3 Description

The TMAG5131-Q1 is a low-power, low-voltage, high-precision, Hall-effect sensor, designed for the most compact and battery-critical automotive applications. The device is offered in multiple magnetic thresholds, sampling rates and output types to accommodate various applications.

When the applied magnetic flux density exceeds the operating point (BOP) threshold, the device outputs a low voltage (for active-low versions). The output stays low until the flux density decreases to less than the release point (BRP), at which point the device outputs a high voltage. The output (low/high) behavior is inversed for active high versions. The omnipolar magnetic response allows the device output to be sensitive to positive and negative magnetic flux through the Z-axis of the package, while the unipolar version responds only to a positive magnetic flux.

The TMAG5131-Q1 is internally power cycled to operate at a very low current consumption. At 3V, the 10Hz version has an average current consumption of 1.25μA, and the 20Hz versions consume 1.37μA.

The TMAG5131-Q1 is available in an industry-standard SOT-23 package and pin out.

The device operates at a VCC range of 1.65V to 5.5V as well as an extended temperature range of –40°C to 125°C.
