Check out the ADVANCED SENSE Guide

Speaking of high-side power switches with protection and diagnostic functions, have you read Infineon's ADVANCED SENSE Calibration and Benefits guide (http://tinyurl.com/ADVANCED-SENSE-1-0)?

As an aside... I happen to know that the guys who wrote this little rascal are incredibly clever and handsome and witty ... the words all appear to have been hand-picked at the crack of dawn while the morning dew is still glistening on them, and it goes without saying that the quality of the diagrams is fantastic...

 Are these things expensive?

This is an incredibly complex question. What is a good price for me is really expensive for someone designing for the mass market. Before I overwax philosophical though, it seems to me you are only interested in a single unit, so I will only state the price from Digikey for the automotive version AUIR3314S is C$4.81. (C$1 is approx US$1.) Apparently it is still available in a TO220 pack, if you want ease of connection although you may struggle to find it in that format although I see Digikey have 6 at C$6.95 at the moment and Mouser have it in abundance.

Thanks, Aubrey.  I was thinking of using it on an analogue variable power supply, before the main pass transistor.  Apart from being able to switch the output off electronically, you could get a ground-referenced voltage proportional to output current - very useful for measuring output current using a standard DVM module - which on a variable PSU is otherwise not easy..  Looking at the specs for your IR3314, I think it would work  ok.  I'll look at the others as well.  Are these things expensive?

Hi David

Aside from standard I/O type stuff, we have used the IR part as a form of peak current shutoff on a power supply using the current mirror to drive a comparator.

Never heard about these before, thanks Aubrey.  I can think of a few uses for them apart from the intended automotive ones.

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
