The deal combines Infineon’s sensor ICs with Swoboda’s expertise in sensor modules, and the first product (photo right) is aimed specifically at Infineon’s ‘HybridPACK Drive G2’ three-phase traction motor drive modules.
Later models will cover more general applications.
The infineon-specific model is called the Swoboda CSM510HP2, and is an encapsulated current sensor module is based on Infineon’s TLE4973 coreless current sensor IC. Its total sensing error is below 2%, said Infineon.
In use, it appears to be shaped to be inserted into correspondingly profiled slots already moulded into the drive modules (photo below). Electronics Weekly has asked for clarification.
There are two versions: the single-ended output CSM510HP2S and the differential output CSM510HP2D. Both run from 5V.
Measurements are up to ±1,600A and there is a dedicated over-current indication output that responds in <1.7µs. Bandwidth is above 120kHz.
Functional safety rating is ASIL-B (SEooC), and end-of-line calibration is available.
