Application Kit Information
3.1
Power Supply
The microcontroller needs 3 different supply voltages. This voltages are generated via
Infineon’s Multi Voltage Safety Micro Processor Supply TLF35584QV (+3,3V and +5V
volt for ADC and CAN) and via the microcontroller itself (+1,3V).
Applying a stable supply voltage causes the power on reset after a short period. The
LED' (+3V3) indicate the status of the 3,3V voltage.
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.
A manual power on reset is executed by pressing the reset button.
3.1.1
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 500mA is sufficient. The pinout for the supply connector is shown
in
. There can be used any standard power pack with a connector where the
positive line is surrounded by the ground line.
3.1.2
Power via Micro USB (BU301)
The Board can also be powered by the Micro USB connector. The power consumption
of the board is approx. 400mA. Use an USB port which can deliver 500mA (USB 2.0) or
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
.
3.1.3
Multi Voltage Safety Micro Processor Supply TLF35584QV
The board has assembled the Safety Micro Processor Supply with the following
Features:
•
High efficient multi voltage power supply chip
•
Serial step up and step down pre regulator for wide input voltage range from 3.0 to
40 V with full performance and low over all power loss
•
Low drop post regulator 5.0V/200mA for communication supply (named LDO_Com)
•
Low drop post regulator 3.3 V/600 mA (VS2) for
μ
C supply (named LDO_
μ
C)
•
Provides enable, sync out signal and voltage monitoring (inside device to be added
to reset function) for an optional external post regulator for core supply (not used)
