Product details
Overview
DRV5053RAQLPGMQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive analog bipolar Hall effect sensor in TO-92 (LPG) package, delivering –45 mV/mT sensitivity, 0.2–1.8 V ratiometric output, ±10% sensitivity stability over –40°C to +125°C, and reverse supply protection to –22 V. It serves as a linear magnetic field transducer in damper control systems where precise analog position feedback under harsh automotive conditions is required.
For engineers reviewing the DRV5053RAQLPGMQ1 datasheet, DRV5053RAQLPGMQ1 pinout, DRV5053RAQLPGMQ1 application, or DRV5053RAQLPGMQ1 equivalent, key selection criteria include its –45 mV/mT high-sensitivity bipolar response, 35 µs power-on time, 20 kHz bandwidth, 0.9–1.15 V quiescent output at B = 0 mT, and TO-92 mechanical compatibility with through-hole mounting in space-constrained chassis modules.
Technical Context
The DRV5053RAQLPGMQ1 implements chopper-stabilized Hall sensing architecture to suppress offset drift and achieve ±10% sensitivity stability across temperature. Its analog output stage provides 300 µA sourcing and 2.3 mA sinking capability with internal protection against load dump (up to 40 V), reverse supply (–22 V), and output short-circuit.
This variant uses a negative sensitivity polarity (–45 mV/mT), meaning a south pole near the marked side of the TO-92 package reduces output voltage below 1 V, while a north pole increases it-enabling bidirectional field detection without external signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –45 mV/mT: Output changes –45 mV per millitesla change in perpendicular magnetic field; enables high-resolution analog position sensing at low field strengths. |
| Output Range | 0.2 V to 1.8 V: Full-scale analog swing accommodates standard 2.0 V ADC reference rails; 1.0 V quiescent point (B = 0 mT) provides symmetrical headroom for ± field detection. |
| Supply Voltage | 2.7 V to 38 V: Direct connection to automotive battery (12 V nominal) or start-stop systems without external regulation; supports cold-crank down to 2.7 V. |
| Power-On Time | 35 µs typical: Enables fast system wake-up and real-time magnetic event capture in safety-critical damping or vibration correction loops. |
| Bandwidth | 20 kHz: Supports dynamic field tracking up to 20,000 Hz-sufficient for engine-speed-related vibration monitoring and active suspension control signals. |
| Operating Temp | –40°C to +125°C (Grade 1): Validated for under-hood placement in passenger vehicles per AEC-Q100 requirements; junction temperature limited by TO-92 thermal resistance (RθJA = 180°C/W). |
| Input Noise | 0.49 mTpp typical: Low magnetic noise floor ensures stable analog output in electrically noisy engine compartments without requiring additional filtering. |
Pinout & Package
DRV5053RAQLPGMQ1 uses the 3-pin TO-92 (LPG) through-hole package (4.00 mm × 3.15 mm body), optimized for mechanical robustness and thermal dissipation in chassis-mounted applications. The package features a marked side indicating Hall element orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power input | Accepts 2.7–38 V DC; requires ≥0.01 µF ceramic bypass capacitor to GND; reverse-protected to –22 V. |
| GND (Pin 2) | Reference ground | System return path for supply and output; must be low-impedance to minimize noise coupling into analog output. |
| OUT (Pin 3) | Analog output | 0.2–1.8 V linear voltage proportional to magnetic flux density; sinks up to 2.3 mA or sources up to 300 µA; load impedance >10 kΩ required. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces inherent Hall element offset drift to enable <±1% linearity error over temperature and lifetime-critical for calibrated damper position reporting. |
| Bipolar linear output | –45 mV/mT sensitivity with 1 V quiescent point allows direct detection of both north and south pole proximity using a single analog channel and no external inversion circuitry. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40°C to +125°C ambient, including thermal cycling, humidity, and vibration tests-ensuring reliability in powertrain and chassis modules. |
| Integrated protection | Reverse supply (–22 V), load dump (40 V transient), output short-circuit, and overcurrent limiting eliminate need for external TVS diodes or current-limiting resistors in production designs. |
| Fast power-on response | 35 µs turn-on time enables immediate magnetic sampling after microcontroller wake-up-supporting low-power duty-cycled sensing in battery-operated docking systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog bipolar Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053PAQLPGMQ1 | –23 mV/mT sensitivity (≈51% lower gain); higher BSAT (35 mT vs. 18 mT); lower output noise (0.49 mTpp → 0.40 mTpp). | Better suited for higher-field environments (e.g., motor stator gap sensing) but requires larger magnets or closer spacing for same output swing. | Select when field strength exceeds 25 mT and lower noise is prioritized over resolution; not drop-in due to reduced gain affecting ADC scaling. |
| DRV5053EAQLPGMQ1 | +45 mV/mT sensitivity (same magnitude, opposite polarity); identical quiescent voltage, bandwidth, and protection specs. | Requires reversed magnet orientation (south pole decreases output) or inverted signal processing in firmware. | Choose for applications where positive-slope response simplifies analog signal chain or matches legacy design conventions; pinout and layout identical. |
Compared with DRV5053PAQLPGMQ1, the DRV5053RAQLPGMQ1 delivers higher resolution at low fields but saturates earlier; compared with DRV5053EAQLPGMQ1, it offers identical performance except for magnetic polarity mapping-requiring only magnet reorientation or firmware sign inversion.

FAQ
What is the exact sensitivity and polarity of DRV5053RAQLPGMQ1?
The DRV5053RAQLPGMQ1 has a nominal sensitivity of –45 mV/mT, meaning its output voltage decreases by 45 mV per millitesla increase in magnetic flux density applied perpendicular to the marked side of the TO-92 package. A south pole near that side produces a negative field (B > 0), lowering the output below 1 V; a north pole raises it. This polarity is confirmed in TI's SLIS154A datasheet Section 7.1 and Figure 8.
Does DRV5053RAQLPGMQ1 require an external voltage regulator?
No, DRV5053RAQLPGMQ1 operates directly from 2.7 V to 38 V supply without external regulation. Its internal regulated supply handles wide-input variations, and reverse supply protection up to –22 V eliminates need for external polarity protection diodes-reducing BOM count and PCB area in automotive battery-connected designs.
What is the maximum magnetic field the DRV5053RAQLPGMQ1 can measure before saturation?
The DRV5053RAQLPGMQ1 saturates at ±18 mT (BSAT), beyond which output clamps at 0.2 V (negative saturation) or 1.8 V (positive saturation). This is specified in the Magnetic Characteristics table for the RA variant (SLIS154A, Section 6.7) and reflects its high-sensitivity design-optimized for precision measurement within this range rather than high-field tolerance.
Can DRV5053RAQLPGMQ1 be used in AEC-Q100 Grade 0 (–40°C to +150°C) applications?
No, DRV5053RAQLPGMQ1 is qualified only for AEC-Q100 Grade 1 (–40°C to +125°C ambient). Its marking suffix "Q" denotes Grade 1; Grade 0 variants (e.g., DRV5053RAELPGMQ1) use "E" suffix and are rated to +150°C. Using DRV5053RAQLPGMQ1 above 125°C ambient violates qualification limits and may cause parametric shift or premature failure.
What is the recommended output load for DRV5053RAQLPGMQ1?
DRV5053RAQLPGMQ1 requires an output load impedance >10 kΩ to ensure proper operation, as specified in Section 7.3.4 of the datasheet. Lower loads risk output stage instability or inaccurate voltage levels. For ADC interfacing, ensure the input impedance of the microcontroller's analog pin meets this requirement-or add a unity-gain buffer if necessary.
