Key Features
- Omnipolar Hall-effect switch responding to both north and south magnetic poles with 1.35 mT hysteresis for reliable switching
- Ultra-wide 1.65 V to 5.5 V supply range in a 1.4 mm x 1.1 mm x 0.35 mm package enabling integration into the smallest wearable and IoT designs
- Low-power operation with 3.8 mT magnetic field range supporting compact magnet arrays in proximity and position sensing applications
Applications
TMAG5231B1DQDMRR is ideal for contactless position detection in wearable health monitors, earbuds lid sensors, and portable consumer devices where board space is under 2 mm x 2 mm and supply voltage varies from 1.65 V to 5.5 V. Its omnipolar sensitivity eliminates the need to align a specific magnetic pole, simplifying magnet placement in mechanical assemblies. Industrial applications include end-of-travel detection in miniature actuators and door latch sensing in appliances requiring RoHS-compliant e3 construction.

Frequently Asked Questions
What magnetic field range and hysteresis does TMAG5231B1DQDMRR support, and why do these values matter for switch bounce?
TMAG5231B1DQDMRR has a maximum magnetic field range of 3.8 mT and a hysteresis of 1.35 mT. The 1.35 mT hysteresis prevents output chatter when the magnet hovers near the switch threshold, ensuring clean digital transitions without software debouncing in applications where the magnet moves slowly or vibrates near the 3.8 mT operate point.
For a wearable earbud case lid sensor, how does the TMAG5231B1DQDMRR package size compare to a typical SOT-23 Hall sensor?
TMAG5231B1DQDMRR measures 1.4 mm x 1.1 mm x 0.35 mm, which is roughly 3x smaller than a 2.9 mm x 1.6 mm SOT-23 package. This sub-2 mm footprint allows placement inside a hinge area or lid channel where only 2 mm x 2 mm of PCB area is available, making it the preferred choice over SOT-23 Hall sensors for ultra-compact consumer device lid detection.
Can TMAG5231B1DQDMRR operate directly from a 1.8 V MCU rail, and what supply current should be budgeted?
Yes, TMAG5231B1DQDMRR operates from 1.65 V to 5.5 V, so a 1.8 V MCU rail falls well within its supply range. The device is specified for low-power operation; typical quiescent current is in the low µA range, allowing it to be powered continuously in duty-cycled IoT designs with coin-cell batteries targeting multi-year 1 µA average system current budgets.
