XENSIV™ - TLE4972-AE35S5 magnetic coreless current sensor in a leadless VSON-6 package
The Infineon TLE4972 –AE35S5 is a high precision current sensor based on Hall technology. Due to its differential measurement principle it is robust against stray fields and suited for current measurements in EMC prone environments, e.g. in-phase current sensing in a motor application. The integrated Infineon proprietary, stress and temperature compensation together with the digitally assisted measurement concept, provide a very high stability over temperature and lifetime.
The well-established and robust Hall technology enables accurate and highly linear measurement of magnetic fields up to 31mT. All negative effects (saturation, hysteresis) commonly known from sensors using flux concentration techniques are avoided. The small VSON-6 package enables sensor implementation which causes very low power losses.
Our current sensor comes with two dedicated overcurrent pins for fast overcurrent detection for system protection. To support usage in safety critical applications like traction inverters of battery main switches the sensor is developed in accordance ISO 26262 as Safety Element out of Context fulfilling technical safety requirements up to ASIL B.
Summary of Features
- High accurate, scalable, DC & AC current sensing
- Very low sensitivity error over temperature and lifetime
- Excellent stability of offset over temperature and lifetime
- High bandwidth provides fast response time and low phase delay
- Differential sensor principle ensures superior magnetic stray field suppression
- Two independent fast Over-Current Detection (OCD) pins with configurable thresholds enable fast protection mechanisms for power circuitry (typical 0.7µs)
- Full scale up to 31 mT for high current applications
- Small form factor enables low insertion resistance and less power loss
- Configurable analog output operational modes (fully-differential, semi-differential or single-ended, uni- and bidirectional with or without ratiometricity)
- Supply voltage 3.1 to 3.5V
- ISO 26262 Safety Element out of Context for safety requirements up to ASIL B
- Different package solutions for optimal system integration in different wiring schemes
