Overview

The DRV5032FADBZR is an ultra-low-power omnipolar Hall effect switch designed for battery-operated systems. It operates from a wide 1.65V to 5.5V supply range and features a push-pull output that eliminates the need for an external pull-up resistor. The device triggers on either a North or South magnetic pole, making it ideal for proximity and position sensing where magnet orientation may vary.

Why Choose This Part

This sensor features an industry-leading sleep current of approximately 1.3uA at 1.8V, significantly extending battery life in mobile applications. The omnipolar sensitivity allows for simpler mechanical assembly by responding to either magnetic pole, while the integrated push-pull output reduces component count and PCB footprint.

Applications

Battery-Powered Proximity Sensing
Detecting the opening and closing of doors or lids in consumer electronics like laptops and tablets with minimal power draw.
Utility Meter Tamper Detection
Monitoring for external magnetic interference in electricity or water meters to prevent unauthorized bypass.
Medical Device Position Monitoring
Low-power position sensing in portable medical equipment and medication delivery systems.
Industrial Valve Feedback
Providing reliable digital feedback for valve positions in low-duty cycle industrial automation applications.

Getting Started

Engineers can evaluate this sensor using the DRV5032-SOLAR-EVM or by prototyping with the SOT-23 package on a standard breakout board. Since it is a digital switch, it can be connected directly to any microcontroller GPIO with an internal or external interrupt to wake the system upon magnetic detection.
