When Connected to Computer
When the MPLAB PICkit
4 is connected to the
computer and in the MPLAB X IDE or MPLAB IPE application, use the supplied USB cable
between the computer and the Micro-B USB connector located on the top of the tool.
When Programming a Device Using PTG
When the MPLAB PICkit
4 is connected to
the remote target board for programming a device using Programmer-To-Go, the minimum
power required from the target board to the MPLAB PICkit
4 is 350 mA.
If sufficient power cannot be supplied from the target board, then MPLAB PICkit
4 must be powered by a 5V power supply
through the Micro-B USB connector on the top of the MPLAB PICkit
4 tool. There are several options for providing power, such as,
using:
- Any available PC USB port or USB hub port (no USB communication is
necessary; it is only used to provide power).
- A USB host port on a portable device.
- A USB power adapter or charger with a USB Micro-B connector, either
from an automotive power jack or an AC wall plug.
- A portable battery charge or power
source for cell phones or other portable devices with USB Micro-B connector.
- A custom battery pack that supplies
regulated 5V into the MPLAB PICkit
4 USB
Micro-B connector.
The USB power source used should meet the following minimum criteria:
- Is able to supply at least 350 mA
of current to the MPLAB PICkit
4 tool.
- Provides a steady, regulated 4.5V to 5.5V output.
Notes:
- 1.Most portable chargers/power devices with their own batteries will
not give an indication when their internal battery voltage gets low and the
output drops below 4.5V. Therefore, you must be sure the device’s battery has
sufficient remaining capacity to power the MPLAB PICkit
4 above 4.5V.
- 2.Any battery-based power sources should be disconnected from the MPLAB PICkit
4 unit when it is not in use.
Otherwise, the MPLAB PICkit
4 unit will
drain the power source battery.
