Single-axis linear Hall sensor with wide supply tolerance
The DRV5053RAQDBZTQ1 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 along a single axis, with a sensing range of ±18 mT. The supply voltage spans 2.7 V to 38 V, which means the sensor can run directly from a 12 V automotive battery rail or a 5 V regulated supply without an external LDO.
20 kHz bandwidth and temperature compensation
A 20 kHz bandwidth supports current sensing in motor-drive feedback loops and position sensing in fast-switching solenoids — the analog output settles within the PWM cycle of a 10-20 kHz switching stage. Maximum supply current is 3.6 mA, and the output can source or sink up to 2.3 mA — enough to drive the ADC input of a typical automotive microcontroller directly without a buffer. The SOT-23-3 package (TO-236-3, SC-59, SOT-23-3) is a standard three-pin footprint shared with many linear Hall sensors, easing layout reuse.
The base product number is DRV5053, and the suffix RAQDBZTQ1 denotes the ±18 mT sensitivity variant in the SOT-23-3 package on tape-and-reel. No official successor or pin-compatible second-source is recorded — the DRV5053 family covers the parametric range itself.
