Are there any short circuit protection or voltage supervisor circuitry?

Solution

Yes, the HES7 board is equipped with voltage supervisor circuitry, which protects the whole system from short circuit, undervoltage, or overvoltage conditions. Additionally, it is responsible for the proper voltage regulator power up sequence. Any deviation from the default state causes an immediate power down of all voltage regulators and a proper error code on the D2-11 status LEDs.
