Semtech New Isolated Power Switch Platform Provides Control for Home Automation, Connected Buildings and Internet of Things Applications

Intelligent Neo-Iso™ platform offers the right solution for IoT
applications with superior system flexibility, providing galvanic
isolation and intelligent switching capabilities

(Nasdaq: SMTC),
a leading supplier of analog and mixed-signal semiconductors, today
announced the expansion of its revolutionary Neo-Iso™
Isolated Power Switch Platform
with the addition of the TS13101,
a new galvanic isolated intelligent power switch. The TS13101 is
optimized for compact Internet of Things (IoT) low-voltage applications
such as smart thermostats, security, intelligent sensor control and
other home automation systems. Other Neo-Iso offerings can control power
line voltages for smart plug, light switch and industrial applications.

The intelligence in the TS13101 provides fault and diagnostic data to
the microcontroller, enabling more robust systems with a self-diagnostic
capability. The Neo-Iso™ family of products comprises a series of
intelligent power switches that control resistive and inductive loads
while protecting sensitive system circuitry from voltage surges and
transients. They replace components such as electromechanical relays
(EMRs) in these applications, deliver a faster turn on/off time of 25
microseconds, and provide a field-tested life cycle that is orders of
magnitude higher than existing electromechanical technologies. Ultra-low
primary current in the range of 5-10 microamps allows the system to
power itself by tapping energy from the load, avoiding the need for a
secondary power source.

The family of devices is controlled by the system microcontroller using
standard general-purpose input/output (GPIO) pins. This switch solution
isolates the microcontroller from the load that is being switched with
scalable isolation voltages between 100V to 10kV.

The TS13101 is a galvanically isolated 60V power switch device with
bi-directional blocking, packaged in a 4mm x 4mm QFN with a height of
just 0.8 mm, which is significantly smaller than bulky EMRs and enables
the design of thin and compact IoT applications. The TS13101 operates
silently without the clicking sound that is present with an EMR.

“These new isolated switches deliver intelligence, capability and
reliability beyond existing, less advanced solutions. They are designed
to deliver the features required for emerging home automation systems
while helping these products maintain a high-tech aesthetic through
their slim size and silent operation,” said Ken Moore, Vice President
and General Manager of Semtech’s Triune Product Group. “Our breakthrough
Neo-Iso™ technology enables our customers to design smarter, more
functional and more reliable IoT products by utilizing a cost-effective,
standard semiconductor process technology to solve challenging size and
system constraints.”

Key Features of the TS13101

  • Low quiescent operating currents; 2µA in OFF state and 4µA in ON state
  • Scalable galvanic isolation from primary to secondary sides of the
  • Operation from 2.9V to 5.5V compatible with standard microcontrollers
  • 60V switch, with up to 4A operating current
  • Real-time diagnostic and fault information

Pricing and Availability

The TS13101 (order code: TS13101-QFNR) is available immediately in
production quantities and is currently priced at $0.83 each in
1,000-piece lots. Semtech offers comprehensive design assistance,
including field- and factory-based support. Data sheets, volume pricing,
