The new Neo-Iso SSR is targeted at 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. Offered as an alternative to mechanical relays and opto-MOS, it features up to ten times lower control current and RDSon, protection from overcurrent, including a feedback status pin, a 90% smaller package, and higher robustness.
On/off commands are sent via a transient-immune differential clock signal from any microcontroller. The device also includes integrated an 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," says 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.
