Circuit Protection – Is Your Data Is Safe When Stored On Branded USB Devices?

Safety Measures Inherent Within Branded USB Devices

In particular, we talked at some length about the superb IndyCar racing season and also the exciting NASA Speed-2-Design development programs that we had spent a lot of time on during the last 24 months.

Car Racing and of course space exploration are, put simply just two excellent and interesting examples of methods that are relevant to the necessity for effective circuit protection. Sophisticated electronics abound in motor car racing, but not just around the cars themselves however, but also to a large extent, in the communications equipment used within the starts and the maintenance areas as well. A lot of that sophisticated equipment is considerably more sensitive than was previously known, since it is based on digital electronics which in themselves, require and need a much greater degree of electronic circuit protection.

It is essential to be certain that the data you store on your branded usb sticks is totally safe from damage by static charge and it is for that reason that most branded usb devices are no longer susceptible to static charge inflicted damage.

A Place For Branded USB Tested in Space Programs

Despite the well-known fact that electrical static shocks may in fact be nothing more than an annoyance in the colder weather to many people in the world, in fact, these sometimes violent electrical discharges can often spell out many real and awkward difficulties for the sometimes critical electronics to be found in orbit, on extraterrestrial missions or in branded usb products.

Regrettably, I have to say, that for several young and very youthful electronic engineers today, the extreme particulars involved in creating sufficient technical electronic circuit protection frequently aren't educated sufficiently in universities, colleges and other establishments. Naturally, this is a serious issue for those manufacturers of the very memory products that eventually find their way into branded usb and other products.

Many graduate engineers care, it would seem, much more about chasing excellent and rewarding careers in product design when it is compared to important technical issues like overcurrent and, of course, static shock immunity measures. If you happen to possess the same, or similar product design mindset but nonetheless understand that the work demands a larger and more in-depth understanding of electronic circuit protection, especially if and when involved in designing similar products as vitally important as branded usb memory some of the more popular features of my recent lecture to Stanford students is merely an introduction.

The Need For Circuit Protection In Branded USB Products

It goes without saying that circuit protection and the components involved in it are highly essential elements in many programs ranging from electronic devices, including branded usb devices, and telecom circuits through to motor vehicles and industrial equipment.

They safeguard electronic products such as branded usb sticks and many other business assets against damage and harm being triggered by short circuits and harmful electrical surges, electrostatic discharges, natural occurrences such as lightning, powerful electrical load switching, as well as many other dangerous electrical phenomena.

Common kinds of circuit protection products for electronic items include the use of thyristors, specialist equipment such as transient current suppression diodes, as well as branded usb and diode arrays, electrical fuses, PSTCs (positive temperature coefficient) products, as well as varistors, certain types of gas discharge tubes (GDTs), and last, but not least,ESD guards.

Designing with Circuit Protection in Mind for Branded USB

The process of designing the right level of circuit protection for a variety of applications is crucial to ensure that harmful items are prevented from reaching the general public. As an example, lithium ion cells, such as those employed in laptop computers and many other devices, are highly susceptible to instances of thermal runaway.

Raising the temperature of a Li-ion battery higher than 140°F results in a hazardous and jeopardized cell which can easiliy be responsible for a power surge and often results in fire. For this reason, batteries used for laptops along with many other portable electronic products where branded usb may be used often contain many different types and levels of protection to ensure safety under virtually all conditions when available to the general public.

These measures start by using the battery cell with a built-in sensor and temperature switch, which is known as a PTC, and which safeguards against unusually high current surges. A circuit interrupt device (CID) which can open the electrical path in the event of an overcharge boosting the interior cell pressure level to at least one,000 kPa (145 psi), in conjunction with a safety vent that will release gas in the event of a rise in battery cell pressure.

This can result in loss of data in branded usb devices. Additionally to those internal safeguards, there are also exterior electronic protection circuit which prevent the charge current associated with a cell exceeding a voltage of 4.3V. as well as this, a fuse cuts the current when the level of the skin temperature associated with a faulty cell gets close to 90°C (194°F).

To avoid the battery cell over-discharging, there is a control circuit which reduces the current path at a level of around 2.2 V/cell.

Getting Priorities Right When Designing Circuits Used In Branded USB

Far too often the circuit protection may end up being the last feature that some electronics engineers will consider, simply because they tend to prioritize the creation of the main functionality of the products as quickly and efficiently as they can.

This is true of branded usb as it is with many other products. However, dealing with circuit protection only as an afterthought has the unfortunate consequence of serious effects.

Consequently, even if the manufacturers and designers do not have to re-design the layout of the board, time pressures could easily cause engineers to choose a less-than-optimal protection device or lead them to place a device in a non-optimal place.which could lead to functional failures as well as poor reliability and issues of safety and outbreaks of fire.

The optimum time to begin considering circuit protection is right at the outset of the design process and prior to starting to design circuit boards. At this time, ESD rankings figures can be found, and circuit engineers and designers can understand how resilient, robust or how sensitive the chips are, especially those used in branded usb products.

Keeping Circuit Protection Standards High for Branded USB

The start of the process should be to know the outcome of all of the relevant safety standards. Standards relating to circuit protection include individuals from Underwriters Labs, Energy Star, NEMA, JEDEC, CSA Group, IEEE, ANSI/NEMA, and standards physiques in Canada as well as Japan, Korea, and of course Europe, alongside very many others including the manufacturers of branded usb products.

Circuit protection manufacturers' websites are great places to search for guidance. Take note that, for example, the Littlefuse Speed-2-Design website is especially targeted at helping time-challenged designers identify circuit protection solutions and those involved in the design of branded usb products should take note.

If you are wondering much more about generation x of circuit protection customers, especially those of you involved with branded usb technologies, begin to see the slideshow of my recent Stanford presentation around the Speed-2-Design information website.
