3.2 Power Supply
All needed voltages are generated via Infineon’s Multi Voltage System Supply TLF3068xQVS01.
The board works with 3,3V IO.
The TLF3068xQVS01 provide the following voltages:
+3,3V for TriCore (connected to VEXT, VDDP3, VFLEX and used by RTC, Ethernet Phy, display and SD card)
+5V supply (connected to VDDM and VAREFx and used by CAN transceiver and acoustic beeper)
+1,25V for TriCore (connected to VDD)
Applying a stable supply voltage causes the power on reset after a short period. The LED (+3V3) indicate the status
of the cpu voltage.
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 board can be powered directly by USB or by the power connector. In case that the voltage on the power
connector is higher than the 5V from the USB then the board is powered by power connector.
3.2.1 Power via supply connector (X101)
The Board has to be connected to a +5,5V to +40V DC power supply.
A supply with 6V and 800mA is sufficient. The pinout for the supply connector is shown in Figure 6-2. There can be
used any standard power pack with a connector where the positive line is surrounded by the ground line.
3.2.2 Power via Micro USB (BU301)
The Board can also be powered by the Micro USB connector. The power consumption of the board is higher than
500mA. Use an USB port which can deliver 900mA (USB 3.0). Most USB hubs are not able to drive more than
100mA and can’t be used.
Also it is possible to power the board with a cellular battery charger which has 5V output and use Micro USB for
connecting.
The pinout for the USB connector is shown in Figure 6-3.
3.2.3 Multi Voltage System Supply TLF3068xQVS01
The board has assembled the Safety Micro Processor Supply with the following Features:
– High-efficiency multi-rail power supply chip optimized for the use in advanced driver assistance systems
(ADAS)
– Step-down pre-regulator for wide input voltage range from 3.7 to 35 V (40 V limited time) with low over-all
power loss and fast transient performance. Suitable for operation with ceramic capacitors
– High-efficiency step-down post regulator for second output voltage generation
– Step-up post regulator with 5 V output voltage
– Voltage monitoring for two external voltage rails including enable signals
– Safe state control with safe state output (not with TLF30682QVS01)
–16-bit SPI
