host mode. The ILIM option header sets the output current limit. Current output is set to pro-
vide 100 mA.
In peripheral mode, the DEMO board may be powered from voltage input applied at the
miniAB USB connector. This limits overall board operation to 500mA maximum – see caution
above. This power input drives both the +3.3V and +5V power rails. See Power section above
to select this input.
USB Mode Select
The Mode Select option header configures the DEMO board for either HOST mode functional-
ity or Peripheral mode functionality. When set to HOST, the DEMO board will energize the
VBUS output to power attached peripherals. As noted above, this output will source a maxi-
mum of 100mA. When set to Peripheral mode, the miniAB USB connector may be used to
power the DEMO board.

Backup Power
A 1.5F Electric Double Layer SuperCap provides for backup power in the event primary power
to the board is severed. The SuperCap may be charged from either primary board power or
from a 2-position terminal block at J3. The terminal block is not installed default conditions.
Each input is diode protected to prevent back biasing in the event power is turned off.
CAUTION: Voltage input at terminal block J3 should not exceed 3.6 V.
The SuperCap powers the VSTBY input to the MCU during power failure incidents. The Su-
perCap provides sufficient charge to power the MCU for approximately 24 hrs during a power
failure.
VSTBY Input Select
Option header J4 allows the user to select the input voltage source used to charge the Su-
perCap. The SuperCap may be charged from the board power or from a terminal block at J3.
The J3 terminal block is not installed in default configurations.
