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

Semtech TS13101

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

Semtech Corporation 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.

Semtech - TS13101

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 100 V to 10 kV.

The TS13101 is a galvanically isolated 60 V power switch device with bi-directional blocking, packaged in a 4 mm × 4 mm 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.
