Smart-metering ICs gain PRIME
v1.4 certification
Atmel has announced it is the first
semiconductor manufacturer to receive
PoweRline Intelligent Metering Evolution
(PRIME) v1.4 Profile 2 certification. The
certification has been granted to the Atmel
®
|
SMART SAM4CP16B and ATPL230A smart-
metering solutions.
This latest PRIME standard supports
some of the most demanding requirements
of smart-metering systems by offering
increased robustness, throughput, band
expansion and band-plan flexibility as well
as support for the IPv6 protocol.
The reference design is offered
together with a complete
ecosystem to support
customers in building their
applications, including the
STEVAL-ISB027V1 board, API
libraries, and documentation to
support the development of
custom software, as well as a
comprehensive graphical user
interface for monitoring real-
time performance and
diagnostics.
STMicroelectronics has introduced an
integrated digital power controller for
wireless battery-charger transmitters,
offering a flexible and efficient solution
for controlling power transfer to
battery-powered devices that use
electromagnetic induction for recharging.
The new STWBC is certified as compliant with
the Qi 1.1.2 A11 standard of the Qi Wireless
Power Consortium. It is also fully compatible
with the wireless charging protocols specified
by the Power Matters Alliance.
The STWBC, which features an internal
96MHz clock and which supports both half-
bridge and full-bridge topologies, performs all
the functions of transmitter control: it is able to
precisely control the amount of transmitted
power to match the requirements of the
receiving unit while maximising the efficiency of
the power transfer.
The STWBC comes with firmware options,
enabling designers to tailor operation to the
requirements of their end-product without
involving an external microcontroller.
The operation of a Qi 1.1.2 A11-certified
solution based on the STWBC is demonstrated
in the STEVAL-ISB027V1 reference design from
ST, intended for all Qi-compatible receivers. In
the reference design, the STWBC provides for
foreign object detection: the digital feedback
between the transmitter and receiver allows the
detection of metal objects close to the receiver
that could cause a potential hazard, enabling
the STWBC to stop power transmission when
such objects are detected.

New controller enables single-stage buck-converter designs for
very high input:output ratios
INTERSIL
The new ISL8117, a 60V synchronous
buck controller from Intersil, provides a
simple, low-cost and efficient way to
implement a Point-of-Load (PoL) power
supply in which there is a large difference
between the input and output voltages.
The ISL8117 can provide stable operation with
a remarkably low on-time of as little as 40ns.
This enables the designer to create a power
supply with a very low duty cycle,
such as a PoL circuit which steps a
48V input down to a 1V output.
Before now, the designer of such
an application would have to choose
one of two options: an expensive
module, or a two-stage discrete DC-
DC converter circuit. The ISL8117
enables this wide voltage gap to be
bridged for the first time by a single-
stage converter design. This is
cheaper than a module, and both
cheaper and easier to design than
an equivalent two-stage design.
In addition, the ISL8117 provides
high efficiency across all loads. Its
unique diode emulation mode dramatically
lowers light load power consumption while
producing consistent output ripple at varying
load levels.
In ideal situations, a complete power-supply
circuit can be designed with the ISL8117 and
just 10 external components.
The device uses internal loop compensation,
and provides single-resistor settings for
functions such as operating frequency and
over-current protection. Its current-mode
control scheme with input-voltage feed-forward
enables it to support various applications even
with fixed internal compensation schemes.

Ultra-sensitive capacitive touch sensors detect
a gloved finger
ON SEMICONDUCTOR
ON Semiconductor has introduced a
family of capacitive touch-sense
controllers offering either 8 or 16
sensing channels.
The LC717A00AJ and LC717A00AR have 8
input channels for capacitive sensing. The
LC717A10AJ, LC717A10AR and
LC717A10PJ have 16 channels.
The devices are high-performance,
low-cost capacitance-to-digital
converters which may be used to
easily implement an electrostatic
capacitive touch sensor. Extremely
sensitive, they are capable of detecting
tiny changes in capacitance, making
them suitable for use in systems
operated by users wearing gloves, or
through a thick overlay.
The built-in logic circuit detects the
on/off state of each input, and
produces the result as a digital output.
No external components are required for the
measurement function.
Calibration is automatically performed by the
logic circuit at start-up or whenever there are
changes in the operating environment. In
addition, once the operating parameters, such
as gain, are configured, the LC717Ax0
converters can operate in stand-alone mode
when the recommended switch pattern is
applied.
Alternatively, the parameters can be modified
by an external controller via the device’s I
2
C or
SPI bus interfaces.

