TriBoard Information
+3,3V via LDO directly from pre regulator (used by Ethernet PHY and on board memories if assembled)
Applying a stable supply voltage causes the power on reset after a short period. The three LED's (V_UC, +3.3V,
+1V25) indicate the status of the on board generated voltages.
A manual power on reset is executed by pressing the reset button.
The Board has to be connected to a +3,5V to +40V DC power supply.
The power consumption is not specified yet but a supply with 12V and more than 500mA is recommended. The
pinout for the supply connector is shown in Figure 6-4. There can be used any standard power pack with a
connector where the positive line is surrounded by the ground line.
3.3.1 Failsafe handling
In case that the device don’t contains a program which disable or service the window watchdog and error pin
monitor of the TLF35584 then the TLF35584 is going to a FAILSAFE state where all supplies are switched off. This
state can be left via reconnect the power plug or via the ENA button (S502). In this case you must connect a
debugger which is able to disable the window watchdog and error pin monitor to reprogram the microcontroller.
In the default state of the board the switching to FAILSAFE state is switched off via resistor R508.
If you will use/evaluate all safety features of the TLF35584 remove assembled R508. Make sure that you have a
proper initialization of TLF35584 in your software.
Resistor R508 is red marked in the following Figure 3-1:
