Accurate & stable current measurement up to 120A or 31mT respectively. We offer integrated current rail for low currents & external current rail for medium to high currents.
The Infineon current sensors provide accurate and stable current measurement up to 120A or 31mT respectively. We offer sensors with integrated current rail for low currents as well as external current rail for medium to high currents. The products are intended for use in 48V as well as high voltage applications such as traction inverters, industrial drives, photovoltaic inverters, or battery disconnect systems.
The coreless open-loop sensors are based on Infineon’s precise and stable Hall technology. Thus the output signal is highly linear over temperature and lifetime. Due to lack of an iron core the sensor signal shows neither hysteresis nor does it suffer from saturation.
The differential measurement with two Hall cells ensures high accuracy even in a noisy environment with cross-talk from adjacent current lines or magnetic stray fields. Designers can program the sensitivity of the sensor as well as the threshold levels of the two dedicated overcurrent signals and thus adapt them to individual requirements without any external components. The sensor also provides a signal in case of an over- or under-voltage condition for the supply voltage.
Highlights of the XENSIV TLI4971 include best-in-class thermal performance for high currents due to its innovative TISON-8 package as well as isolation against high voltages. Due to the integrated current rail there is no need for external calibration.
Highlights of the XENSIV TLE4972 include a full scale up to ±31mT it is possible to measure currents up to 2,000 ampere. All negative effects (e.g. saturation, hysteresis) commonly known from open loop sensors using flux concentration techniques are avoided.
The sensor is an ISO 26262 Safety Element out of Context for safety requirements up to ASIL B and is equipped with internal self-diagnostics.
