Key Features
- Omnipolar Hall-effect switching responds to both north and south magnetic poles, eliminating magnet orientation constraints in proximity-detection designs
- Ultra-wide 1.65 V to 5.5 V supply range with 0.6 mT hysteresis for stable, bounce-free switching from coin-cell to 5 V systems
- Tiny 3-pin SOT-23 plastic package (2.92 mm x 1.3 mm x 0.95 mm) with 15-year YTEOL, ideal for compact long-lifecycle consumer and industrial products
Applications
The TMAG5231A1CQDBZR detects magnet proximity in portable consumer devices, lid-close sensors, and end-of-travel switches where its 1.65 V minimum supply enables direct coin-cell or LDO-regulated operation. Its omnipolar input mode simplifies mechanical assembly by removing the need to align magnet polarity. The 3-pin SOT-23 footprint fits easily alongside microcontrollers on compact IoT sensor boards with minimal BOM impact.

Frequently Asked Questions
What supply voltage range and magnetic sensitivity does TMAG5231A1CQDBZR offer for battery-powered sensor designs?
The TMAG5231A1CQDBZR operates from 1.65 V to 5.5 V, making it compatible with a single lithium coin cell, two AAA cells, or a regulated 3.3 V or 5 V rail. The magnetic switch threshold sits within a 2.7 mT maximum field range with 0.6 mT of hysteresis, ensuring stable output transitions without chatter even in environments with mild mechanical vibration.
How does the omnipolar mode of TMAG5231A1CQDBZR simplify lid-close sensor assembly compared to a unipolar Hall switch?
An omnipolar Hall-effect switch activates regardless of whether the approaching magnet presents its north or south pole, so the assembly team does not need to orient magnets during installation. This reduces assembly errors and allows interchangeable magnet placement, cutting production costs in high-volume lid-close or cover-detect applications such as laptop hinges or appliance door sensors.
What are the physical dimensions of the TMAG5231A1CQDBZR SOT-23 package, and how does this affect PCB layout?
The SOT-23 body measures 2.92 mm long, 1.3 mm wide, and 0.95 mm high with a plastic housing. This miniature footprint requires only a small pad area on the PCB, typically about 3 mm x 2.5 mm including solder pads, enabling placement close to a magnet actuator in wearables, smart cards, and compact industrial proximity sensors.
Is TMAG5231A1CQDBZR a good long-term supply choice, and what is its RoHS status?
Yes, the part has a YTEOL (years to end of life) rating of 15 years, indicating strong long-term supply commitment from Texas Instruments. It carries a Pb-free RoHS-compliant e3 finish, suitable for consumer and industrial products requiring lead-free solder assembly, and it is available in tape-and-reel (DBZR suffix) for automated SMT production.
