It detects the presence of either a north or south magnetic pole, making it suitable for lid-closure detection, proximity sensing, and contactless switch applications in portable and battery-powered devices. Operating from a supply voltage as low as 1.65 V, this sensor can run directly from a single alkaline or lithium coin cell without a boost converter. The push-pull output eliminates the external pull-up resistor, saving board space and reducing BOM count. ## Magnetic thresholds and temperature range for reliable switching The device switches at a typical magnetic flux density of ±50 mT (trip point) and releases at ±23.5 mT, providing a hysteresis window of approximately 26.5 mT. This hysteresis prevents output chatter when the magnet is near the threshold. The magnetic thresholds are specified at 25°C; temperature drift of the Hall plate will shift these values across the full range. The Sleep Mode feature (listed in the feature set) indicates the part enters a low-power state between sampling cycles, drawing minimal quiescent current. This makes it viable for always-on sensing in battery-powered designs where every microamp matters.","metaTitle":"TI TMAG5231H1DQDMRR Omnipolar Hall Switch, 1.65 V, Push-Pull","metaDescription":"Texas Instruments TMAG5231H1DQDMRR low-power omnipolar Hall-effect switch. 1.65 V min supply, push-pull output, ±50 mT trip point.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"feature_list":"Sleep Mode","package_type":"Tape & Reel (TR); Cut Tape (CT)","polarization":"North Pole, South Pole","mounting_type":"Surface Mount","output_signal":"Push-Pull","Test Condition":"25°C","product_status":"Active","lifecycle_stage":"eol_hot","timing_function":"Omnipolar Switch","supply_voltage_v":"1.65","switching_current_a":"0.0","output_current_max_a":"0.005","sensing_distance_max_mm":"±50mT Trip, ±23.5mT Release","Operating Temperature High":"-40°C to 125°C(TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.18","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TMAG5231H1DQDMRR/alternatives.json"},"ai":{"faq":[{"question":"What magnetic field strength does the TMAG5231H1DQDMRR switch at?","answer":"The TMAG5231H1DQDMRR has a typical trip point of ±50 mT and a release point of ±23.5 mT, measured at 25°C.
