Ultra Low Power Omnipolar Hall Effect Switch Sensor For Battery Sensitive Position Detection Applications
The DRV5032AJDBZR Magnetic Omnipolar Switch Hall Effect Sensor is an ultra-low-power digital magnetic sensing solution designed for compact, battery-powered, and energy-efficient electronic systems. Featuring omnipolar magnetic detection, the sensor responds to both north and south magnetic poles, simplifying magnetic alignment requirements and improving installation flexibility. Its highly efficient design makes it ideal for applications where extended battery life and reliable magnetic switching are critical.
Operating from a wide supply voltage range of 1.65 V to 5.5 V, the DRV5032AJDBZR incorporates an internal oscillator that periodically samples the magnetic field and updates the output while minimizing power consumption. The AJ version offers a maximum magnetic operating point of 9.5 mT, making it suitable for applications requiring moderate magnetic sensitivity. Housed in a compact SOT-23-3 package, the sensor provides dependable performance for portable electronics, IoT devices, smart meters, medical equipment, and contactless sensing systems.
