Additional Details:

The XC6117E027MR-G voltage detector has a fixed detection voltage of 2.7V. The "MR" in the part number likely refers to the package type (SOT-25) and the tape and reel packaging. The "-G" indicates that the device is RoHS compliant and lead-free. Proper decoupling capacitors should be used to minimize noise and ensure stable operation. The output of the voltage detector is typically an open-drain output, which requires a pull-up resistor to provide a high-level signal when the voltage is above the detection threshold. The specific value of the pull-up resistor depends on the application and the load current.
