In this electronics basics episode we will have a closer look at eFuse ICs. They offer a ton of protection features for a very small price tag. That is why I will show you how I used such an eFuse in my LiPo Supercharger project and how you can use it for pretty much every electronics project. The included protection features are the following: undervoltage, overvoltage, reverse voltage, overcurrent and short circuit current. Let's get started!

Very cool. There might be a big market for eFuse demo boards with trim-pots for adjusting voltage and current control, and Pheonix connectors so people could wire these into their projects. Post-assembly powered functional testing would be a great application. I can't tell you the number of times I've seen small circuits boards scrapped during manufacturing because there was a short somewhere that damaged something on first power up (during functional testing). By controlling the power to the UUT, these could even protect against damage to other components in a system or the test equipment, to some extent.

Great, maybe this is my next solution, working with colleagues capable of breaking anything they touch... One thing I've learned at work is: _Regardless of the amount of protection I put in my circuits, my (non-tech) colleagues will always find a way to destroy them..._ They have: - Put a powered PCB on top of a metal table, during testing... - Ripped a USB-B port of my board, trough hole version... - Reversed the polarity, on a prototype in which I told them to wait on me before powering it... - Used the wrong adapter / battery / voltage... - Used it outside without proper watertight enclosure... - Put multiple PCB's on top of each-other, while powered... - Peeled of a 0402 capacitor, because they thought it looked like a dirty breadcrumb... - ... I would dare the military to lend them one of their armored vehicles, for testing purposes. My colleagues would probably break it within the next 5 minutes, by just looking at it.

I discovered that, having laboured long and hard on the project, it draws so little current that the power banks I've tried to used to power it simply switch off. We're back to batteries and the inevitable possibility of some klutz (likely me!) getting the power in wrong. As ever, great video. Thanks 😊

It's an absolute non-feature, they should at least make it possible to disable. I guess you could always add a parallel power resistor that burns off some extra current to make the ""smart"" power bank know you don't want it to shut down. Sounds incredibly stupid when thinking about it, intentionally wasting power of a battery... Good lord, modern electronics.

@@westelaudio943 yup, the extra resistor running in parallel would likely do the deed, but we're agreed that this is a complete waste of power.

Probably pointed out already but so far the comments I have read did not say it. What I generally do to add a simple reverse voltage protection, is just using an bridge rectifier. There is a small drop in voltage but in the cases I have used it, it does not really mater. With this, more than a protection it allows to use whatever polarity you give to it. Did not know of these circuits either.
@jensschroder8214 3 жыл бұрын
The other day I connected a 3.3 volt voltage regulator to 12 volts. Switching the switching power supply on and off went well several times. But when switching, the power supply unit must have charged itself to over 14 volts, limit of the V regulator. The voltage regulator short-circuited and the circuit behind it suddenly had 7 volts. I heard the 4 volt tantalum capacitor explode. The IC behind it was specified up to 5.5 volts, but survived. From my box I then put a diode and a 78L12 in front of the new 3.3 volt voltage regulator. So the 3.3 V regulator doesn't see more than 10 to 12 volts, that's in the rules. The 78L12 will not be able to regulate well with a 12 volt input, but it will certainly withstand voltage peaks. I didn't have a 78L09 that would be the better choice. Another possibility would be to build a 3.3 volt regulator with an LM317. But I didn't have any space left.

Just now I checked and they charge $7.99 to ship an order via UPS ground, UPS 2nd day, or FedEx 2nd day. They have no minimum order requirement. Tbh, it isn't worth placing a small order.

That's a good solution for a fixed power circuit but if you're using batteries you're reducing your voltage headroom by whatever the diode reverse voltage is.
