The components at U11 and U12 guarantee electronic protection
against overvoltage and excessive current draw at pin 6 of P1A; in
particular:

•

Load detection and controlled voltage supply switch-on:

In order to ensure clear detection of the switch-on condition,
the connected device should cause a current draw of at least 10
mA at pin 6. The controlled voltage supply switch-on prevents
voltage drop off on the phyCORE Development Board LD 5V.

•

Overvoltage Protection:

If the voltage at pin 6 exceeds the limiting value that can be
provided by the phyCORE Development Board LD 5V, the
voltage at pin 6 will be switched off immediately. This prevents
damage to the phyCORE Development Board LD 5V as well as
connected modules and expansion boards.

•

Overload Protection:

If the current draw at pin 6 exceeds the limiting value of
approximately 150 mA, the voltage at pin 6 will be switched off
immediately. This prevents damage to the phyCORE
Development Board LD 5V and its power adapter caused by
current overload.

This configuration option provides the following possibility:

Jumper
