Reverse polarity protection is included onchip as is output protection against negative voltage transients. Typical applications are position/proximity indicators, brushless DC motor commutation, rotational indexing etc. Data Sheet 1 2007-05 TLE4905L, TLE4935L, TLE4945L, TLE4945-2L Pin Configuration (view on branded side of component) Center of sensitive area 2.08 ±0.1 1.35 ±0.1 1 2 3 VS GND Q AEP01364 Figure 1 Pin Definitions and Functions Pin No. 1 2 3 Symbol Function Supply voltage Ground Output VS GND Q Data Sheet 2 V1.5, 2007-11 TLE4905L, TLE4935L, TLE4945L, TLE4945-2L 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 Schmitttrigger with open-collector output. A protection diode against reverse power supply is integrated. The output is protected against electrical disturbances.

When the current is reduced, the output of the IC turns off (Release Point; Figure 4). + Branded Side Ι S N VQ + VS - AES01231 Figure 3 Sensor/Magnetic-Field Configuration B BOP BRP 0 VQ VQH Output Voltage VQL t AED01420 Induction t Figure 4 Switching Characteristics Unipolar Type Data Sheet 4 V1.5, 2007-11 TLE4905L, TLE4935L, TLE4945L, TLE4945-2L Functional Description Bipolar Type TLE4935/45/45-2 (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 iinduction BRP is exceeded. In this case the output will turn off (Release Point; Figure 6). + Branded Side Ι S N VQ + VS - AES01231 Figure 5 Sensor/Magnetic-Field Configuration B BOP 0 BRP t Induction VQ VQH Output Voltage VQL t AED01421 Figure 6 Switching Characteristics Bipolar Type Data Sheet 5 V1.5, 2007-11 TLE4905L, TLE4935L, TLE4945L, TLE4945-2L Absolute Maximum Ratings Tj = – 40 to 150 °C Parameter Supply voltage Supply voltage Output voltage Output current Output reverse current Junction temperature Junction temperature Junction temperature Storage temperature Thermal resistance Symbol Limit Values Unit Remarks min. max. 32 40 32 100 100 150 170 210 150 190 V V V mA mA °C °C °C °C – – 40 – – – – – 40 – – – 50 – VS VS VQ IQ – IQ Tj Tj Tj Tstg Rth JA t < 400 ms; ν = 0.1 – – – – 1000 h 40 h – K/W – Note: Stresses above those listed here may cause permanent damage to the device.
