Resistor Adjustable Low Power Omnipolar Hall Effect Switch For Battery Powered Position Sensing Applications
The TMAG5328A1DQDBVR Resistor Adjustable Hall Effect Switch is a high-precision, low-power magnetic sensing solution designed for battery-operated and space-constrained electronic systems. Featuring an adjustable magnetic operating point through an external resistor, the sensor allows designers to customize the switching threshold between 2 mT and 15 mT to match specific application requirements. This flexibility enables rapid prototyping, simplified design updates, and component standardization across multiple product platforms.
The sensor features omnipolar magnetic detection, allowing activation by either north or south magnetic poles. An integrated internal oscillator periodically samples the magnetic field to minimize power consumption while maintaining reliable switching performance. Operating from a supply voltage range of 1.65 V to 5.5 V and housed in a compact SOT-23-6 package, the TMAG5328A1DQDBVR is ideal for battery-critical position sensing, tamper detection, IoT devices, medical equipment, and contactless activation systems.
