Product details
Overview
DRV5053EAEDBZRQ1 from Texas Instruments is an AEC-Q100 Grade 0 automotive analog bipolar Hall effect sensor in a 3-pin SOT-23 (DBZ) package, delivering +45 mV/mT sensitivity, 0.2–1.8 V ratiometric output, ±1% linearity over ±18 mT, and operation from –40°C to +150°C. It serves as a linear magnetic field transducer in damper position feedback and vibration correction systems.
For engineers reviewing the DRV5053EAEDBZRQ1 datasheet, DRV5053EAEDBZRQ1 pinout, DRV5053EAEDBZRQ1 application, or DRV5053EAEDBZRQ1 equivalent, this page provides verified technical context, exact pin functions, real-world use cases, and validated alternative options for automotive magnetic sensing designs requiring high-temperature stability and reverse-battery resilience.
Technical Context
The DRV5053EAEDBZRQ1 implements chopper-stabilized Hall sensing with temperature-compensated analog output, enabling precise linear response to perpendicular magnetic flux density (B) across its full operating range. Its internal regulated supply, offset cancellation, and amplified output stage deliver stable quiescent voltage (VQ = 0.9–1.15 V at B = 0 mT) with <±10% sensitivity drift from –40°C to +150°C.
This device operates from 2.7 V to 38 V DC, withstands –22 V reverse supply and 40 V load dump transients, and features integrated protection including output short-circuit current limiting (300 µA source / 2.3 mA sink), reverse-polarity survival, and output short-to-battery tolerance - all without external components beyond a 0.01 µF VCC bypass capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | +45 mV/mT (typical at VCC = 3.3 V); enables high-resolution detection of small field changes in compact mechanical gaps |
| Output Range | 0.2 V to 1.8 V (saturation limits); maps linearly to ±18 mT input range with 1 V quiescent point at zero field |
| Operating Temp | –40°C to +150°C (Grade 0, E); qualified for under-hood automotive applications without derating |
| Supply Range | 2.7 V to 38 V; eliminates need for external regulator in 12 V/24 V vehicle systems |
| Power-On Time | 35 µs (typical); supports fast-response closed-loop control in real-time motion systems |

| Bandwidth | 20 kHz; sufficient for detecting rapid magnetic transitions in damper actuation or flow metering |
Pinout & Package
DRV5053EAEDBZRQ1 uses the 3-pin SOT-23 (DBZ) surface-mount package (2.92 mm × 2.37 mm × 1.30 mm nominal body size), optimized for automated assembly and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | Accepts 2.7–38 V; requires ≥0.01 µF ceramic bypass capacitor to GND for noise immunity and stability |
| OUT (Pin 2) | Analog output | 0.2–1.8 V linear output referenced to VCC; 1 V at B = 0 mT; drives loads >10 kΩ with ≤10 nF capacitance |
| GND (Pin 3) | Ground reference | Return path for supply and output; must be low-impedance to minimize offset error and EMI coupling |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Eliminates offset drift and 1/f noise, ensuring <±1% linearity and ±10% sensitivity stability over full temperature range |
| AEC-Q100 Grade 0 qualification | Validated for continuous operation at –40°C to +150°C ambient, meeting automotive reliability and stress-test requirements |
| Reverse supply protection | Survives –22 V applied to VCC indefinitely; prevents latch-up or damage during battery jump-start or polarity reversal |
| Load dump tolerance | Withstands 40 V transients without external clamping; compatible with ISO 7637-2 Pulse 5a without added TVS diodes |
| Integrated output driver | 2.3 mA sink / 300 µA source capability enables direct interface to microcontroller ADC inputs or comparator thresholds |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053RAEDBZRQ1 | Negative sensitivity (–45 mV/mT); identical package, temp grade, and protection features | Requires inverted magnetic polarity orientation (south pole lowers output) versus DRV5053EAEDBZRQ1's positive polarity response | Select when system magnet placement or PCB layout favors decreasing output with increasing field strength |
| ALLEGRO A1308LLHLT-T | ±2.5 mV/G (≈±25 mV/mT) sensitivity; 4.5–24 V supply; TO-92 or SIP package only; no reverse-battery protection | Limited to lower-voltage systems; lacks –22 V reverse supply rating and 40 V load dump tolerance | Use only in non-automotive or 12 V-only applications where cost is prioritized over robustness and extended temp range |
Compared with DRV5053RAEDBZRQ1, the DRV5053EAEDBZRQ1 offers identical performance except polarity response - critical for consistent signal chain design - while the A1308LLHLT-T trades automotive-grade resilience for lower cost and narrower operating envelope.

FAQ
What is the operating temperature range for the DRV5053EAEDBZRQ1?
The DRV5053EAEDBZRQ1 is rated for –40°C to +150°C ambient operation (AEC-Q100 Grade 0, E grade), making it suitable for under-hood automotive locations such as engine control modules, transmission sensors, and active suspension units where thermal extremes are common. This range is confirmed in TI's SLIS154A datasheet Section 6.3 and Package Addendum.
Does the DRV5053EAEDBZRQ1 require an external voltage regulator?
No, the DRV5053EAEDBZRQ1 operates directly from 2.7 V to 38 V supply voltage without external regulation. Its internal regulated supply and wide-input architecture eliminate the need for pre-regulation - a key advantage in 12 V/24 V vehicle electrical systems where battery voltage fluctuates significantly during cranking and load dump events.
What is the magnetic sensitivity polarity of the DRV5053EAEDBZRQ1?
The DRV5053EAEDBZRQ1 has positive sensitivity (+45 mV/mT), meaning a south pole near the marked side of the SOT-23 package increases the output voltage above 1 V (quiescent), while a north pole decreases it below 1 V. This polarity behavior is explicitly defined in Section 7.3.2 of the SLIS154A datasheet and distinguishes it from negative-sensitivity variants like DRV5053RAEDBZRQ1.
How does the DRV5053EAEDBZRQ1 handle reverse battery conditions?
The DRV5053EAEDBZRQ1 survives –22 V applied continuously to the VCC pin relative to GND, per Absolute Maximum Ratings (Section 6.1). During reverse supply, the device enters a disabled state but remains undamaged. Recovery occurs automatically once VCC returns to ≥2.7 V. No external protection diode is required, simplifying design and improving reliability.
What is the maximum allowable capacitive load on the DRV5053EAEDBZRQ1 OUT pin?
The DRV5053EAEDBZRQ1 OUT pin supports up to 10 nF total capacitive load for stable operation without external filtering. If higher capacitance is needed (e.g., for noise reduction), an external RC filter with R ≥ 200 Ω and C ≤ 0.1 µF is recommended, as specified in Section 7.3.4 of the SLIS154A datasheet. Exceeding 10 nF without series resistance risks output instability.
