Semtech’s Neo-Iso™ Platform Supports High Load Current HVAC and Industrial Applications

With proven capabilities in the residential industry, the new Neo-Iso IC offers flexibility and options for maximum current selection

Camarillo, California - August 21, 2017 -

Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced the availability of its new capabilities to the Neo-Iso™ platform of solid state relays. The solid state relay expands the company’s Neo-Iso platform by supporting commercial heating, ventilation and air conditioning applications (HVAC) that need flexibility and options for commercial and industrial high load-currents.

For commercial applications that are equipped with large three-phase contactors, such as commercial HVAC applications, the new Neo-Iso solid state relay is specifically designed to handle configurable inrush and steady state current limits. Compared to residential applications (i.e. smart thermostats, alarm panels, etc.), the three-phase contactors are heavier to close and can generate as much as 10A of inrush current, which the new Neo-Iso platform is specifically designed to handle.

 “Semtech’s Neo-Iso platform is now expanding beyond the home, with high growth in industrial and commercial applications,” said Francois Ricodeau, Product Line Manager for Semtech’s Power and High-Reliability Products Group. “The new Neo-Iso platform offers advanced features for designers that need support for industrial high load-current applications for HVAC installations.”

Key Features of the New Neo-Iso Solid State Relay

• External FETs offer flexibility and options for maximum current selection

• Configurable inrush and steady state current limits

• Analog to digital converter with current, voltage and temperature measurements to widely expand diagnostic capabilities

• Low quiescent operating currents o 15μA in ON state o 2mA during measurement requests

• Switch to controller scalable galvanic isolation

• Single control signal for input commands

• Microcontroller-compatible levels

• Bi-directional blocking in OFF state

Pricing and Availability

The Neo-Iso solid state relay (SKU: TS13401) is available immediately in production quantities and are priced at $0.90 each in 1,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support. Datasheets, volume pricing, and delivery quotes, as well as evaluation kits and samples, are available at
