Analogue front-end ICs ideal for
power measurement
Microchip has released two new Analogue
Front End (AFE) ICs for single-phase meters
and power monitors. The new MCP3919
integrates three, and the MCP3912 four,
channels of 24-bit, delta-sigma analogue-to-
digital conversion. They offer very high
accuracy, including -107dB total harmonic
distortion, for precise signal acquisition.
The new AFEs also include a low-drift
voltage reference, programmable gain
amplifiers, phase-delay compensation and
cyclic redundancy check.
APPLICATIONS
Cypress Semiconductor has introduced
a highly integrated Bluetooth
®
Low
Energy (BLE) Programmable System-
on-Chip (PSoC) which simplifies the
design of low-power, sensor-based
systems for the Internet of Things.
The PSoC 4 BLE integrates a Bluetooth Smart
radio, a 32-bit ARM
®
Cortex
®
-M0 core with low-
power modes, programmable analogue blocks,
and Cypress’s proven CapSense
®
capacitive
touch-sense controller. PSoC 4 BLE also
integrates an on-chip balun which simplifies
antenna design while reducing board size and
system cost.
This enables the creation of Bluetooth Smart
products that benefit from long battery life,
customisable sensing capabilities, and a sleek,
intuitive user interface.
In addition, Cypress provides a streamlined
development environment that helps to
accelerate the process of integrating Bluetooth
Low Energy capability into end-product
designs. Cypress has simplified the Bluetooth
Low Energy protocol stack and profile
configuration into a new royalty-free, GUI-based
‘BLE Component’. This is an embedded IC
within PSoC represented by an icon which can
be dragged and dropped into designs using
Cypress’s PSoC Creator

Environment (IDE).
Alternatively, users of Eclipse

or other ARM-
based tools can customise their own Bluetooth
Low Energy solutions on PSoC Creator and
export the design to their preferred IDE.

Cross-reference tool for power ICs
Intersil has released a new power cross-
reference utility which enables designers to
take a bill of materials containing power-
management parts and quickly generate a
list of comparable Intersil parts.
The tool compares the parametric data of
competitors’ devices with the parametric
data of Intersil devices, and presents a
logically sorted list showing a list of Intersil
devices that perform the same basic
function. It also highlights each parameter
on the corresponding Intersil devices,
classifying them as ‘as good’, ‘better’, ‘near
spec’ or ‘outside spec’.

2.4GHz RF amplifier offers low noise and high linearity
NXP SEMICONDUCTORS
NXP Semiconductors has announced
the introduction of the BGU7075, an
analogue-controlled, variable-gain
amplifier module.
Offering both low noise and high linearity, it is
ideal for use in the sensitive receivers found in
mobile telephone network basestations.
The BGU7075 may be used to amplify RF
signals at frequencies between 2,305MHz and
2,570MHz. It has a gain-control range of more
than 35dB, and at its maximum gain, its noise
figure is 1.12dB. The gain is analogue-
controlled, configured so that maximum gain is
at 0V and minimum gain is at 3.3V.
In addition, the internal low-noise amplifier has
two gain settings, which serves to extend the
device’s dynamic range.
Circuit design with the BGU7075 is simple
because it is internally matched to 50Ω, which
means that no external matching is required.
It is housed in a 16-pin, 8mm x 8mm x
1.3mm leadless HLQFN16R package in a
SOT1301 outline.

TVS diode arrays offer 60% lower clamping voltages
than other technologies
LITTELFUSE
Littelfuse has introduced the
unidirectional SPHV and bi-directional
SPHV-C series of 200W discrete
Transient Voltage Suppression (TVS)
diode arrays. The devices are assembled
in a SOD882 (0402) package.
The SPHV and SPHV-C series can absorb
repetitive ESD strikes above the maximum level
of the IEC 61000-4-2 international standard
without performance degradation, and can
safely dissipate up to 8A of induced surge
current.
In addition, their low dynamic resistance
results in up to 60% lower clamping voltages
compared to alternative suppression
technologies, making them ideal for the
protection of modern electronics systems
populated with small-geometry ICs.
The SPHV and SPHV-C are well suited to
the replacement of 0402-sized multi-layer
varistors. They are also excellent solutions for
designers who need to distribute ESD
protection devices around a circuit board.
Littelfuse’s SPHV series replaces 0402 varistors
Made with silicon diodes, the SPHV and
SPHV-C arrays have no inherent wear-out
factor. They support the implementation of highly
robust product designs which are subject to
the constant threat of ESD and which must be
capable of withstanding hundreds or thousands
of ESD strikes over the product lifetime.

MOSFETs combine Schottky-like performance with
low leakage current
NXP SEMICONDUCTORS
NXP Semiconductors has introduced
three NextPowerS3 devices, the first
power MOSFETs to offer a combination
of the performance benefits of an
integrated Schottky diode with low
leakage current.
The devices incorporate
NXP’s unique ‘SchottkyPlus’
technology which provides
the soft switching
characteristics of a Schottky
diode while constraining the
high leakage current which is
associated with conventional
Schottky diodes. In fact,
leakage current in the new
NextPowerS3 MOSFETs has
been reduced to less than
1µA at a 25°C junction
temperature.
The PSMN0R9-30YLD is a
30V MOSFET featuring
on-resistance rated at 0.87mΩ.
NextPowerS3: highly efficient switching operations
The PSMN1R0-40YLD and PSMN1R4-40YLD
are rated for 40V and have on-resistance
values of 1.1mΩ and 1.4mΩ respectively.
The NextPowerS3 MOSFETs are also
notable for their low gate-charge values, which
mean that their switching operation is highly
efficient, a feature that is of particular value at
high frequencies.
Optimised for use as a 4.5V gate driver, the
MOSFETs generate little spiking and ringing,
helping designers to achieve low levels of EMI
in switching power-supply designs.
