Compact overvoltage, undervoltage, reverse protection with LTC4365

There are many circuit simulators available which are based on the original SPICE (Simulation Program with Integrated Circuit Emphasis) code developed at Berkley university at the end of ’60. Linear Technology developed their own version called LTSPICE IV very useful when you need to simulate circuits which use components made by LT. LTSPICE IV can be downloaded free of charge from http://ltspice.linear.com/software/LTspiceIV.exe. Let’s see how is possible to design a very fast overvoltage, undervoltage and reverse protection using few components (the pictures have been extracted from the official datasheet available at http://cds.linear.com/docs/Datasheet/4365f.pdf and from LTSPICE IV available at http://www.linear.com/designtools/software/#LTspice):

The italian way to be makers

MakersItaly, the three days fair dedicated to the new concept of making, has closed sunday evening: the italian community of makers is growing and is healty. Many people, mainly makers as well as curious, visited this very important fair for the italian DIY movement. The slogan of the fair was “don’t be bored……. do something!” which well represent the spirit of the italian makers who was there. Every day all around the world analysts are more convinced about the importance of the innovation and the new business models of this revolution which can be a great opportunity for the ones who want to use their own skills to trasform the passion in business. Not everyone can or is interested in turning this passion into an advantageous business; anyway these skills are definitely a good way to spread knowledge. Words cannot be explicit like the pictures, so we want to show you the most important things we seen at makersItaly through our pictures: Continue reading

STM32 F0 DISCOVERY

STM32 F0 DISCOVERY is a low-cost and easy-to-use development kit to quickly evaluate and start to develop with STM32 F0  microcontroller family. It is sold in a simple plastic package: there is no material to give protection against electrostatic discharge, no accessories like usb cable or user manual but only a prototype board to help you during applications development as you can see below:
