Semtech Releases New Neo-Iso™ Solid State Relay for Fire Alarms and Safety Systems
Offers engineers an enhanced alternative to mechanical relays and opto-MOS
Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors and advanced
algorithms, today announced a new Neo-Iso™ Solid State Relay (SSR) targeted at Internet of Things such as connected and automated
building systems and devices including fire alarms, siren drivers, smoke detectors, laser barriers, sensors for automatic doors,
and safety and intercom systems.

This Neo-Iso SSR is an alternative to mechanical relays and opto-MOS. It offers up to 10 times lower control current and RDSon,
protection from overcurrent including a feedback status pin, a 90% smaller package, and higher robustness because there is no
moving part. The on/off commands are sent with a simple transient‐immune differential clock signal from any microcontroller. The
device also includes integrated 240 mΩ bidirectional load switch allowing AC or polarity free applications up to 36V peak.
“Semtech’s new Neo-Iso solid state relay expands our platform with an enhanced feature set required for Internet of Things (IoT)
such as automated building systems market,” said Francois Ricodeau, Sr. Product Line Manager for Semtech’s Wireless and Sensing
Products Group. “Our new SSR is powered and controlled from a simple clock interface, thus reducing the design-in effort to a
minimum for engineers. We believe Semtech’s Neo-Iso platform will become the standard for multiple systems.”
The new Neo-Iso SSR, TS13501, supports DC and AC systems and is priced at $0.62 in volumes of 10,000 units. For more

About Semtech’s Neo-Iso™ Solid State Relays
Semtech’s Neo-Iso technology is an energy harvesting platform engineered for self-powered control systems. It enhances Internet
of Things applications, such as smart home technology, by adding higher levels of intelligence and control. Our compact Neo-Iso
switches make it possible for low-power microcontrollers to control high voltage loads in a system. Reporting of fault conditions
from the switch to the controller enables system responses resulting in a safer, more efficient operation. Low current draw allows
each switch to operate on power harvested from the load, eliminating the need for additional supplies. These isolated power
switches are designed as a silent operation with low quiescent operating current and a single control panel for on/off input.
