3 Description
The TMAG5131-Q1 is a low-power, low-voltage, highprecision,
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 industrystandard
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.
