It is a member of the DRV5023 family, packaged in a three-pin SOT-23-3 for surface-mount assembly. The device switches its open-drain output low when the magnetic flux density exceeds the ±12 mT trip point (BOP) and releases (returns high) when the field drops below ±1 mT (BRP). This hysteresis — 11 mT typical — prevents output chatter at the switching threshold. ## Sensing thresholds and temperature stability The temperature-compensated design keeps the magnetic thresholds stable as the silicon heats up — important for applications where the sensor sits near a motor winding or exhaust path that pushes junction temperature well above 85°C. Because it responds only to a south pole, the sensor ignores north-pole fields that might be present from nearby magnets or stray fields in the assembly. This polarity-specific switching simplifies system-level magnetic design — you do not need to shield the sensor from the wrong pole. ## Output drive and supply considerations The open-drain output sinks up to 30 mA maximum, with a typical switching current of 2.7 mA. The SOT-23-3 footprint is a standard three-lead package with 0.95 mm pitch — the same land pattern used by many small-signal transistors and diodes, so the PCB layout is straightforward and the sensor can be placed close to the magnet target without a large pad footprint.","metaTitle":"TI DRV5023AJQDBZT Unipolar Hall Switch, SOT-23, ±12mT","metaDescription":"Texas Instruments DRV5023AJQDBZT unipolar Hall-effect switch, south-pole activated, ±12mT trip point, open-drain output, SOT-23-3, -40°C to 150°C, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"has_mpn":"DRV5023","feature_list":"Temperature Compensated","package_type":"Tape & Reel (TR); Cut Tape (CT)","polarization":"South Pole","mounting_type":"Surface Mount","output_signal":"Open Drain","Test Condition":"-40°C to 125°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Unipolar Switch","supply_voltage_v":"2.5","switching_current_a":"0.0027","output_current_max_a":"0.03","sensing_distance_max_mm":"±12mT Trip, ±1mT Release","Operating Temperature High":"-40°C to 150°C(TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.53","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dafac18d30418c20d0cd7743f41c29b4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DRV5023AJQDBZT/alternatives.json"},"ai":{"faq":[{"question":"What does the ±12 mT trip point mean for my application?","answer":"The ±12 mT operate point means the sensor switches when a south-pole field of at least 12 mT reaches the package face. The ±1 mT release point gives 11 mT of hysteresis, so the output does not bounce when the magnet moves slowly past the threshold. For a typical N35 neodymium magnet, this translates to an air-gap detection range of a few millimeters depending on magnet size."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV5023AJQDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV5023AJQDBZT when reusing this data.
