Active production — what the lifecycle means for your BOM line
The DRV5032FADBZT: For a procurement desk qualifying a BOM position, active status means the authorized distribution channel continues to supply fresh-date-code inventory, and TI has not announced a successor or phase-out window.
3.5 µA supply with sleep mode — battery-life engineering
The DRV5032FADBZT draws a maximum of 3.5 µA from the supply rail, and the integrated sleep-mode feature drops the average current further when the magnetic field is absent — the device samples the field periodically and sleeps between samples, which is the dominant power-saving mechanism for always-on magnetic wake-up applications.
Omnipolar ±3 mT trip — which magnetic pole triggers the output
The omnipolar switch function responds to both north and south poles above the ±3 mT operate point, releasing at ±1.5 mT (hysteresis of 1.5 mT typical). This eliminates the need to orient the magnet polarity during assembly — either pole approaching the sensor face pulls the output low (push-pull,). The push-pull output sources or sinks up to 5 mA directly, so no external pull-up resistor is needed — the output drives a microcontroller GPIO or a low-power LED without additional components.
SOT-23-3 package — footprint and board integration
The DRV5032FADBZT ships in the standard SOT-23-3 package — a three-lead, surface-mount footprint that fits into the same PCB land pattern as many other small-signal transistors and Hall switches, simplifying BOM consolidation.
Temperature grade and deployment context
All specifications are characterized at 25°C — derate the operate/release points slightly across temperature per the TI datasheet's typical performance curves, though the ±3 mT / ±1.5 mT limits hold across the full range.
