Power Supply
The EV kit peripherals are powered by a user-supplied
USB port at J1 or by a 5V DC power supply connected
between V_EXT and GND. Jumper JU3’s position selects
the power source. With a shunt shorting pins 1-2 on JU3,
the EV kit is powered at V_EXT, while a shunt shorting pins
1-3 means that the EV kit is powered by the supply pres-
ent at the input of the device. Placing the shunt on pins
1-4 on JU3 allows the peripheral devices to be powered
from an external power supply connected at TP3. The
device must always be powered by an external supply
connected at TP6 or BP1. See Table 1 for jumper settings.
Flag Indicator LED
The EV kit includes a built-in LED to give visual notifica-
tion of an overcurrent fault. If jumper JU10 has a shunt
installed at 1-2 and jumper JU2 has no shunt installed,
then an overcurrent fault causes LED2 to glow red. See
Table 1 for jumper settings.
Preset and Adjustable Current Limits
The EV kit includes three common overcurrent limits
as jumper-configurable options, as well as a fourth
jumper-configurable option for an adjustable limit. Set the
current limit to 250mA and install a shunt across pins 1-2
on jumper JU1. For the 1.5A current limit, install a shunt
across pins 3-4 on JU1. For the 2.5A current limit or the
adjustable limit, install a shunt across pins 5-6 or 7-8 on
JU1, respectively. The adjustable limit is set using the
potentiometer (R16). See Table 1 for jumper settings.
