Linear Halls

Our latest Infineon XENSIV™ TLE4999C8 provides all means that are necessary to fulfill the state-of-the-art functional safety requirements on system level. It is developed in full compliance with ISO 26262. The device provides high redundancy on one chip by means of two sensor elements included within one monolithic silicon design. The two diverse Hall sensor elements („main” and „sub”) have internally separated signal paths within the chip. A plausibility check secures the high diagnostic coverage required for premium functional safety compliant systems up to ASIL D.

Our TLE499x linear Hall ICs familly is the ideal choice for highly accurate angular and linear position detec­tion and current measurement applications. Our sensors measure the vertical component of a magnetic field and outputs a signal that is directly proportional to the magnet­ic field. Infineon´s programmable linear Hall sensors come with different interface options PWM, SENT or SPC.

In the field of steering torque sensing, Infineon’s TLE499x series offers highly accurate linear Hall sensors for magnet­ic torque sensing assembly. In order to support a maximum of compatibility with various Electronic Control Unit (ECU) designs, the TLE499x sensors feature PWM, SENT, SPC or ratiometric analog output. They are available in leaded packages, as well as 1 mm-thick dual- or single-sensor SMD packages.

Thanks to the use of innovative stack-mounting technology, the devices of the angle sensor family combine two independent sensors within standard and space-saving TDSO packages which are only about 1 mm thick. It has the same width and length as a conventional single-sensor package. Compared to the common approach of side-by-side sensor placement, the advantages of the top-bottom placement include a more homogeneous magnetic field over the sensing elements and a significantly smaller footprint. This saves precious space and cuts down on expense in safety- critical applications, as a lower-cost ferrite magnet can provide a sufficient magnetic field for the sensors.
