We develop sensors for a wide range of industrial applications, including renewable energy,industrial automation and e-mobility. Our offering here includes products such as magnetic position and speed sensors as well as integrated pressure sensors and current sensors. In the case of electric drives – a key area in industrial applications – our portfolio comprises a full range of energy-saving sensors for electric commutated drives. In the increasingly important solar sector, our current sensors help our customers achieve optimum system efficiency and meet country-specific regulations.

  
　

　

TLI4970 is a high-precision current sensor based on Infineon´s proven Hall technology. The coreless concept significantly reduces footprint compared with existing solutions. TLI4970 is an easy-to-use, fully digital solution that does not require external calibration or additional parts such as A/D converters, OP amps or reference voltage. It thus significantly reduces overall implementation effort as well as PCB space and cost.

TLI4970 is more accurate than existing open- or closed-loop systems with magnetic cores. It also provides additional functions such as overcurrent detection and programmable filters yet has a significantly smaller footprint and lower power consumption. TLI4970 is extremely robust against external magnetic fields thanks to implemented strayfield suppression and is also suitable for fast overcurrent detection at a pre-configurable level. This allows the control unit to switch off independently of the main measurement path and protect power consumers from damage.

Integrated Pressure Sensor ICs

　

　

Infineon’s integrated pressure sensor family uses a unique design of multiple surface micro-machined capacitive sensor cell arrays, that allows to implement powerful features like the sensor self diagnoses. The monolithic integration onto one chip allows a state-of-the-art production using a standard automotive qualified BiCMOS process. The combination of sensor cell design with a fully digital signal conditioning and processing with the methods of a high volume standard production flow ensure a superior quality over lifetime.
　

Pressure Sensors for Automotive Applications

　

　

Today’s automotive applications are side crash detection, pedestrian protection, engine management (BAP, MAP, Turbo MAP, secondary air valve),fuel vapour, break booster and seat comfort. The next generation pressure sensors will offer digital interfaces like SPI, SENT and PSI5.

　

Pressure Sensors for Industrial & Consumer Applications

　

　

Pressure Sensors can be used in industrial and consumer applications such as altimeters, weather stations & many more. Our pressure sensor  family is available with different pressure ranges and interface options (analog and digital) according to the needs of the individual application.
