Product details
Overview
DRV5053RAEDBZRQ1 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 –45 mV/mT sensitivity, 0.2–1.8 V ratiometric output, ±10% sensitivity stability over –40°C to +150°C, and 20 kHz bandwidth for precise magnetic field measurement in damper controls and flow meters.
For engineers reviewing the DRV5053RAEDBZRQ1 datasheet, DRV5053RAEDBZRQ1 pinout, DRV5053RAEDBZRQ1 application, or DRV5053RAEDBZRQ1 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, automotive-qualified protection features, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The DRV5053RAEDBZRQ1 implements chopper-stabilized Hall sensing architecture to suppress offset drift, enabling stable analog output voltage proportional to perpendicular magnetic flux density (B). Its internal regulated supply and temperature-compensated amplifier maintain linearity across –40°C to +150°C ambient.
It operates from 2.7 V to 38 V DC supply with reverse polarity protection up to –22 V, supports 300 µA source / 2.3 mA sink output drive, and features fast 35 µs power-on time - critical for engine-critical automotive subsystems requiring deterministic startup behavior.
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; spans full 0–2 V analog window with 1 V quiescent point at B = 0 mT for bidirectional field polarity discrimination |
| Bandwidth | 20 kHz; supports real-time monitoring of rapidly varying fields such as vibration-induced motion or rotating shaft position |
| Supply Range | 2.7 V to 38 V; eliminates need for external LDO in 12 V/24 V automotive systems including load-dump transients up to 40 V |
| Operating Temp | –40°C to +150°C (Grade 0); qualified for under-hood applications like transmission sensors and exhaust gas recirculation valves |
| Input Noise | 0.49 mTpp (typical); ensures sub-millitesla resolution without external filtering in low-speed position sensing |
| Power-On Time | 35 µs (typical); guarantees valid output within one microcontroller ADC sampling cycle after ignition power-up |
Pinout & Package
DRV5053RAEDBZRQ1 uses a surface-mount 3-pin SOT-23 (DBZ) package measuring 2.92 mm × 2.37 mm × 1.30 mm, optimized for automated assembly and space-constrained automotive PCBs.
| 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 for noise immunity and stability |
| OUT (Pin 2) | Analog output | 0.2–1.8 V linear voltage output referenced to GND; sinks up to 2.3 mA or sources up to 300 µA |
| GND (Pin 3) | Ground reference | System return path for both power and signal; must be low-impedance to minimize offset error and EMI coupling |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces thermal drift and 1/f noise, maintaining ±10% sensitivity accuracy over full –40°C to +150°C range |
| Reverse supply protection | Withstands –22 V continuously on VCC without latch-up or damage - essential for battery-reversal fault tolerance |
| Load dump resilience | Operates up to 38 V DC and survives 40 V transients per ISO 7637-2 without external clamping components |
| Output short-circuit protection | Internally limits sink current to 2.3 mA and source current to 300 µA, preventing thermal runaway during wiring faults |
| Small footprint | 2.92 mm × 2.37 mm SOT-23 package enables placement directly behind metal housings or near rotating targets with minimal air gap |
Applications
| Flow Meters | Damper Controls |
|---|---|
Use Scenario: Measuring fluid velocity in HVAC or fuel lines via turbine rotation or paddle-wheel displacement. IC Role / Device Role / Timing Role: Linear Hall sensor detecting magnet position on rotating element to generate proportional analog voltage for microcontroller ADC conversion.

IC Role / Device Role / Timing Role: Bidirectional field polarity detection distinguishes open/closed states and intermediate positions of magnet-coupled damper shafts. Use Value: 0.2–1.8 V output swing maps linearly to 0–100% damper travel, eliminating need for lookup tables or digital interpolation in closed-loop feedback. |
| Vibration Correction | Docking Adjustment |
Use Scenario: Detecting resonant frequency and amplitude of vibrating machinery components for active damping compensation. IC Role / Device Role / Timing Role: High-bandwidth (20 kHz) analog output captures rapid field fluctuations induced by mechanical oscillation near mounted magnets.

IC Role / Device Role / Timing Role: Analog voltage output tracks magnet proximity during fine-positioning, providing continuous feedback before physical contact. Use Value: 35 µs power-on time ensures immediate readiness upon system wake-up, supporting sub-100 ms docking cycle times in safety-critical automation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053EAEDBZRQ1 | +45 mV/mT sensitivity (positive polarity); identical package, temp grade, and protection features | Requires reversed magnet orientation (south pole induces voltage rise) - unsuitable for existing RA-based PCB layouts without mechanical rework | Select when system design permits magnet polarity inversion and benefits from positive-slope output scaling with microcontroller ADC reference |
| MLX90242ESE-AAA-025-SP | ±25 mV/mT sensitivity; 3.3 V only supply; TO-92 package; no reverse-voltage or load-dump protection | Lacks automotive-grade transient protection and wide-input capability - limited to low-voltage consumer or industrial non-safety-critical use | Consider only for cost-sensitive, non-automotive applications where 2.7–38 V operation and –22 V reverse tolerance are not required |
Compared with DRV5053RAEDBZRQ1, DRV5053EAEDBZRQ1 offers identical robustness but inverted polarity response, while MLX90242ESE-AAA-025-SP trades automotive qualification and supply flexibility for lower unit cost in benign environments.

FAQ
What is the operating temperature range for DRV5053RAEDBZRQ1?
DRV5053RAEDBZRQ1 is rated for –40°C to +150°C ambient operation (AEC-Q100 Grade 0), validated for under-hood automotive applications including transmission control modules and exhaust valve actuators. This range is guaranteed with ±10% sensitivity stability and full functionality across the entire span, as confirmed in TI's SLIS154A datasheet Section 6.3.
Does DRV5053RAEDBZRQ1 require an external voltage regulator?
No, DRV5053RAEDBZRQ1 does not require an external voltage regulator. It operates directly from 2.7 V to 38 V DC supply rails, incorporating internal regulation that maintains stable biasing and output performance across this full range - including during 40 V load-dump transients per ISO 7637-2, as specified in Section 6.1 and 6.3 of the datasheet.
What is the magnetic sensitivity polarity of DRV5053RAEDBZRQ1?
DRV5053RAEDBZRQ1 has negative sensitivity (–45 mV/mT), meaning a south pole near the marked side of the SOT-23 package causes the output voltage to decrease below 1 V, while a north pole causes it to increase above 1 V. This polarity is fixed per device variant and defined in Section 7.1 and Figure 8 of the SLIS154A datasheet.
Can DRV5053RAEDBZRQ1 survive reverse battery connection?
Yes, DRV5053RAEDBZRQ1 survives reverse battery conditions up to –22 V applied continuously between VCC and GND, as stated in Absolute Maximum Ratings (Section 6.1) and Feature Description (Section 7.3.5.3). During reverse supply, the device is disabled but remains undamaged and resumes normal operation once VCC returns to ≥2.7 V.
What is the recommended bypass capacitor for DRV5053RAEDBZRQ1?
The recommended bypass capacitor for DRV5053RAEDBZRQ1 is a minimum 0.01 µF ceramic capacitor placed between VCC (Pin 1) and GND (Pin 3), rated for the full 38 V supply voltage. This value is specified in Pin Functions (Section 5), Typical Application schematics (Figure 12), and Power Supply Recommendations (Section 9) of the SLIS154A datasheet.
