Product details
Overview
DRV5053VAEDBZRQ1 from Texas Instruments is an AEC-Q100 Grade 0 automotive-grade linear analog bipolar Hall effect sensor in a 3-pin SOT-23 (DBZ) package, delivering –90 mV/mT sensitivity, 0.2–1.8 V ratiometric output, ±10% sensitivity stability over –40°C to +150°C, and reverse supply protection to –22 V - used for precise magnetic field polarity and magnitude sensing in damper position feedback and flow metering.
For engineers reviewing the DRV5053VAEDBZRQ1 datasheet, DRV5053VAEDBZRQ1 pinout, DRV5053VAEDBZRQ1 application, or DRV5053VAEDBZRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed magnetic and electrical specifications, real-world automotive use cases, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The DRV5053VAEDBZRQ1 implements chopper-stabilized Hall sensing architecture to suppress offset drift, enabling stable analog output linearity (≤1%) across its full magnetic range. Its internal regulated supply and temperature-compensated amplifier deliver consistent –90 mV/mT sensitivity at 3.3 V with input-referred noise of 0.40–0.79 mTpp.
It operates from 2.7 V to 38 V with fast 35 µs power-on time, features a 20 kHz bandwidth, and integrates protection against reverse supply (–22 V), load dump (40 V transient), output short-circuit, and overcurrent - all without external components beyond a 0.01 µF bypass capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –90 mV/mT (typical at VCC = 3.3 V); enables high-resolution detection of small magnetic field changes in compact mechanical gaps. |
| Output Range | 0.2 V to 1.8 V; spans full rail-to-rail usable analog window with 1.0 V quiescent point at B = 0 mT. |
| Operating Temp | –40°C to +150°C (Grade 0); qualified for under-hood automotive applications including engine control and transmission sensors. |
| Supply Range | 2.7 V to 38 V; eliminates need for external voltage regulator in 12 V/24 V vehicle systems. |
| Power-On Time | 35 µs (typical); supports high-speed closed-loop control in real-time motion feedback systems. |
| Bandwidth | 20 kHz; sufficient for dynamic sensing in vibration correction and rotating shaft monitoring. |
| Input Noise | 0.40–0.79 mTpp; defines minimum detectable field change in low-amplitude applications like docking alignment. |
Pinout & Package
DRV5053VAEDBZRQ1 uses a surface-mount 3-pin SOT-23 (DBZ) package measuring 2.92 mm × 2.37 mm × 1.30 mm, optimized for space-constrained automotive PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | Accepts 2.7–38 V DC; requires ≥0.01 µF ceramic bypass capacitor to GND for stable operation. |
| GND (Pin 3) | Ground reference | System return path for both supply and analog output; must be low-impedance for noise immunity. |
| OUT (Pin 2) | Analog output | Linear 0.2–1.8 V voltage proportional to perpendicular magnetic flux density; sinks up to 2.3 mA or sources up to 300 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces thermal drift and offset error, ensuring ≤±10% sensitivity variation across –40°C to +150°C. |
| AEC-Q100 Grade 0 qualification | Validated for automotive use at junction temperatures up to +175°C, supporting engine bay and transmission environments. |
| Integrated reverse polarity protection | Withstands –22 V applied to VCC continuously without damage - eliminates need for external diode in battery-reversal-prone systems. |
| Load dump tolerance | Survives 40 V transients per ISO 7637-2 without external clamping, simplifying front-end protection design. |
| Output short-circuit protection | Clamps sink current at 2.3 mA and source current at 300 µA, preventing latch-up or thermal runaway during fault conditions. |
Applications
| Flow Meters | Docking Adjustment |
|---|---|
Use Scenario: Measuring fluid velocity via turbine rotation or paddle-wheel displacement in fuel, coolant, or HVAC systems. IC Role / Device Role / Timing Role: Linear Hall sensor detecting magnet position on rotating element to generate analog voltage proportional to flow rate. Use Value: High sensitivity (–90 mV/mT) resolves sub-degree angular changes, enabling <1% full-scale accuracy in analog flow calibration. |
Use Scenario: Precise alignment feedback during robotic arm docking or modular connector mating in ADAS and infotainment modules. IC Role / Device Role / Timing Role: Detecting proximity and polarity of mating magnets to confirm mechanical engagement before signal handoff.

