±9.5 mT operate — omnipolar detection without polarity management
The DRV5032AJDBZR is a Texas Instruments omnipolar Hall-effect switch that triggers on either a north or south pole exceeding the ±9.5 mT operate point, releasing at ±3 mT. This eliminates the need to orient the magnet or manage polarity in the firmware — a single sensor covers both directions of a passing ferrous target or a rotating magnet. The 3.5 µA max supply current means it can be left powered continuously in a battery-driven system without draining the cell between sampling intervals.
SOT-23-3 footprint and open-drain output
Housed in the three-lead SOT-23-3 (TO-236-3, SC-59), the DRV5032AJDBZR occupies minimal board area and matches the footprint of countless other Hall switches — a drop-in swap candidate for existing designs using the same package. The open-drain output sinks up to 5 mA and requires a pull-up resistor to the logic supply rail. Test conditions are specified at 25°C, so expect some temperature coefficient on the operate and release points across the full range — typical for Hall-effect sensors.
Active lifecycle — no end-of-life pressure for BOM planning
There is no NRND flag, no last-time-buy notice, and no announced discontinuation. The base product number DRV5032 covers a family of omnipolar switches with different sensitivity grades and packages. The AJDBZR variant is the ±9.5 mT / ±3 mT version in SOT-23-3 tape-and-reel packaging — confirm the sensitivity grade matches your magnetic circuit before committing the BOM line.
