Rutronik UK adds Infineon’s coreless open loop current sensor for industrial use
Described as precise and stable, Xensiv TL14971 is Infineon’s industrial, coreless open loop current sensor for industrial applications. The sensor measures from ±25 to ±120A and has individually programmable parameters such as current range, over-current threshold and output mode.
It also has a differential measuring principle, enabling the sensor to suppress interference fields from its immediate environment. Infineon’s proprietary technology compensates temperature fluctuations and mechanical stress to reduce the sensitivity error of measurement to just two per cent at room temperature, and single point in-system calibration produces even lower values, says Rutronik. The results of the measurement are provided as an analogue output voltage.
For fast over-current detection with a low latency, the sensor contains two digital outputs (OCD1, OCD2). When the individually programmable over-current threshold is exceeded, the signal can be used for pre-warning or for system shutdown. The sensor also identifies and reports over- or under-voltage conditions for the supply voltage.
The TLI4971’s thermal performance for currents up to 120A is credited to its special current rail layout; it incorporates galvanic isolation for voltages up to 1.1kV. The compact sensor is provided in a 8.0 x 8.0 x 1.0mm leadless TISON-8 package and has 120kHz bandwidth, making it suitable for a range of applications, including 50kW electric drives, inverters, robots, chargers, battery management systems, smart metering, power tools and white goods.
The Xensiv TL14971 will be launched in October and will be available at Rutronik UK. Samples can be ordered now.
