Interactive application notes tutorial

Getting started with Nexperia interactive application notes

Nexperia's Interactive application notes provide general guidelines for various power designs and topologies. A simulator is embedded inside the application with a predefined schematic. This simulator provides a direct view of the performance from system level down to individual component level.

Navigating to Interactive application note pages

To access the interactive application note pages, you can navigate from the ‘Application’ tab on the Nexperia main website page. Scroll down to the last section of that page to find the ‘Interactive application notes’ section.  By clicking on one of the interactive application notes, you will gain full access to the text of the system description which include embedded simulations.

Using the embedded simulator

Take IAN50001 - Reverse battery protection in automotive applications as an example to show how to use the embedded simulator. To open the embedded simulation, simply hover over the simulation image. Left click the start icon  to see the simulation result of the designed circuit.

The simulation will now open inside the interactive application note page.

Circuit schematic. Signal source, components connected with black lines.

Waveform of the chosen point.

Voltage, current, power dissipation and thermal can be tested.

Waveform viewer

There are 2 ways to view the simulation waveforms.

The first one is to view the waveform in the wave box displayed in the schematic. The other way is to check waveform in the wave viewer.

Set wavebox view

Click the probe and drag it into position. If the probe is at a wire or component terminal the default is to display voltage. If the probe stays at a component the required waveform(s) can be selected. Note I(p1) means the current flow into port 1 of the device. I is default.

Zoom in and Zoom out of waveform area

Left click and drag to the focus area you want to zoom in then release. The area in blue will be zoomed in. Right click then click View All, waveform will be zoomed out.

Waveform menu

Right click on waveform, a menu will be displayed as shown below:

Display Mode

Multi trace and Overlaid waveform views can be displayed in the wave box:

Multi trace view

Overlaid trace view



Waveform colors can be customized.


Click add cursor, the cursor will be added into waveform and relevant electrical reading will be displayed.

Download waveforms

Click download waveforms, the waveform data will be downloaded as a CSV (comma-seperated values) file, which can be opened in Excel.

Wave viewer

Press Plot in viewer, the waveform will be displayed in wave viewer.

Click  to open the waveform in a new window.

Math operations

Math operations are quite limited in wave box, only addition, subtraction, multiplication, and division can be used. It can be more useful when plotting waveforms in the viewer and using the waveform analyser.

Function summary for embedded simulation.

Enter SystemVision for further simulation functions

Click on Edit in (as shown in figure 3) to change the setting of the circuits. The main circuit will be shown in the centre. The circuit designers will be listed on the right of page.

Have fun with customized simulation yourself!
