Functional Description

2.1

General

The TLE4906K and the TLE4906L are integrated circuit Hall-effect sensors designed specifically for highly

accurate applications.

Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and

chopper techniques on chip.

Functional Block Description

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 technology variations.

The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall

probe caused by molding and soldering processes and other thermal stresses in the package.

This chopper technique together with the threshold generator and the comparator ensure high accurate magnetic

switching points.

1) over operating range, unless otherwise specified. Typical values correspond to V_S= 12V and T_A= 25°C

2) To operate the sensor at the max. switching frequency, the value of the magnetic signal amplitude must be 1.4 times higher

than for static fields. This is due to the -3dB corner frequency of the low pass filter in the signal path.

3) Systematic delay between magnetic threshold reached and output switching.

4) Jitter is the unpredictable deviation of the output switching delay.

5) Time from applying V_S≥ 2.7V to the sensor until the output state is valid.

6) Thermal resistance from junction to ambient.
