Secure supervisor circuit incorporates tamper detection
Articles 8/29/2007 Post a comment
Maxim says the SPI-compatible DS3650 is the industry's first secure supervisor with tamper detection to meet the payment card industry's voltage- and temperature-monitoring requirements. It integrates a battery-backup controller, system power monitor, CPU supervisor, temperature sensor, along with two tamper-detection comparators.

4-channel LIN transceiver reduces system costs
Articles 8/16/2007 Post a comment
LIN nodes continue their exponential growth rates in cars resulting in master modules controlling multiple LIN busses. To address this growing need for multi LIN transceiver systems Melexis introduces a 4-channel LIN transceiver IC.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
