Product details
Overview
DRV5053RAQDBZR from Texas Instruments is a chopper-stabilized analog bipolar Hall effect sensor in 3-pin SOT-23 (DBZ) package, delivering –45 mV/mT sensitivity, 0.2–1.8 V ratiometric output, and operation from 2.5 V to 38 V supply. It provides linear magnetic field response with polarity discrimination, ±1% linearity, and 20 kHz bandwidth for precision position and motion sensing in harsh environments.
For engineers reviewing the DRV5053RAQDBZR datasheet, DRV5053RAQDBZR pinout, DRV5053RAQDBZR application, or DRV5053RAQDBZR equivalent, this page delivers verified technical context, real-world design meaning of specifications, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with functional and selection guidance.
Technical Context
The DRV5053RAQDBZR uses chopper stabilization to suppress offset drift and achieve ±10% sensitivity stability over –40°C to +125°C. Its analog output stage delivers 300 µA source / 2.3 mA sink capability with 35 µs power-on time and 13–25 µs output delay.
It features integrated reverse supply protection (–22 V), 40-V load dump tolerance, output short-circuit and current-limiting protection, and operates without external regulation across its full 2.5–38 V range - enabling direct battery connection in automotive and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –45 mV/mT (typical at VCC = 3.3 V, TA = –40°C to 125°C): enables high-resolution detection of weak magnetic fields down to ~0.5 mT resolution in closed-loop systems |
| Output Voltage Range | 0.2 V to 1.8 V (with 1.0 V quiescent at B = 0 mT): compatible with 3.3 V ADC reference rails and eliminates need for level-shifting circuitry |
| Supply Voltage Range | 2.5 V to 38 V: supports direct integration into 12 V/24 V automotive and industrial power buses without external regulators |
| Operating Temperature | –40°C to +125°C (AEC-Q100 qualified Q-grade): validated for under-hood, motor control, and factory automation environments |
| Bandwidth | 20 kHz: sufficient for real-time monitoring of rotating shafts up to 120,000 RPM with 1-pole magnet |
| Input-Referred Noise | 0.40–0.79 mTpp (TA = –40°C to 125°C): defines minimum detectable field change in vibration-sensitive applications like damper control |
| Power-On Time | 35 µs (max): ensures rapid system readiness after wake-up or cold start in battery-powered devices |
Pinout & Package
DRV5053RAQDBZR uses the 3-pin SOT-23 (DBZ) surface-mount package measuring 2.92 mm × 2.37 mm with standard JEDEC MO-178 footprint. Pin 1 is VCC, Pin 2 is OUT, Pin 3 is GND - confirmed per TI SLIS153D Figure 5-1 and Table 5-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power input | Accepts 2.5–38 V DC; requires ≥0.01 µF ceramic bypass capacitor to GND for stable operation and EMI suppression |
| OUT (Pin 2) | Analog output | 0.2–1.8 V linear voltage proportional to perpendicular magnetic flux density; sinks up to 2.3 mA or sources up to 300 µA |
| GND (Pin 3) | Reference ground | Return path for supply and output current; must be low-impedance connection to minimize noise coupling into sensitive analog output |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized architecture | Reduces offset drift to <1 µV/°C, enabling stable zero-field output (1.0 V ±120 mV) across full temperature range |
| Negative sensitivity (–45 mV/mT) | South pole near marked side lowers output below 1 V; north pole raises it - simplifies polarity-aware position feedback in rotary encoders |
| Integrated reverse supply protection | Withstands –22 V continuously on VCC-GND without damage or latch-up, eliminating need for external diode in battery-reversal-prone systems |
| Load dump immunity | Survives transient 40-V spikes on supply rail per ISO 7637-2 Pulse 5a, enabling use in automotive power networks without external TVS |
| Fast power-on response | Valid output within 35 µs of VCC reaching 2.5 V - critical for low-duty-cycle wake-up sensing in energy-constrained IoT nodes |
Applications
| Flow Meters | Docking Adjustment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053PAQDBZR | –23 mV/mT sensitivity (≈51% lower gain); 35 mT saturation field (≈2× higher than RA) | Better suited for stronger magnetic fields (>±20 mT) where higher dynamic range is needed over resolution | Select when magnet strength or air gap variability demands wider linear range rather than fine resolution |
| DRV5055VAQDBZR | –90 mV/mT sensitivity (2× RA); 9 mT saturation field; 5 kHz bandwidth (vs. 20 kHz) | Optimized for ultra-low-field detection but sacrifices speed and headroom in high-field scenarios | Choose only when target field is consistently <±5 mT and system bandwidth ≤5 kHz - avoid for rotating machinery |
Compared with DRV5053RAQDBZR, DRV5053PAQDBZR trades sensitivity for extended linear range, while DRV5055VAQDBZR doubles sensitivity at the cost of bandwidth and saturation margin - making DRV5053RAQDBZR the balanced choice for general-purpose industrial position sensing requiring both resolution and speed.

FAQ
What is the exact sensitivity value of DRV5053RAQDBZR and how is it specified?
The DRV5053RAQDBZR has a nominal sensitivity of –45 mV/mT, with a tested range of –70 mV/mT to –20 mV/mT across temperature (–40°C to +125°C) and supply voltage (3.3 V). This value is defined as the slope of the output voltage versus applied magnetic flux density and is confirmed in TI's SLIS153D datasheet Section 6.7 for the RA variant. The negative sign indicates that a south pole near the marked side of the package reduces the output voltage below the 1.0 V quiescent point.
Does DRV5053RAQDBZR require an external voltage regulator?
No, DRV5053RAQDBZR does not require an external voltage regulator. It operates directly from 2.5 V to 38 V DC supply voltage and includes internal regulation. A minimum 0.01 µF ceramic bypass capacitor between VCC and GND is required for stability, but no additional LDO or DC/DC converter is needed - simplifying power design in 12 V or 24 V systems.
What protection features are built into DRV5053RAQDBZR?
DRV5053RAQDBZR integrates reverse supply protection up to –22 V, transient load dump tolerance up to 40 V, output short-circuit protection, and output current limiting (300 µA source / 2.3 mA sink). These protections are implemented in silicon and do not rely on external components, enabling robust deployment in automotive battery-connected applications and industrial power environments subject to voltage transients.
What is the operating temperature range of DRV5053RAQDBZR and is it AEC-Q100 qualified?
DRV5053RAQDBZR is rated for –40°C to +125°C ambient operating temperature and carries the "Q" suffix indicating AEC-Q100 Grade 1 qualification. This certification confirms reliability testing for automotive applications including thermal cycling, humidity bias, and accelerated life testing - making it suitable for under-hood, transmission, and chassis-mounted sensing roles.
How does the output voltage of DRV5053RAQDBZR respond to magnetic field polarity?
DRV5053RAQDBZR outputs 1.0 V at zero magnetic field (B = 0 mT). With its –45 mV/mT sensitivity, a south pole near the marked side of the package (positive B-field) decreases the output voltage linearly (e.g., –10 mT → ~1.45 V), while a north pole (negative B-field) increases it (e.g., +10 mT → ~0.55 V). This bipolar response is explicitly defined in TI's SLIS153D Section 7.3.2 and Figure 7-2 for RA variants.
