Key Features
- Omnipolar sensing detects both north and south magnetic poles, simplifying magnet orientation requirements during mechanical assembly
- 1.65 V to 5.5 V supply range enables direct integration with 1.8 V IoT microcontrollers and 5 V industrial logic alike
- Ultra-compact 1.4 mm × 1.1 mm × 0.35 mm package fits magnetic proximity sensing into the smallest wearable and portable devices
Applications
TMAG5231H1DQDMRR is ideal for contactless position detection and proximity sensing in portable devices, wearables, and consumer electronics where board space is extremely limited. Its omnipolar operation simplifies assembly by eliminating the need to orient the magnet to a specific pole, reducing manufacturing complexity in lid-open detection, button replacement, and rotary encoder applications. The 1.65 V minimum supply makes it a natural companion for ultra-low-power microcontrollers in always-on sensing subsystems.

Frequently Asked Questions
What magnetic hysteresis does TMAG5231H1DQDMRR provide, and how does it prevent output chatter near the switching threshold?
TMAG5231H1DQDMRR has a built-in hysteresis of 6.5 mT, meaning the output switches on at one magnetic field level and does not switch off until the field decreases by 6.5 mT below that point. This dead-band prevents rapid toggling when a magnet is positioned near the threshold, eliminating the need for external RC debounce circuits. In a lid-detection application where the magnet moves at variable speeds, the 6.5 mT hysteresis ensures a clean, bounce-free digital output signal to the host MCU.
What is the maximum operating magnetic field range of TMAG5231H1DQDMRR, and which magnet types are compatible?
TMAG5231H1DQDMRR operates within a magnetic field range up to 50 mT. Standard neodymium magnets (NdFeB) with a surface field of 20 mT to 40 mT placed 2 mm to 5 mm from the sensor provide reliable switching well within this range. Ferrite magnets with lower field strength may require closer placement to reach the switching threshold, while very strong magnets placed directly on the package should be below the 50 mT limit to avoid saturating the internal Hall element.
How does omnipolar input mode in TMAG5231H1DQDMRR simplify product assembly compared to unipolar Hall switches?
A unipolar Hall switch responds only to a specific magnetic pole (north or south), requiring the assembly line to orient each magnet correctly and verify polarity before installation. TMAG5231H1DQDMRR's omnipolar mode responds to both poles equally, so the magnet can be placed in any rotational orientation and the sensor still activates at the same field magnitude. This eliminates a polarity-checking step, reducing assembly cycle time and rework rate in high-volume consumer electronics manufacturing.
What is the quiescent current consumption of TMAG5231H1DQDMRR in always-on proximity detection applications?
TMAG5231H1DQDMRR operates with a typical supply current of around 5 µA to 10 µA in continuous sensing mode, making it suitable for always-on wake-up functions in battery-powered devices. In a wearable device with a 100 mAh coin cell, the sensor alone draws under 1 mAh per day, extending battery life by years compared to polling-based optical proximity sensors that draw milliamps during active measurement windows.
