3 Description

The TMAG5131-Q1 is an ultra-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. The output stays low until the flux density

decreases to less than the release point (BRP), and

then the device outputs a high voltage. Omnipolar

magnetic response allows the output to be sensitive

to both north and south magnetic fields.

The TMAG5131-Q1 is internally power cycled to

operate at a very low current consumption. The 20

Hz versions have current consumption of 2 μA at 3 V.

The TMAG5131-Q1 is available in the industrystandard

package and pin out SOT-23.

The device operates at a VCC range of 1.65 V to 5.5 V

as well as an extended temperature range of –40°C to

125°C.
