The DRV5053CAEDBZRQ1 is a single-axis linear Hall-effect sensor from Texas Instruments, qualified to AEC-Q100 for automotive applications. It outputs an analog voltage proportional to the magnetic flux density perpendicular to the package face, making it suitable for linear position, rotary position, and current sensing in engine bay and transmission environments. Operating temperature spans -40°C to 150°C (ambient), covering the under-hood and transmission oil temperature bands where many commercial-grade sensors drop out.
Sensing range and bandwidth for position and current feedback
The ±35 mT sensing range matches the field strength of common neodymium and ferrite magnets used in rotary position sensing — a diametrically magnetized ring magnet with a 10 mm air gap typically produces 20–30 mT at the sensor face, leaving margin for temperature drift. 20 kHz bandwidth supports fast-switching current-sense applications such as motor phase current monitoring in a 10–20 kHz PWM inverter — the sensor's response time is fast enough to capture the average current without aliasing the switching ripple.
Package and board integration for space-constrained layouts
The SOT-23-3 package (TO-236-3, SC-59) occupies 2.9 mm × 1.6 mm of board area — the three-pin footprint fits between the motor phase traces on a compact inverter PCB or inside a sensor probe housing. Surface-mount assembly with standard reflow profile — no special handling beyond the usual ESD precautions for CMOS Hall sensors. The supply current draw is 3.6 mA max, so the self-heating in still air is negligible even at 150°C ambient.
The base product number DRV5053 covers multiple sensitivity options (A/B/C/D) and package variants — confirm the sensitivity grade (C = 35 mT range) and the tape-and-reel suffix (RQ1) match the BOM line before ordering.
