PROTECTING
AGAINST THE
DANGERS OF
HIGH-VOLTAGE
SIGNALS
To better protect industrial
systems from the dangers
of high-voltage signals,
equipment designers can now
turn to the new robust and reliable
MAX22445 5kV four-channel
reinforced digital isolator from
Maxim Integrated Products.
Delivering up to two-times greater
throughput at 4x lower power
consumption versus competing
solutions, the MAX22445 provides
reliable communication across
the isolation barrier to ensure safe
operation of compact industrial,
medical and other equipment.
In high-voltage equipment, digital
isolators provide signal isolation and
level-shifting for proper operation of
many circuits, while also protecting
users from dangers such as electric
shock. Yet, not all of these isolators
are alike as many consume a
large amount of power, generate
significant heat and introduce large
propagation delays, limiting system
reliability and throughput.
Overcoming the shortcomings
of other digital isolators, the
MAX22445 delivers reinforced,
dual insulation barrier isolation for
fast digital signals. The IC, which
mitigates the dangers of highvoltage
power, transfers signals of
up to 200Mbps with significantly
less power than competitive
solutions. It is available in a 16-pin
wide-body SOIC package with 8mm
of creepage and clearance.
KEY ADVANTAGES:
• Low power: 0.41mA per channel
current consumption and 0.74mW
power consumption at 1Mbps with
VDD at 1.8V. The IC has 4x lower
power consumption compared
to competing solutions while also
reducing heat generation and
enabling reliable and compact
designs.
• High speed: maximum
propagation delay of 10.5ns and
maximum data rate of 200Mbps
enable fast and accurate data
acquisition and high-speed
interfaces with wide timing
margins. The IC delivers up to twotimes
greater throughput versus
other available solutions.
• Robust and Reliable: dual barriers
of isolation provide 5kVRMS
and 10kV surge for reliable
performance over a long product
lifetime and meet the safety
standards required for operator
protection.
WORKPLACE
HEALTH AND
SAFETY
TRAINING
Good health and
safety practice in the
workplace is not only
a legal requirement, it’s also
fundamental to operating a
good business.
The EMA is an NZQA-registered
private training establishment
(PTE) that provides a
comprehensive range of health
and training programmes
including online courses,
webinars, short courses,
certificate and diplomalevel
courses, seminars and
conferences. It runs training
regularly in Rotorua, Whakatane,
Tauranga, Hamilton, Auckland
(Manukau, Central, West and
North Shore) and Whangarei, or
at your site.
"I do not enjoy courses as a rule,
I often find them boring and
feel talked at and uninvolved.
However, I found the H&S Rep
Stage 1 course informative, fun
and very valuable. The course
was taken by Leon Fox and he
engaged my interest and played
to my learning style. I would
highly recommend the EMA if
you want to get away from hum
drum droll courses and really
benefit and enjoy your learning,”
says Erin from Drake NZ Ltd.
