Active production — AEC-Q100 Hall sensor for position and current sensing
The Texas Instruments DRV5053VAQDBZTQ1 is a single-axis linear Hall-effect sensor producing an analog output voltage proportional to the perpendicular magnetic flux density. Rated for ±9 mT sensing range with a 20 kHz bandwidth, it responds fast enough for rotor-position feedback in brushless-DC motor commutation or for valve-position monitoring in transmission control modules. No additional derating is required for engine-bay or cabin-mounted sensor nodes. Current consumption is 3.6 mA max, and the output can source or sink up to 2.3 mA — enough to drive the ADC input of a typical automotive MCU without a buffer.
SOT-23-3 footprint and board integration
The DRV5053VAQDBZTQ1 comes in a three-pin SOT-23-3 package — a standard small-signal footprint shared by many linear Hall sensors. The pinout is supply, ground, and analog output; no external components are required for basic operation. The small body saves board space in space-constrained modules like pedal-position sensors or gear-shift actuators. Because the output is ratiometric to the supply voltage, the ADC reference should track Vcc to maintain accuracy across the 2.5 V to 38 V range. A 100 nF bypass capacitor close to the supply pin is recommended to keep the internal bias stable.
The base product number DRV5053 covers multiple sensitivity and output variants; the full suffix identifies this specific ±9 mT analog version in the SOT-23-3 package.
