What this Hall sensor delivers for the BOM
The DRV5053VAELPGQ1 is a single-axis linear Hall-effect sensor from TI's automotive-qualified DRV5053 family. It outputs an analog voltage proportional to the applied magnetic field, with a sensing range of ±9 mT and a bandwidth of 20 kHz — enough to track field changes in motor-commutation and current-sense loops running at several kHz. The wide supply range, 2.7 V to 38 V, means it can sit on a 5 V or 12 V regulated rail without an extra LDO, saving a component and a PCB via.
The TO-92-3 through-hole package is a mature, widely second-sourced footprint, so the supply chain is stable for both prototype builds and sustained production runs. Texas Instruments is the sole brand on this order code.
Package and temperature grade fit
The TO-92-3 through-hole package is a three-lead inline format. The maximum supply current is 3.6 mA, and the maximum output current is 2.3 mA. These low current numbers mean the self-heating is negligible even in still air, so the thermal design is straightforward — no heatsink or airflow required.