20V N-channel MOSFET offers
fast switching performance
NXP SEMICONDUCTORS
The PMZ130UNE from NXP
Semiconductors is an N-channel
enhancement-mode Trench MOSFET
rated for a maximum drain-source
voltage of 20V.
The device is notable for its very fast switching:
typical rise time is 12ns, and fall time is just 5ns.
At just 0.7V, the typical gate-source
threshold voltage is also low for a device of this
type. The maximum continuous drain current is
1.8A at 4.5V and an ambient temperature of
25°C. When this ambient temperature rises to
100°C, the maximum allowable drain current
falls to 1.2A.
Heat dissipation is also handled well by the
PMZ130UNE: thermal resistance from the
junction to the solder point is typically 17K/W.
The PMZ130UNE is housed in a leadless ultra-
small DFN1006-3, SOT883 surface-mount
plastic package measuring 1.0mm × 0.6mm ×
0.48mm.

Synchronous buck regulator in tiny 3mm
x 4mm package handles inputs up to 70V
MICREL
Micrel has released a family of high-
voltage synchronous step-down
switching regulators with integrated
power switches capable of providing up
to 4A output current from inputs as high
as 70V.
The MIC28511, MIC28512 and
MIC28513 are
offered in both
Hyper Speed
Control
™
and
HyperLight Load
®
architectures: these
allow for low output-
voltage operation
from a high input
voltage, and offer very
fast response to
transient voltages.
The HyperLight Load
technology also provides very good light-load
efficiency, and requires only a small amount of
output capacitance.
Considering the MIC2851x devices’ high-
voltage capability, they are housed in unusually
small 24-pin 3mm x 4mm QFN packages.
Integrating Micrel's high-voltage buck controller,
which has a wide input-voltage range, with its
FETZilla
™
power MOSFETs and advanced
packaging technology, the MIC2851x
regulators benefit from outstanding thermal
performance. This enables users of the parts to
achieve very high power density, saving board
space, heat-sink cost and cooling energy.
The regulators’ high-voltage capability is
ideal for products which must perform in harsh
environments and for
applications in which the
system is subject to
high-voltage spikes or
high ambient
temperatures. The
MIC2851x family
can withstand
these voltage
spikes without
compromising
efficiency and
thermal performance.
The MIC2851x offers an adjustable output
voltage as low as 0.8V with a guaranteed
accuracy of ±1%. A constant switching
frequency can be selected in a range between
200kHz and 680kHz. This allows the designer
to choose between a higher frequency for a
smaller inductor, or operating at higher
efficiency at a lower switching frequency.

TVS diode array offers 10% lower clamping voltage
for superior protection
LITTELFUSE
The Littelfuse SM24CANA 200W TVS
diode array provides superior
protection against damage due to
lightning-induced transients or ESD in
industrial systems connected by CAN
bus, RS-232 or RS-485 interfaces.
A single SM24CANA array protects both CAN
signal lines. It absorbs repetitive ESD strikes
above the maximum level specified in the
IEC 61000-4-2 international standard without
performance degradation, and safely
dissipates 3A of surge current with very low
clamping voltages. The low typical dynamic
resistance of 0.7Ω results in a 10% reduction
in clamping voltage compared to similar
solutions available in the market, delivering
superior protection to extend the life of
mission-critical equipment.
The SM24CANA provides protection in
accordance with IEC 61000 standards for ESD,
SM24CANA: single device protects dual CAN signal lines
Electrical Fast Transient (EFT) and lightning
protection. Meeting all the requirements of the
rigorous AEC-Q101 qualification regime, it can
also be used in automotive applications such
as drive-by-wire systems, engine-control
modules, powertrain electronics, anti-lock
brakes, airbags and other safety circuits.
In addition, low capacitance of 11pF helps
to preserve signal integrity thereby minimising
data loss.
