This presentation goes through some of the common challenges for a high cell count battery pack, and shows you how the BQ40z80 can help with these challenges. I’m going to start off with highlighting some of the changes between the BQ40z50 and the BQ40z80. Next, I’ll go into the tools we have in place for the BQ40z80 to evaluate the device, as well as start configuring the dataflash…

The personal electronics industry is the driving force behind what features consumers want to see in their vehicles. Automakers are left designing for these personal electronics but must cater to specific automotive needs. Additionally, automakers must keep up with new technology trends including Type-CTM, USB legacy, USB On-the-GoTM and the challenges these present in the automotive system. This…

In this video we will review the reverse battery protection stage of the automotive frond-end power stage. To protect the downstream circuits from negative polarity resulting from accidental reverse connection of battery terminals different methods are used.
