well as consumer electronics such as remote controls, mobile phones and other portable electronics.

The XC6122E717MR-G works well in consumer robotics and drones, due to its ability to detect and react to any power glitches. This PMIC can also be used in automotive electronics, helping to ensure the safety of vehicle occupants and monitoring the power rail for any abnormal current or voltage.

2. Working Principle

The XC6122E717MR-G operates using a state machine operating in an open loop mode. It monitors the input voltage levels and output signals through analog-to-digital (A/D) converters. The A/D converter senses any voltage or current spikes and compare them to the reference voltage level. If the difference between the two values exceed the specified threshold, the PMIC will shut off the power rail or reset the system depending on the programmed maximum level. The PMIC can also protect against over-current and over-voltage issues.

When the power rail is disconnected the PMIC monitors the power supply for any sudden changes. If any fault or disturbance is detected, the PMIC will alert of the fault by resetting the power rail or shutting off the power. The XC6122E712MR-G also has an input signal monitor that can detect and report any fault or disturbance on the power supply.

The XC6122E712MR-G also has a sophisticated time delay circuit that can be used to provide an adjustable lag time to the system reset or power rail shut-off features. This time delay can be adjusted by the user to allow more time to respond to any power anomalies before resetting the system or shutting off the power rail.

In addition, the PMIC also has integrated protection circuitry such as over-voltage protection, over-current protection and device-level monitoring. This ensures that the power rail is running at the correct voltage and current level by comparing the input voltage, current readings and stored thresholds. This integrated protection circuitry prevents any system faults from occurring due to power-supply related issues and prolongs the system’s life.

The XC6122E717MR-G is an advanced PMIC and an ideal solution for many applications including medical imaging, industrial automation, consumer electronics, and automotive applications. Its integrated protection and monitoring features make it an ideal choice for applications that require a reliable and efficient power source.
