Offset voltages generated by temperature-induced stress or overmolding are canceled so that high accuracy is achieved. The IC has an open collector output stage with 20 mA current sink capability. A wide operating voltage range from 2.7 V to 18 V with reverse polarity protection down to -18 V makes the TLI4946xy suitable for a wide range of applications. A magnetic south pole with a field strength above Bop turns the output on. A magnetic north pole exceeding Brp turns it off. 1.2 Pin configuration Center of Sensitive Area 2.08 ± 0.1 3 1.35 0.8 1 1.5 ± 0.1 ± 0.15 2 ± 0.15 1 2 3 PG-SSO-3-2 SC59 Figure 1 Pin configuration and sensitive area (Top view, figure not to scale) 1.3 Pin description Table 1 PIN Definitions for the PG-SC59-3-4 package PIN No. Name Function 1 VS Supply Voltage 2 Q Output 3 GND Ground Table 2 PIN Definitions for the PG-SSO-3-2 package PIN No. Name Function 1 VS Supply Voltage 2 GND Ground 3 Q Output Datasheet 3 Rev. 1.1 2020-08 TLI4946K, TLI4946-2K, TLI4946-2L High Precision Hall Effect Latches for Industrial and Consumer Applications 1 Functional description 1.4 Block diagram VS Voltage Regulator reverse polarity protected Bias and Compensation Circuits Oscillator and Sequencer Q Ref Amplifier Chopped Hall Probe Figure 2 Datasheet Low Pass Filter Comparator with Hysteresis GND TLI4946xy Block diagram 4 Rev. 1.1 2020-08 TLI4946K, TLI4946-2K, TLI4946-2L High Precision Hall Effect Latches for Industrial and Consumer Applications 1 Functional description 1.5 Operating modes and states Field Direction and Definition Positive magnetic fields correspond to the south pole of the magnet targeting the branded side of the package.

The bias generator provides currents to the Hall probe and the active circuits. Compensation circuits stabilize response of the IC over temperature and reduce the impact of process variations. The Active Error Compensation rejects offsets in the signal path and reduces the impact of mechanical stress in the package caused by molding, soldering and thermal effects. The chopper technique together with the threshold generator and the comparator ensure high accurate magnetic switching points.
