The TMAG5115 is a chopper-stabilized Hall sensor with a digital latched output for magnetic sensing applications. The TMAG5115 device can be powered with a supply voltage between 2.5 V and 26 V. The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic field, and a north pole near the marked side of the package is a negative magnetic field.

The output state is dependent on the magnetic field perpendicular to the package. A south pole near the marked side of the package causes the output to pull low (operate point, B_OP), and a north pole near the marked side of the package causes the output to release (release point, B_RP). Hysteresis is included in between the operate point and the release point therefore magnetic-field noise does not accidentally trip the output.

An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to V_CC or to a different voltage supply to allow for easier interfacing with controller circuits.
