Product details
Overview
DRV5053OAEDBZRQ1 from Texas Instruments is an AEC-Q100 Grade 0 automotive analog bipolar Hall effect sensor in a 3-pin SOT-23 (DBZ) package, delivering –11 mV/mT sensitivity, 0.2–1.8 V ratiometric output, and ±10% sensitivity stability over –40°C to +150°C ambient. It operates from 2.7–38 V, features 35 µs power-on time, and is used for precise linear magnetic field measurement in damper controls and flow meters.
For engineers reviewing the DRV5053OAEDBZRQ1 datasheet, DRV5053OAEDBZRQ1 pinout, DRV5053OAEDBZRQ1 application, or DRV5053OAEDBZRQ1 equivalent, key selection criteria include its negative sensitivity polarity, wide supply range with reverse-battery protection (–22 V), integrated output short-circuit and load-dump resilience, and compatibility with microcontroller ADC inputs requiring >10 kΩ load impedance.
Technical Context
The DRV5053OAEDBZRQ1 uses chopper-stabilized Hall sensing to achieve high temperature stability and low drift, with quiescent output fixed at 1 V (±102 mV) at zero magnetic field. Its analog output responds linearly to perpendicular magnetic flux density across –73 mT to +73 mT, distinguishing polarity via voltage direction relative to VQ.
Internally, it integrates a regulated supply, offset cancellation, and an amplified output stage capable of 300 µA source / 2.3 mA sink current. Protection includes reverse-supply survival up to –22 V, transient tolerance to 40 V load dump, and analog current limiting on the OUT pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –11 mV/mT: Output decreases 11 mV per millitesla increase in south-pole field applied to marked side. |
| Output Range | 0.2 V to 1.8 V: Full-scale saturation limits ensure compatibility with 2-V ADC reference rails. |
| Quiescent Output (VQ) | 0.9–1.15 V at B = 0 mT: Tight 1 V center point enables bidirectional field detection with minimal offset calibration. |
| Supply Voltage | 2.7–38 V: Eliminates need for external regulator in 12 V/24 V automotive systems; supports cold-crank and load-dump transients. |
| Operating Temperature | –40°C to +150°C (Grade 0): Validated for under-hood applications including engine control and transmission sensors. |
| Power-On Time | 35 µs max: Enables fast-response closed-loop control in vibration correction and real-time position feedback. |
| Input Noise (BN) | 0.40–0.79 mTpp: Low noise floor supports resolution of sub-millitesla field changes in precision flow metering. |
Pinout & Package
SOT-23 (DBZ) package: 2.92 mm × 2.37 mm surface-mount footprint with gull-wing leads; RoHS-compliant, Level-1 MSL rating, NIPDAUAG lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power input | Accepts 2.7–38 V; requires ≥0.01 µF ceramic bypass capacitor to GND for stable operation and EMI suppression. |
| GND (Pin 3) | Reference ground | Return path for supply and output current; must be low-impedance to minimize offset error and noise coupling. |
| OUT (Pin 2) | Analog output | 0.2–1.8 V linear response to B-field; drives loads >10 kΩ; capacitive load <10 nF required for amplifier stability. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces offset drift to ±10% sensitivity variation over full temperature range, enabling robust operation without recalibration. |
| Negative sensitivity (–11 mV/mT) | South pole near marked side pulls output below 1 V; north pole raises it-ideal for directional sensing in docking adjustment. |
| Reverse supply protection | Survives –22 V continuously on VCC-GND; prevents latch-up or damage during battery misconnection in automotive service. |
| Load dump resilience | Withstands 40 V transients without external clamping-meets ISO 7637-2 Pulse 5a requirements for 24 V systems. |
| Output short-circuit protection | Clamps sink current at 2.3 mA and source at 300 µA, preventing thermal runaway during wiring faults or PCB shorts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053PAEDBZRQ1 | –23 mV/mT sensitivity (≈2× higher gain); same package, temp grade, and protection features. | Better suited for low-field applications (<30 mT) where higher resolution is needed; requires lower field strength for full-scale output. | Select when system magnets are weak or air gaps are large; verify signal chain headroom given doubled slope. |
| DRV5055VAQDBZRQ1 | –90 mV/mT sensitivity; Q-grade (–40°C to +125°C); same DBZ package but no Grade 0 option. | Higher gain enables smaller magnets or tighter tolerances, but reduced max operating temperature limits under-hood use. | Choose for cost-sensitive non-under-hood applications needing maximum sensitivity; avoid in >125°C ambient zones. |
Compared with DRV5053OAEDBZRQ1, DRV5053PAEDBZRQ1 offers double sensitivity for improved low-field resolution while retaining identical automotive qualification and protection; DRV5055VAQDBZRQ1 trades Grade 0 temperature capability for 8× higher gain, narrowing suitability to less thermally demanding placements.

FAQ
What is the magnetic sensitivity polarity of the DRV5053OAEDBZRQ1?
The DRV5053OAEDBZRQ1 has negative sensitivity (–11 mV/mT), meaning a south pole applied to the marked side of the package reduces the output voltage below the 1 V quiescent level, while a north pole increases it. This polarity is confirmed in the device nomenclature and functional block diagram of the official datasheet SLIS154A.
Does the DRV5053OAEDBZRQ1 require an external voltage regulator?
No, the DRV5053OAEDBZRQ1 operates directly from 2.7 V to 38 V without an external regulator. Its internal regulated supply and reverse-battery protection (–22 V) allow direct connection to automotive battery rails, eliminating external LDOs or protection diodes in most implementations.
What is the maximum allowable capacitive load on the DRV5053OAEDBZRQ1 OUT pin?
The DRV5053OAEDBZRQ1 OUT pin supports a maximum capacitive load of 10 nF to maintain amplifier stability. Exceeding this value risks oscillation; if filtering is required, TI recommends using an external RC network with R ≥ 200 Ω and C ≤ 0.1 µF, as validated in the filtered typical application schematic.
How does the DRV5053OAEDBZRQ1 handle reverse supply conditions?
The DRV5053OAEDBZRQ1 survives continuous reverse supply voltages up to –22 V on the VCC pin relative to GND. During reverse bias, the device is disabled and draws negligible current; recovery occurs automatically once VCC returns to ≥2.7 V, with no latch-up or damage observed per Absolute Maximum Ratings.
Is the DRV5053OAEDBZRQ1 compatible with microcontroller ADC inputs?
Yes - the DRV5053OAEDBZRQ1 analog output (0.2–1.8 V) is fully compatible with standard 2 V or 3.3 V ADC references. To ensure accuracy, the load impedance must exceed 10 kΩ and total capacitance on OUT must remain below 10 nF, per the recommended operating conditions in section 6.3 of the datasheet.
