Low-power, low-voltage (1.65 V to 5.5 V) Hall-effect switch

The TMAG5231 is a 2nd-generation,

low-power Hall-effect switch sensor, specifically designed to optimize the total

system cost for compact, battery-operated consumer and industrial 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 TMAG5231 is able to operate at

very low current consumption. To achieve 2 µA of current consumption the device is

internally power cycled at a 20-Hz rate.

The TMAG5231 is available in the

industry-standard package and pinout SOT-23 as well as X2SON.

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.
