As the power management integrated circuit (PMIC) field continues to expand and technology becomes increasingly complex, one of the components in particular that has gained widespread use among developers and engineers is the XC6123C345MR-G supervisor. This component is part of the XC6123C345MR-G family of supervisor products specifically designed to provide the operating control and protection of microprocessor (MPU) while reducing power consumption.

The XC6123C345MR-G is a low cost, self-contained Voltage Supervision circuit which provides voltage monitoring, reset, and sequencing functions. It also contains power-on-reset and under-voltage monitoring. This supervisor is designed to provide a robust voltage monitoring feedback loop for the critical system voltages which, when combined with its low power consumption, makes for a strong component for any control or protection circuit.

The main applications for the XC6123C345MR-G supervisor are in applications that require powering, protection and sequencing of microprocessors (MPU), flash memory, and even voltage regulators. Its low power consumption and sophisticated methods of voltage protection make it suitable for low power systems such as battery operated systems and portable applications. It is also particularly popular in applications that require ultra-reliable power management.

When it comes to working principle, the XC6123C345MR-G has two different types of operation: single-stage reset and sequential reset. In single-stage reset, the supervisor monitors the voltage level of all of its monitored inputs, and in the event of an over voltage or under voltage, a reset is initiated. Sequential reset, on the other hand, is a two-stage process. The supervisor first monitors the voltage level of each monitored input, and if an over or under voltage is detected, it then performs a first-stage reset. This reset outputs an internal non-inverting signal that triggers the next stage, where the second reset is initiated.

The XC6123C345MR-G also features integrated ESD protection, temperature-compensated reset, filter delay circuit, power-on reset circuit and a maximum input voltage of 4.5V. It has an operating temperature range of -40°C to +85°C, as well as a storage temperature range of -65°C to +125°C.

Overall, the XC6123C345MR-G is a great choice for low power applications that need reliable voltages monitoring and protection. Its single-stage and sequential reset operations make it suitable for both new designs and existing designs that need a reset synchronization. Furthermore, its low power consumption and ESD protection capabilities, along with its temperature-compensated reset, filter delay circuit and power-on reset circuitry make it an ideal fit for ultra-reliable power management applications.
