With a footprint 60% smaller than a comparable
circuit built from discrete components, the PWD13F60
can also boost end-application power density. By
integrating four power MOSFETs, it presents a uniquely
efficient alternative to other modules on the market
that are typically dual-FET half-bridge or six-FET three-
phase devices. Unlike either of these choices, only one
PWD13F60 is needed to implement a single-phase full
bridge, leaving no internal MOSFETs unused. There
is also flexibility to configure the module as one full
bridge or two half bridges.
Leveraging ST’s high-voltage BCD6s-Offline fabrication
process, the PWD13F60 integrates gate drivers for
the power MOSFETs and the bootstrap diodes needed
for high-side driving, which simplifies board design
and streamlines assembly by eliminating external
components. The gate drivers are optimized for reliable
switching and low EMI (electromagnetic interference).
The SiP also features cross-conduction protection and
under-voltage lockout, which helps further minimize
footprint while ensuring system safety.
Further attributes of the PWD13F60 include a wide
supply-voltage range, extending down to 6.5V for
maximum flexibility and simplified design. In addition,
the SiP inputs can accept logic signals from 3.3V to 15V
to ensure easy interfacing with microcontrollers (MCUs),
digital signal processors (DSPs), or Hall sensors.
The PWD13F60 is available now, in a thermally efficient
multi-island VFQFPN package, priced from $2.65 for
orders of 1000 pieces.
ams tri-stimulus color sensor provides
precise measurements of biologically
influential blue light
AMS, a leading worldwide supplier of high performance
sensor solutions, today introduced the AS7264N, a tri-
stimulus sensor which provides measurements of color
that closely match the human eye’s response to the
visible light spectrum. The new sensor also accurately
measures blue-light wavelengths, which researchers
have linked to important health effects such as
disruption or management of the circadian rhythm,
accelerated eye aging, and eye strain.
Provided in a compact 4.5mm x 4.7mm x 2.5mm land
grid array (LGA) apertured package, the AS7264N’s
small size makes it well suited for luminaires and
connected sensor packs; it is expected to be used in
emerging applications of human-centric lighting and
smart building control.
The new sensor is based on the successful ams AS72xx
product platform which includes a complete family of
light and color sensors from near-UV to near-IR for
spectral and lighting applications. The family’s tri-
stimulus color sensors use unique on-wafer silicon
interference filters to create individual spectral channels
matching the characteristics of the XYZ standard
observer model as specified by the CIE 1931 standard.
The AS7264N supplements that with two additional
blue light filters, providing the capability to accurately
measure the intensity of blue light at both the 440nm
and 490nm wavelengths.
The small, low-cost, board-mounted AS7264N allows
the implementation of novel light control functions in
luminaires, displays, and smart building automation or
management systems. By incorporating an AS7264N
into their product, lighting and building automation
sensing solution manufacturers are able to deliver real-
time smart color monitoring to measure and respond to
end-users’ exposure to blue light wavelengths.
Like other members of the AS72xx series, the AS7264N
provides easy-to-use digital color measurement outputs
over an I2C interface. The device’s silicon interference
filters, which feature minimal drift over time and
temperature, enable lifetime end-device calibration.
Programmable on-chip LED drivers enable direct control
of synchronized electronic shutter functionality.
“With true color sensing and precise spectral
measurements at wavelengths with active
photobiological influence, the AS7264N serves a
wide range of applications including ambient light
characterization and light exposure data collection
for commercial, residential, and industrial lighting
applications. This solution will help manufacturers get
to market quickly with applications that address the
interaction between light and human health,” said Tom
