The XC6123E731MR-G is a 4-channel power-management integrated circuit (PMIC) with supervisor function. It is designed for applications requiring accurate voltage monitoring and protection such as microprocessor systems, microcontrollers, and digital signal processors (DSPs).

The XC6123E731MR-G provides four channels of power-management functions, with two channels of VCC and two channels of VDD. The VCC output voltage can be set to any value between 3V and 24V, and the VDD output voltage can be set to any value between 0.8V and 12V. Both types of outputs can be used to enable power supply sequencing and power-on reset circuits, as well as to provide supervisor functions. The VCC and VDD channel outputs can be independently configured to source and sink current or to be in high-impedance state, enabling them to be used in various types of systems.

The XC6123E731MR-G also provides monitoring functions for voltages and currents. Internal comparators can monitor the VCC and VDD channel outputs for over-voltage and under-voltage conditions and provide a push-pull output signal for each channel. A normalized input voltage between 0V and 4V can be used to detect current fault conditions, such as over-current, under-current, and short-circuit conditions. The device also features an internal reference voltage, allowing for precise voltage monitoring of the output voltage of the power supply.

The XC6123E731MR-G has an on-chip analog-to-digital converter (ADC) which can be used to measure the output voltages of the power supply, allowing the device to further monitor and protect the system within specified parameters. The ADC can be used to determine the load current of the system and initiate the load switch or reset of the system in case of an over-current or short-circuit condition. This ADC can also be used to measure the input voltage of the system and detect any fault conditions in the input power supply.

The XC6123E731MR-G also includes an on-chip digital interface which enables the user to access data and control the device over a 3.3 V or 5.0 V bus. This interface can be used to monitor voltages, currents, and temperature, as well as to control the device functions and set parameters.

The XC6123E731MR-G is a highly integrated PMIC with supervisor functions, providing an all-in-one solution for power management and system protection in high-end microprocessor systems and digital signal processors. It features high accuracy voltage monitoring and protection, as well as advanced current sensing and protection. The on-chip analog-to-digital converter and digital interface enable the user to monitor and control the device, allowing it to be used in complex power management systems.
