The TMAG5110 and TMAG5111 are dual chopper-stabilized Hall effect sensors with two digital latched outputs for rotational magnetic sensing applications. The TMAG511x device can be powered with a supply voltage between 2.5 V and 38 V, and survives continuous –20-V reverse-battery conditions. The TMAG511x device only operates when a voltage of 2.5 V to 38V applied to the VCC pin (with respect to the GND pin). In addition, the device can withstand voltages up to 40 V for transient durations.
Alternating north and south magnetic poles are required to toggle the outputs of each Hall-effect latch.
The device is offered in a standard 3-mT typical operating point, as well as a high-sensitivity 1.4-mT typical operating point. The higher magnetic sensitivity provides flexibility in low-cost magnet selection and mechanical component placement. The TMAG511x is also available in three 2-axis combination options (X-Y, Z-X, Z-Y) to support flexible multiple installation orientations relative to the magnet.