Use Scenario: Position feedback for electronically controlled shock absorbers in premium vehicle suspensions. IC Role / Device Role / Timing Role: Analog linear output directly interfaces with MCU ADC to determine damper extension/compression state. Use Value: Ratiometric 0.2–1.8 V output maintains accuracy across wide supply fluctuations (2.7–38 V), critical in start-stop and load-dump scenarios. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall effect sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5055VAQDBZRQ1 | Higher sensitivity (–100 mV/mT), wider operating range (–40°C to +125°C), same DBZ package and pinout. | Optimized for lower-field environments (e.g., pedal position sensing); lacks Grade 0 temp rating for under-hood use. | Select when higher resolution is needed below ±10 mT and ambient temperature stays ≤125°C. |
| MLX90242ESE-ABA-000-TU | Tri-axis analog output, ±20 mT range, 3.3 V only, SOIC-8 package; no reverse-voltage or load-dump protection. | Requires external protection circuitry and voltage regulation; suited for non-automotive industrial encoders or joysticks. | Choose only if multi-axis field vector measurement is required and system-level protection can be added. |
Compared with DRV5053VAEDBZRQ1, DRV5055VAQDBZRQ1 offers finer resolution but reduced thermal margin, while MLX90242ESE-ABA-000-TU adds spatial sensing capability at the cost of automotive robustness and single-supply simplicity.

FAQ
What is the operating temperature range for DRV5053VAEDBZRQ1?
DRV5053VAEDBZRQ1 is rated for –40°C to +150°C ambient operation (AEC-Q100 Grade 0), with junction temperature support up to +175°C. This makes it suitable for under-hood applications such as transmission speed sensing and engine valve timing where thermal stress is extreme. The device maintains ±10% sensitivity stability across this full range due to integrated chopper stabilization and temperature compensation.
Does DRV5053VAEDBZRQ1 require external protection components?
No - DRV5053VAEDBZRQ1 integrates reverse supply protection (up to –22 V), load dump tolerance (40 V transient), output short-circuit clamping, and overcurrent limiting. Only a 0.01 µF ceramic bypass capacitor between VCC and GND is required for stable operation. No external TVS diodes, series resistors, or regulators are needed, reducing BOM count and PCB area.
How does the sensitivity of DRV5053VAEDBZRQ1 compare to other variants in the DRV5053-Q1 family?
DRV5053VAEDBZRQ1 has the highest negative sensitivity in the family at –90 mV/mT (typical), double that of the RA variant (–45 mV/mT) and four times the OA variant (–11 mV/mT). This enables detection of smaller magnetic fields or greater air gaps in mechanical assemblies, making it ideal for applications like fine-position damper feedback where resolution is critical.
What is the output behavior of DRV5053VAEDBZRQ1 at zero magnetic field?
At B = 0 mT, DRV5053VAEDBZRQ1 outputs a quiescent voltage (VQ) of 0.9–1.15 V (typical 1.0 V), independent of supply voltage within 2.7–38 V. This ratiometric center point allows direct interfacing with 12-bit or higher MCU ADCs without gain/offset calibration, and polarity of applied field determines whether output rises (north pole) or falls (south pole) from this baseline.
Can DRV5053VAEDBZRQ1 be used in systems with 24 V nominal supply?
Yes - DRV5053VAEDBZRQ1 supports 2.7 V to 38 V DC operation, fully covering 12 V and 24 V automotive battery systems, including cranking dips and load dump surges. Its internal protection circuits eliminate the need for external voltage clamping, and its 35 µs power-on time ensures rapid response after ignition startup or wake-from-sleep events.
