3 Description

The TMAG5131-Q1 is a low-power, 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 with a 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.
