![]() RSET – This pin serves as the reset of the device, allowing the switch to open.We’ll be using the SOT23-5 package type, which requires 5 pins, including: Lucky for us Texas Instruments makes some impressive datasheets, and if you look on page 3 you’ll see the Pin Configuration and Functions heading. This summary is important when it comes to making your symbol, as it tells you exactly what pins you need and what their labels are without having to guess. Within most quality datasheets you’ll find both a table and drawing that gives a summary of all the pins and their intended functions for a device. Feel free to follow along with the TPS92411 datasheet. Let’s begin! Prep Step – Remember the Datasheetīefore we set sail, you’ll need to gather your datasheet! In our example, we’ll be making a symbol for a MOSFET switch from Texas Instruments. You can think of these symbols as the map to the chest of schematic treasure! Symbols show off all the functionality of your design without having to get into the nitty gritty of physical dimensions and packages. ![]() Regardless of what kind of design you’re creating, it all begins with symbols and schematics. Now, it’s time to continue on your journey by learning how to build your first symbol. Welcome back to the Library Basics Series, Pirates! In Part 1 you got your hands dirty creating your very first package in Autodesk EAGLE. 7 min read Library Basics Part 2: Creating Your First Symbol in Autodesk EAGLE
