Hello,
According what I've read in Bob Zollo's article, below, my free-with-purchase Harbor Freight DMM is not going to do any good in evaluating battery cell self-discharge, or for other measurements for that matter. Bob dives into the details of what kind of resolution and accuracy is needed in order to characterize today's battery cells.
Lee brings us a brief overview of ST Micro's latest AEC-Q100-qualified power-management IC (PMIC) for automotive applications. With programmable outputs of 5V, 3.3V, or 1.2V at currents up to 1A, its direct from battery buck converter coupled with other processor and housekeeping/PMIC stuff makes it a nice candidate for functional safety applications, given it's approved for use up to ASIL B.
Contributing author Jared Becker, from TI, shows us how a series of power FETs can be used to design a discrete e-fuse that provides short-to-ground and short-to-battery protection.
If you have an area of subject matter expertise you'd like to share with our worldwide readers, please shoot me an email with a paragraph or two about what you'd like to write about. Needs to be technical in content - no fluffy marketing/sales stuff. That is paid-for ad stuff on the other side of the firewall from our editing team.
And, lastly, you've seen me mention "sister publications" in some of my prior Automotive Electronics newsletters. So, we've put together a page containing links to a few of Electronic Design's siblings in the EndeavorB2B family that you may find useful.
enjoy,
