I was exploring one of the popular Tiva C launchpad (http://processors.wiki.ti.com/index.php/Tiva_C_Series_LaunchPads) to create a custom board based on TM4C123GXL evaluation kit.
There is a Schottky diode connected to the RESET output of the voltage supervisor in the schematic as shown below
One of the anodes goes to the RESET pin of the main microcontroller and the other one to the RESET pin of another microcontroller which act as an inbuilt debugger/programmer.
What is the use of a Schottky diode in the output of a voltage supervisor like this?
Note : +VBUS is the +5V coming from USB connector
