Magnetic thresholds and output behaviour
The DRV5032FDDMRT: The sensing range is ±4.8 mT trip, ±3 mT release, giving 1.8 mT of hysteresis that prevents output chatter when the magnetic field hovers near the threshold — a common failure mode in reed-switch replacement designs where mechanical bounce is absent but electrical noise is present. It is a unipolar switch that responds to both north and south poles, so the magnet orientation in the assembly is non-critical — either pole triggers the output, which simplifies fixture design and reduces tolerance stack-up concerns.
Package and temperature grade
Housed in a 4-XFDFN exposed-pad package (supplier device package 4-X2SON, 1.1 mm x 1.4 mm), the footprint is tiny — about the size of a 0402 resistor — making it suitable for space-constrained designs like wearable electronics or compact sensor modules.
