PMIC – Supervisors: XC6123D750MR-G Application Field and Working Principle

PMIC (Power Management ICs) are integrated circuits (ICs) used to supply and manage the flow of electricity and power within a system. PMIC supervisors, in particular, provide an efficient means of intelligently managing power within a system. An example of this is the XC6123D750MR-G PMIC supervisor which provides over-voltage and under-voltage protection, brown-out protection, power fail detection, and power sequencing, among other useful functions typically integral to supervisors.

The XC6123D750MR-G is an advanced supervisor IC from Diodes Incorporated that is capable of providing multiple voltage protection, brownout protection and power fail detection. The XC6123D750MR-G offers a wide supply voltage range of 4.5V – 36V and includes circuit control logic for monitoring and managing the supply. The XC6123D750MR-G has a wide variety of applications for high power systems such as server, computing and networking. A typical application is described below.

Application

The XC6123D750MR-G supervisor is well suited to a wide variety of industrial applications. When used with a microprocessor-controlled system, the XC6123D750MR-G can provide advanced power sequencing to ensure that the system’s critical components are always operational. This can be particularly important in high power, server applications where it is necessary to provide system reliability.

In server applications, it is beneficial to have the ability to monitor and protect the power supply from unexpected power fluctuations, over-voltage or under-voltage conditions. The XC6123D750MR-G supervisor is an ideal solution for these applications, by providing power fail detection, power sequencing, over-voltage and under-voltage protection, and brownout protection.

In addition, the XC6123D750MR-G can be used to enable a system’s critical components to remain functional even under conditions of power interruption or power failure. The XC6123D750MR-G allows for reliable power sequencing, enabling the system to respond gracefully to unexpected power transients or interruptions. This eliminates the need for costly explicit management of these conditions, as the XC6123D750MR-G automatically handles the task.

Working Principle

The XC6123D750MR-G supervisor is based on a dedicated voltage supervision architecture which requires only limited external components to be added to the system. The XC6123D750MR-G is designed to monitor the power supply using an adjustable threshold. This adjustable threshold is used to establish an upper and lower voltage threshold for the supply voltage. If the supply voltage exceeds the upper threshold or falls below the lower threshold, then the corresponding protections are applied.

The XC6123D750MR-G also has the capability to sense power fail. If a power fail is detected, then the XC6123D750MR-G initiates a reset signal to the system. This reset signal can be used to gracefully shut down the system’s components in the event of a power failure. Furthermore, the XC6123D750MR-G can also detect a brownout condition and provide a reset signal accordingly. This feature allows the system to close any open processes in the event of a power outage.

The XC6123D750MR-G also has the capability to detect over-current or over-temperature conditions, and to provide a signal for the system to take appropriate action in the event of these conditions. Furthermore, the XC6123D750MR-G can also provide power sequencing for the system, enabling critical components to remain functional even under conditions of power interruption or power failure.

Conclusion

The XC6123D750MR-G PMIC supervisor from Diodes Incorporated is an effective solution for providing power monitoring and protection in high power server applications. The XC6123D750MR-G is designed to provide high levels of protection and power management, including over-voltage and under-voltage protection, brown-out protection, power fail detection and power sequencing. The XC6123D750MR-G also offers the ability to detect over-current and over-temperature conditions, and to reset the system if these conditions are detected. Furthermore, the XC6123D750MR-G can enable a system’s critical components to remain functional even under conditions of power interruption or power failure.
