It operates from a 2.7 V supply and draws 18 mA typical, with an output current capability of 7.8 mA max — sized for direct drive of a downstream logic input or indicator LED without an external buffer. The -40°C to 150°C ambient temperature range and AEC-Q qualification (implied by automotive designation) make it suitable for engine-bay or transmission-mounted position sensing where the board sees sustained heat and vibration. ## Current-source output — what it means for the load A current-source output delivers a constant current proportional to the field state, rather than a voltage swing — this gives noise immunity over long harness runs because the signal is a current loop, not a voltage referenced to ground. The 7.8 mA max output current means the switch can sink a standard PLC digital input or a 5 V logic gate directly; the 18 mA supply current is the total budget for the device plus the load, so the system designer must account for the load draw when sizing the 2.7 V rail.","metaTitle":"TI TMAG5124H1CEDBZRQ1 Hall Switch, 2.7V, South Pole","metaDescription":"Texas Instruments TMAG5124H1CEDBZRQ1 unipolar Hall switch, 2.7V supply, south pole sensing, 16.1mT trip.
