Application fields and working principles of XC6122D733MR-G are an important part of Power Management IC (PMIC) Supervisors. This PMIC includes a precision voltage detector (AVDD), two power key inputs, a watchdog timer, and two 4-pin reset outputs. This device is one of many supervisory PMICs offered by XCORE.

The precision voltage detector of this PMIC provides a voltage-controlled reset (VCR) output. This output will reset a MCU, DSP, or any other logic device, depending on the voltage applied. The voltage detector is built into the PMIC and, therefore, the design of the system is simplified. The device has a low operating current with a maximum detection voltage of 6.7V. This allows the device to precisely detect the voltage and provide an accurate reset result.

The PMIC also offers two power key inputs. These two power keys are used to control the level of reset signal, which can be set to input a high, low, or high-z signal. The high-z option will result in the reset signal being inactive, allowing the system to enter into normal operation. The user can also set one of the power keys to enable the watchdog timer when it is active.

The watchdog timer, or WDT, is a timeout features that is included with the PMIC. It is used to monitor the system and will reset the processor when the timeout period has expired. The WDT can be configured to reset the system after a certain period, or to generate and interrupt signal. To ensure the accuracy of the timeout period, the WDT is integrated with a precision oscillator.

The XC6122D733MR-G also offers two 4-pin reset outputs. These outputs are independent of the reset signal generated by the voltage detector and WDT. They are also programmable to a wide range of new reset conditions. This includes an output signal that will indicate when the device has been able to maintain the system power for a certain duration, or when the power supply has reached a certain level. With this feature, the user can monitor the health of their system to ensure maximum uptime.

In summary, XC6122D733MR-G is a powerful PMIC supervisor that offers a wide range of features. It offers a precision voltage detector, two power key inputs, a watchdog timer, and two 4-pin reset outputs. These features provide the user with a highly accurate and reliable reset system, which can help ensure the fault free operation of their systems.
