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.
