Additional Details

The R5405L276KE-TR features a fixed detection voltage, typically around 2.7V, as suggested by the '27' in the part number. The 'TR' suffix usually indicates tape and reel packaging for automated assembly. The output of the voltage detector is generally an open-drain or CMOS output, which can be used to directly drive the reset input of a microcontroller or other digital device. The datasheet should be consulted for precise specifications such as detection voltage accuracy, reset timeout period, and operating voltage range.
