Key features and benefits of the ISOW7841
Eighty percent higher efficiency: With the industry’s
lowest power consumption, the ISOW7841 reduces
device operating temperature by up to 40 degrees C,
enabling higher power delivery, higher channel count and
longer system lifetime than other integrated solutions.
Single-chip reinforced isolated power and data up to
100 Mbps: Combining reinforced isolation and DC/
DC conversion in a single package minimizes board
space and cost for easier multichannel system design.
A working voltage of 1 kVrms helps provide improved
system reliability and lifetime. The ISOW7841 supports
an input voltage range of 3V to 5.5V, while delivering an
industry best 0.65W of output power.
More than 10-dB lower radiated emissions: The
ISOW7841 improves system signal integrity by
minimizing system noise and providing robust
electromagnetic compatibility to meet International
Electrotechnical Commission (IEC) 61000-4-x standards
for electrostatic discharge and electrical fast transient
events. Additionally, the reinforced isolator offers the
highest level of immunity available in the market today
reducing the effect of noise and high-voltage events on
the industrial equipment.
The ISOW7841 reinforced isolator with a three forward/
one backward channel configuration is the first device
in the ISOW78xx family, with multiple devices expected
later in 2017. These new devices join TI’s isolation
portfolio that supports the highest isolation ratings,
reliability, immunity and performance.
Tools and support to speed design
Designers can quickly and easily evaluate the new
reinforced isolator with the ISOW7841 evaluationmodule
(ISOW7841EVM), available today for US$49 from the
TI store and authorized distributors. Engineers can
also jump-start their system design with the integrated
signal and power reference designs for isolated RS-
485 and RS-232. Additionally, another reference design
is available to help integrate reinforced isolation and
power in an industrial grid design.
Package, availability and pricing
The ISOW7841 reinforced isolator with integrated power
is now available through the TI store and authorized
distributors in a 16-pin small outline integrated circuit
(SOIC) wide-body package. This device is available
in both fail-safe low and fail-safe high configurations.
Pricing starts at US$5.50 in 1,000-unit quantities.

Vishay Intertechnology High Speed PIN
Photodiode Delivers Precise Signal Detection,
Enables Slim Sensor Designs for Wearables
Device Offers Enhanced Sensitivity for Visible Light in 5 mm
by 4 mm SMD Package With Low 0.9 mm Profile
Vishay Intertechnology, Inc. (NYSE: VSH) today broadens its
optoelectronics portfolio with the introduction of a new high
speed silicon PIN photodiode with enhanced sensitivity for
visible light. Offered in a compact 5 mm by 4 mm top-view,
surface-mount package with a low 0.9 mm profile, the Vishay
Semiconductors VEMD5080X01 offers fast switching times
and low capacitance for precise signal detection in wearable
devices and medical, industrial, and automotive applications.
Offering a large radiant-sensitive area measuring 7.5 mm²
— and high radiant sensitivity with a reverse light current
of 45 µA and dark current of 0.2 nA — the device released
today detects visible and near infrared radiation over a wide
sensitivity range from 350 nm to 1100 nm. For green LEDs, the
VEMD5080X01’s sensitivity represents a 30 % improvement
over previous-generation solutions.
When used with Vishay’s VLMTG1400 green LED, the
photodiode’s small size and sensitivity enable slim sensor
designs for optical heart rate detection in wearable devices
such as fitness trackers and smart watches. When combined
