XC6123C450MR-G is a member of the range of PMIC (Power Management IC) - Supervisors. This type of integrated circuit prevents the majority of complex electronics from possible damages and system losses due to drastic events, such as over voltage and over current. In other words, XC6123C450MR-G is a fail-safe supervisor integrated circuit.

In general, the main functions of XC6123C450MR-G are voltage detection, voltage selection, and output control. Its applications can be found in a wide range of consumer and digital systems, such as portable multimedia devices, digital cameras, gaming devices, computers, mobile phones, and automotive systems. In order to understand its working principle, it is necessary to take a look at its two major components – the voltage detection block and the voltage selection control block.

The voltage detection block of XC6123C450MR-G consists of a voltage divider, a voltage reference, and a comparator. The voltage divider is designed to sample the primary supply voltage. The voltage reference is used to set the reference voltage to a certain level. This is usually higher or lower than the primary voltage depending on the application. The comparator is then used to compare the voltage reference signal with the sampled voltage. If they do not match, then the comparator will signal an error. The result is used to trigger the output control block.

The voltage selection control block of XC6123C450MR-G consists of an analog multiplexer and a digital logic circuit. The multiplexer is used to select the appropriate voltage. The logic circuit is used to control the multiplexer. Depending on the voltage reference signal, the logic circuit will determine which supply voltage should be selected. This is done by signals sent to the multiplexer and the output control block.

XC6123C450MR-G guarantees great stability over temperature and it is capable of working with voltages from 1.8V up to 5.5V. With such features, XC6123C450MR-G is a great choice when it comes to reliable power management in a variety of applications.
