The BTS5016SDA is a one channel high-side power switch in PG-TO252-5-11 package providing embedded
protective functions.
The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on
Smart SIPMOS chip on chip technology.
The BTS5016SDA has a current controlled input and offers a diagnostic feedback with load current sense and a
defined fault signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown.
Wireless means different things to different people. For this book, it refers
to the radio systems that provide point-to-point, point-to-multipoint, and
Earth-space communications over transmission links that propagate outside
buildings through the lower atmosphere. Wireless systems are being built
that provide data transmission between computers and other devices on
one’s own desk. These are part of the wireless world but not the part where,
except for interference perhaps, the atmosphere has any influence. The intent
of this book is to provide a description of the physical phenomena that can
affect propagation through the atmosphere, present sample measurements
and statistics, and provide models that system designers can use to calculate
their link budgets and estimate the limitations the atmosphere may place on
their design.
In 2001, Orange, a UK mobile network operator, announced the “Orange
at Home” project, a smart house incorporating the latest technology
wizardry built some 20 miles north of London. It was intended to be more
than a mere showcase, with plans for real families to move in and live
with the smart home. My then research establishment, the Digital World
Research Centre at the University of Surrey, was commissioned to study
how these families reacted to their new home, and to report lessons for
the future development of smart homes and smart home technologies.
Electricity has been chosen as the most convenient and useful form of energy, due
to its ease of transportation over large distances and easy conversion to other
energy forms. The biggest inconvenience with electricity is that it cannot be stored
and must be utilized at the moment of generation. The storage of a large amount of
electrical energy is usually connected with its conversion to other types of energy,
which significantly reduces the efficiency of such processes. The aim of the power
system, often treated as the biggest and the most complex machine ever built, is to
deliver uninterruptible electric energy of demanded quality parameters to
consumers.
For many years prior to the 1970s, engineers designed and built switch mode
power supplies (SMPSs) using methods based largely on intuitive and exper-
imentally derived techniques. In general, these power supplies were able to
achieve their primary goal of high-efficiency power conversion; unfortu-
nately, due to the lack of adequate theoretical analysis techniques, many of
these power supplies only marginally met their desired performance require-
ments. In many cases, they were considered to be unreliable.
I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I
had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end
requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95!
Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and
think of all the possibilities built into that piece of hardware. I am amazed by what has happened to
everything from toasters to car engines. Who-da-thunk-it 40 years ago?
In the early days, embedded systems were built primarily by engineers in a
pretty exclusive club. Embedded devices and software tools were expensive,
and building a functional prototype required significant software engineering
and electrical engineering experience.
Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world
application. This combination makes Arduino a perfect environment for school students, seasoned developers, and
designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by
developers in a more advanced setting. Going beyond projects, this book provides examples that demonstrate concepts
that can be easily integrated into many different projects and provide inspiration for future ones. The focus of this book
is as a transition from the intermediate to the professional.
可測試性設計(Design-For-Testability,DFT)已經成為芯片設計中不可或缺的重要組成部分。它通過在芯片的邏輯設計中加入測試邏輯提高芯片的可測試性。在高性能通用 CPU 的設計中,可測試性設計技術得到了廣泛的應用。本文結合幾款流行的 CPU,綜述了可應用于通用 CPU 等高性能芯片設計中的各種可測試性方法,包括掃描設計(Scan Design),內建自測試(Built-In Self-Test,BIST),測試點插入(Test Point Insertion),與 IEEE 1149.1標準兼容的邊界掃描設計(Boundary Scan Design,BSD)等技術。
