The open-drain output pulls to ground when the field exceeds the trip threshold; a pull-up resistor to the logic rail is required. ## Omnipolar detection — one magnet, either pole Responds to both north and south poles — the output switches low when the field magnitude exceeds ±6 mT regardless of polarity. This simplifies magnet orientation in assembly: a magnet inserted backwards still triggers the switch. Surface-mount SOT-23 package — the small footprint fits tight PCB layouts near the magnet target. ## Active lifecycle — no end-of-life risk for new builds No stock-holding claim — availability verified per request.","metaTitle":"Texas Instruments TMAG5123B1CQDBZT Hall Switch, 2.5 V, ±6 mT","metaDescription":"Texas Instruments TMAG5123B1CQDBZT omnipolar Hall-effect switch. 2.5 V supply, ±6 mT trip, open-drain output, -40 to +125 °C.
