SELECTING TARGET POWER
FIGURE 2-4:
The PICkit 2 can supply power to the target or the target may be powered externally.
2.5.1
If you are going to power the target board from the PICkit 2, do not attach a power sup-
ply to the target or the PICkit 2 will sense it and not give you the option to use PICkit 2
power. For a target board not connected to an external power supply, you will see the
options displayed in Figure 2-5.
FIGURE 2-5:
To enable power to the target device, check the V
The default setting is “Off”, i.e., the checkbox is unchecked.
The voltage supplied to the target may be adjusted before or after enabling power by
adjusting the V
If a short or heavy current load is detected on the programmer-supplied V
will receive an error and V
The USB port current limit is set to 100 mA. If the target plus the PICkit 2 exceed this
current limit, the USB port may turn off. The target may be powered externally if
more power is required.
Note:
Target Powered from PICkit 2
If a target power supply is not detected, the PICkit 2 will always supply
power to the target during programming, regardless of the V
“On” checkbox state.
