High Sensitivity Analog Bipolar Hall Effect Sensor With Linear Voltage Output For Magnetic Field Measurement
The DRV5053VAQDBZR is a high-sensitivity analog bipolar Hall effect sensor designed for precise magnetic field measurement, position sensing, and motion control applications. Built using chopper-stabilized Hall-effect technology, the sensor delivers exceptional sensitivity and stability across temperature variations, ensuring accurate and repeatable magnetic field measurements. Its linear analog output responds proportionally to magnetic flux density while distinguishing between north and south magnetic field polarities, making it ideal for applications requiring directional magnetic sensing.
Operating from a wide supply voltage range of 2.5 V to 38 V, the DRV5053VAQDBZR can be directly connected to industrial power systems without requiring an external voltage regulator. The VA version offers a high sensitivity of -90 mV per mT, enabling accurate detection of small magnetic field changes. Integrated protection features, including reverse polarity protection, load dump protection, output short-circuit protection, and current limiting, ensure robust operation in demanding industrial and consumer environments. The compact SOT-23-3 package supports space-efficient PCB designs.
