What are the key features of TMAG5231A1CQDMRR?

Omnipolar input mode responds to both north and south magnetic poles, simplifying magnet alignment in mechanical designs
1.65 V to 5.5 V supply range compatible with 1.8 V IoT SoCs through 5 V automotive systems
Ultra-compact 1.4 mm x 1.1 mm x 0.35 mm package enables integration in the tightest wearable and mobile PCB layouts

What is TMAG5231A1CQDMRR used for?

The TMAG5231A1CQDMRR is suited for lid and door position detection in portable devices and appliances, where its omnipolar response allows a single magnet to reliably trigger the switch regardless of polarity orientation. Its 1.65 V minimum supply makes it compatible with modern energy-harvesting and low-voltage IoT modules that need contactless position sensing. The AEC-Q100 qualified variant also targets automotive interior position sensing such as seat adjustment, mirror position, and gear selector detection.

Frequently Asked Questions

What supply voltage range does TMAG5231A1CQDMRR support and which IoT supply rails are compatible?

The TMAG5231A1CQDMRR operates from 1.65 V to 5.5 V, covering 1.8 V low-power SoC rails, the common 3.3 V microcontroller supply, and 5 V systems. This wide range means the same part can be used without a regulator in battery-backed IoT nodes down to a nearly depleted 2-cell AA configuration at approximately 1.8 V.

How does the omnipolar input mode simplify magnet selection for a lid-close detection design?

In an omnipolar Hall switch, both a north-pole and a south-pole field above the operate threshold of approximately 2.7 mT trigger the output, so the designer does not need to specify magnet polarity during assembly. This halves the risk of misassembly and eliminates the need for orientation marking on the magnet, reducing bill-of-materials cost and assembly error rates in high-volume consumer products.

What hysteresis does TMAG5231A1CQDMRR provide and why does it matter in a vibrating environment?

The device has a 0.6 mT magnetic hysteresis band between the operate and release thresholds. In an environment with mechanical vibration such as a vehicle door panel, this hysteresis prevents output chatter when the magnet hovers near the switching point, ensuring a clean digital transition without debounce logic and reducing spurious interrupt events to the host microcontroller.
