Single-axis Hall sensor with 20 kHz bandwidth
The DRV5053RAQDBZR is a single-axis linear Hall-effect sensor from Texas Instruments that outputs an analog voltage proportional to the magnetic flux density perpendicular to the package face. The ±18 mT sensing range suits moderate-field applications like current sensing through a bus bar or position sensing in a linear actuator. With a 20 kHz bandwidth, this sensor tracks fast-changing fields — useful for current feedback in a switching power supply or rotor position in a high-speed motor. The analog output connects directly to a microcontroller ADC without an external amplifier.
Automotive-grade temperature range and supply flexibility
Temperature compensation is built in — the output voltage drift over the full range is trimmed, so the sensitivity stays stable across the operating band. This matters when the sensor is mounted near a hot motor winding or exhaust manifold.
SOT-23-3 package and sourcing posture
The DRV5053RAQDBZR comes in a 3-pin SOT-23-3 surface-mount package (TO-236-3 / SC-59 equivalent). The small footprint fits tight PCB layouts in automotive ECU modules or compact sensor probes.
