TLE4961-1M Electronic Components

TLE4961-1M Electronic Componentsbelongs to High Precision Automotive Bipolar Hall Effect Latch of infineon electronic components. The TLE4961-1M is an integrated Hall effect latch designed specifically for highly accurate applications with superior supply voltage capability, operating temperature range and temperature stability of the magnetic thresholds

The chopped Hall IC switch comprises a Hall probe, bias generator, compensation circuits, oscillator and output transistor. The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the temperature behavior and reduce influence of technology variations.

The active error compensation (chopping technique) rejects offsets in the signal path and the influence of mechanical stress to the Hall probe caused by molding and soldering processes and other thermal stress in the package. The chopped measurement principle together with the threshold generator and the comparator ensures highly accurate and temperature stable magnetic thresholds

Product  Applications

Target applications for the TLE496x Hall Latch family are all applications which require a high precision Hall Latch with an operating temperature range from -40°C to 170°C. Its superior supply voltage range from 3.0 V to 32 V with overvoltage capability (e.g. load-dump) up to 42 V without external resistor makes it ideally suited for automotive and industrial applications. The magnetic behavior as a latch and switching thresholds of typical ±2 mT make the device especially suited for the use with a pole wheel for index counting applications, e.g. power closing and window lifter.
