Bipolar IC

TLE 4905/35/35-2/45 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.

TLE 4905 L; TLE 4935 L; TLE 4935-2 L; TLE 4945 L; TLE 4945-2L 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.
