Overview
IEC TS 60747-19-2:2021 is an internationally recognized technical specification developed by the International Electrotechnical Commission (IEC). It addresses semiconductor devices, specifically smart sensors and their application within low-power smart sensing units. This standard provides essential guidelines for the indication of specifications for both sensors and the power supplies that drive them, enabling effective low-power operation and supporting the growing integration of smart sensing technologies in various industries.
The specification defines best practices for describing current consumption characteristics of low-power sensors, the role of autonomous power supplies (such as batteries and energy harvesters), and the clear identification of power supply specifications in smart sensing systems. By following these guidelines, designers can more easily select and combine the key components of a smart sensing unit: smart sensor, terminal module, and power supply. This approach facilitates the development of efficient, flexible, and interoperable systems, especially relevant in IoT and industrial automation contexts.
Key Topics
-
Smart Sensing Unit Composition
- Identifies the three critical components: smart sensor, terminal module, and power supply.
- Describes how these components collaborate for wireless data transmission and autonomous operation.
-
Specification Indication for Low-Power Sensors
- Guides on documenting detailed power consumption profiles and time-variation characteristics.
- Emphasizes the need to report sensor operation in different conditions (e.g., typical vs. worst-case voltage and temperature).
- Recommends inclusion of under voltage lock out (UVLO) circuitry information in datasheets.
-
Power Supply Specification Guidelines
- Outlines required data for datasheets, such as supply power capability, output voltage ranges, maximum supply current, leakage current, and temperature dependence.
- Highlights the importance of indicating additional features (e.g., ripple, output impedance, charge/discharge cycles, and signal lines for power-good or remaining charge indicators).
-
Design Facilitation and Interoperability
- Encourages standardized specification reporting to streamline component selection and promote interoperability in smart sensor networks.
Applications
IEC TS 60747-19-2:2021 is highly relevant for applications where low power operation and modularity are critical:
