AA battery replacement project tutorial #4: PMIC

This entire project is intended to be done within the free trial period.
[This is Part 4 of the tutorial, for Part 1 click HERE]
Open Schematic
Double click your saved schematic to open and continue where we left off from
New Schematic Sheet
Let’s create a new schematic sheet. Do you remember how to do so?
… Yup! You can just look it up as in the image below:
Pro Tip:
You can pin the menus you like anywhere,
you can also set shortcuts for them,
OR check which shortcuts already exist.
You can ask the ✨Product Support Copilot✨ how to do any of this.
Another Pro Tip:
There are two types of shortcuts:
- Regular Keyboard shortcuts
- Mouse “strokes” , as in just draw any shape with your mouse!
There are already default ones set for you, but you can set your own or change the default ones too!
Design Navigator
Make sure your Design Navigator is open. If it isn’t, you can use the search tool to find it and pin it.
You can also right click on the sheet in the Navigator to rename it:
PartQuest – Reminder!
Here is what we covered in the previous lesson about how to import parts.
Refer to this for the next section!
Reminder Start:
Using the Search Tool again, look for PartQuest and click it
In the search box, look up our battery charger by entering its part number MCP73871-2CCI/ML as in the image below
Drag and drop the part into your Project Explorer menu as in the image below
Click and drag into your schematic as in the image below
Reminder End 😏
External Components
Now, let’s use this reminder to find the following components and add them to your schematic:
- ERJ3EKF1001V
- MCT06030C1002FP500
- 150060GS75000
- 150060SS75000
- SMLEN3BC8TT86
- CL21A106KOQNNNE
- B57620C5103J062
- RC0805FR-0710KL
- RC0603FR-07100KL
Arrange Components
Arrange your components so that they look something like the image below.
Circled in yellow are 0R resistors. They appear a different size for now, but we will cover this in the next step!
Pro Tip:
Click CNTRL + R to rotate components
ANOTHER Pro Tip:
Want to turn off pin number attributes?
Of course, you can ask the Product Support Copilot how to. But here’s a quick way to do it:
- Double click the actual PIN itself
2. When the properties tab opens, simply untick the pin number
Scale Components Symbols (grow/shrink)
You might want to make your 0R links smaller than the rest of the components. If so, the steps are:
- Click the component you want to scale to a different size (I did this for all the 0R)
2. In the search tool, look up “scale”
3. Choose the scale factor you like
Place Power Symbols
There are many ways to place a power symbol.
My favourite is always to find anything I want through the search bar as in the following image.
Once you place it, you can right click to select properties, and change its Global Signal Name property.
Create three:
- VUSB
- V_BUCK_IN
- VBAT
Place them as in the following image:
Place Ground
You guessed it, you can just look this one up too!
Now place GND as in the following image:
Place Net
Pro Tip:
Click n (lower case) to place a net
So go do your thing and place nets to connect components as in the following image:
Place Text
Yup, look it up through the search bar and you can find it in an instant!
Now, can you guess how to edit it?
If you guessed right click → properties, then you’re absolutely correct!
Place text as in the image below, or wherever you see fit:
Import Image
I like to import relevant equations from the datasheet. You can use screenshot copy/paste to import equations if you like.
Reference Designators
We will do this at the very end, so worry about this for now!
That’s it for today!
Close your project, and let’s continue next time. Let me know if you enjoyed this tutorial in the comments!
And if you are struggling with anything, post your issue in the comments and I’ll get back to you as soon as I can.
Have a wonderful Xpedition!
