Airbag System Basis Chip (SBC) with PSI5

The automotive industries are now into electronics applications in which embedded systems are already part of its major components. In this design, it features the Peripheral Sensor Interface 5 (PSI5), which is the most efficient standard interface of sensors and electronic control units in automotive. It supports complete airbag system that includes system power mode control, supplies for squib firing, satellite sensors, and local Electronic Control Unit (ECU) sensors and ECU logic circuits. It has dedicated safing state machine that complements the airbag’s MCU hardware/software safing approach. The system itself is capable of diagnostics and self-protection.

The design is comprised of MCZ33789 Freescale airbag system basis chip that manages the entire airbag partitions and some major components like squib driver IC, SPI communications with MCU, accelerometer sensor, satellite sensors, and dc sensors for monitoring. The squib driver IC supports air bag modules and seat belt retention that functions with accelerometer sensor. The MCU provide the connection of airbag system with the entire electronic applications of the vehicle. The LC filters are provided to ensure frequency range.

The design is used in different airbag system in which it optimizes the capability of providing safety to users. It can be used for further development of safety system in automotive and other vehicle that is prone to crash or collisions. It can help save lives during accidents.

Jameco Electronics Hobbyist Study: Electronics Skills Are Critical to Fueling American Economy

electronics-hobbiest-1306121638_500_178

BELMONT, Calif.–(BUSINESS WIRE)–A comprehensive study of electronics hobbyists released today found that over 68% of hobbyists believe electronics as a hobby is essential to fueling the American economy. Over 1700 electronics hobbyists participated in the study, the Great American Electronics Hobbyist Census, conducted by electronic component distributor, Jameco Electronics.

In 2014, electronic component shipments in the United States grew to 4.9% according to the Commerce Department—well ahead of the growth of the overall economy. Participants cited component availability and affordability as a driving factor behind future growth in the hobby.

“By all measures, the electronics hobby is booming,” said Greg Harris, Jameco Vice President of Marketing. “Our study found an underlying passion for electronics that builds the kinds of skills that make the American economy strong.” Serious electronics enthusiasts expect growth of the hobby to continue. More than half of the study respondents state they plan to increase the amount of electronics projects they complete over the next five years.

Short circuit protection for (almost) any power supply

FZYG9SOIAEJKDQ1.MEDIUM

by TrichogasterAzul @ instructables.com:

This instructable is about a universal short circuit protection that I’ve designed to use in bench power supplies. I’ve designed it to fit in most power supplies circuits. In order to this circuit fit in your bench power supply, you will need to do some calculations, but don’t worry, I’ll explain everything on the next steps.

The CANable: a small USB to CAN adapter

Ethan of Protofusion writes:

The CANable is a hardware clone of Eric Evenchick’s CANtact project, an open-hardware USB to CAN adapter compatible with socketcan. I took his design and reworked the hardware to be a bit more suitable for my personal needs, with a screw terminal instead of a DB9 connector and a much smaller PCB.

In LESSON 18 you learned how to use an ultrasonic sensor to measure distance, and in LESSON 19 you learned how to connect an LCD to the arduino. In this lesson we will combine what you have learned to create a circuit for measuring distance, and displaying results on an LCD display.

You can use the schematic below to connect the circuit. If you did LESSON 19, you should already have the LCD hooked up. For more info on connecting to the LCD, and how it works, review LESSON 19. This schematic is for the LCD in the Sparkfun Inventor Kit, or similar LCD. If you have a different LCD, you will have to determine the proper connections. There are some helps in LESSON 19. If you need the ultrasonic sensor, you can pick one up HERE.

Superthin Supercapacitors

GW134T_Frontby elektormagazine.com:

CAP-XX have introduced a range of flat single-cell supercapacitors targeted at small (or disposable) devices for IoT applications. This new Thinline range boasts the world’s thinnest supercap at 0.6 mm thick. CAP-XX use a unique nanotechnology construction that stores electrical charge in engineered carbon electrodes on aluminium foil to minimize resistance and maximize capacitance. This type of electrode construction packs the highest energy and power densities possible into thin, prismatic packages.

The idea was born while working with a customer designing a disposable insulin pump. “We figured out how to eliminate materials and change some processes to reduce costs and thickness,” explained Anthony Kongats, CAP-XX CEO.

LT8616 – Dual 42V Synchronous Monolithic Step-Down Regulator with 6.5μA Quiescent Current

 

8616

The LT8616 is a high efficiency dual synchronous monolithic step-down switching regulator with an input voltage range of 3.4V to 42V. Its dual channel design delivers independent 2.5A and 1.5A continuous current to outputs as low as 0.8V. A dual channel synchronous rectification topology delivers up to 95% efficiency while Burst Mode operation keeps quiescent current under 6.5μA (both channels enabled) in no-load standby conditions, making it ideal for always-on systems. Switching frequency can be programmed from 200kHz to 3MHz and is synchronizable throughout this range. The LT8616’s 35ns minimum on-time enables 16V to 1.8V step-down conversions, while switching at 2MHz helps designers avoid critical noise-sensitive frequency bands, such as AM radio while having a very compact solution footprint.
