Single-axis linear Hall sensor for automotive and industrial position/current sensing
The Texas Instruments DRV5053RAQLPGMQ1 is a single-axis Hall-effect sensor that outputs an analog voltage proportional to the applied magnetic flux density, with a sensing range of ±18 mT. The analog output simplifies direct connection to an ADC — no external digital interface or protocol decoding is needed.
AEC-Q100 qualification and wide supply margin
AEC-Q100 Grade 0/1 qualification (the part is listed as Automotive grade) means the sensor has passed the stress tests required for automotive PPAP — extended temperature cycling, ESD, and latch-up immunity. For a BOM that ships into a vehicle or heavy-equipment ECU, this grade is the gate requirement. The 2.7 V to 38 V supply range gives headroom for a 12 V battery that dips to 4.5 V during cold crank and surges past 36 V during a load dump — the internal biasing stays within regulation without an external clamp.
Through-hole TO-92-3 package and sourcing posture
The TO-92-3 through-hole package (3-pin, short-body variant) is a standard footprint for Hall sensors — it plugs into a 0.100-inch pitch header or solders directly into a PCB. The single-axis orientation senses flux perpendicular to the package face; the datasheet shows the sensitive axis relative to the flat side. Texas Instruments lists this part as Active (current lifecycle stage).
