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.

When the magnetic field is reduced to a value smaller than the release point, the output of the IC turns off (Release Point; Figure 4). + Branded Side Ι S VQ N + Figure 3 VS - AES01231 Sensor/Magnetic-Field Configuration B BOP Induction BRP 0 t VQ VQH Output Voltage VQL t AED01420 Figure 4 Data Sheet Switching Characteristics Unipolar Type 4 2000-07-01 TLE 4905 G; TLE 4935 G TLE 4935-2 G; TLE 4945-2 G Functional Description Bipolar Type TLE 4935/35-2/45-2 (Figure 5 and 6) When a positive magnetic field is applied in the indicated direction (Figure 5) and the turn-on magnetic induction BOP is exceeded, the output of the Hall-effect IC will conduct (Operate Point). The output state does not change unless a reverse magnetic field exceeding the turn-off magnetic induction |BRP| is exceeded. In this case the output will turn off (Release Point; Figure 6). + Branded Side Ι S VQ N + Figure 5 VS - AES01231 Sensor/Magnetic-Field Configuration B BOP 0 t Induction BRP VQ VQH Output Voltage VQL t AED01421 Figure 6 Data Sheet Switching Characteristics Bipolar Type 5 2000-07-01 TLE 4905 G; TLE 4935 G TLE 4935-2 G; TLE 4945-2 G Absolute Maximum Ratings Tj = – 40 to 150 °C Parameter Supply voltage Supply voltage Output voltage Output current Output reverse current Junction temperature Storage temperature Thermal resistance Symbol VS VS VQ IQ – IQ Tj Tstg Rth JA Limit Values Unit Remarks min. max. – 40 32 V – – 40 V t < 400 ms; ν = 0.1 – 32 V – – 100 mA – – 100 mA – – 40 150 °C – – 50 150 °C – 100 K/W – Note: Stresses above those listed here may cause permanent damage to the device.
