TLE 4905/35/35-2/45/45-2 L (Unipolar/Bipolar Magnetic Field Switches) have been  
designed specifically for automotive and industrial applications. Reverse polarity  
protection is included on-chip as is output protection against negative voltage transients.  
Typical applications are position/proximity indicators, brushless DC motor commutation,  
rotational indexing etc.

Circuit Description  
The circuit includes Hall generator, amplifier and Schmitt-Trigger on one chip. The  
internal reference provides the supply voltage for the components. A magnetic field  
perpendicular to the chip surface induces a voltage at the hall probe. This voltage is  
amplified and switches a Schmitt-trigger with open-collector output. A protection diode  
against reverse power supply is integrated. The output is protected against electrical  
disturbances.

Functional Description Unipolar Type TLE 4905 (Figure 3 and 4)  
When a positive magnetic field is applied in the indicated direction (Figure 3) and the  
turn-on magnetic induction BOP is exceeded, the output of the Hall-effect IC will conduct  
(Operate Point). When the current is reduced, the output of the IC turns off (Release  
Point; Figure 4).
