Product details
Overview
DRV5053VAQDBZR from Texas Instruments is a chopper-stabilized analog bipolar Hall effect sensor in SOT-23 (DBZ) package, delivering –90 mV/mT sensitivity, 0.2–1.8 V ratiometric output, and operation from 2.5 V to 38 V supply. It provides linear magnetic field response with polarity discrimination and is used in industrial position sensing where high sensitivity and thermal stability are required.
For engineers reviewing the DRV5053VAQDBZR datasheet, DRV5053VAQDBZR pinout, DRV5053VAQDBZR application, or DRV5053VAQDBZR equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade (AEC-Q100 qualified) operating range (–40°C to 125°C), real-world protection features (–22 V reverse supply, 40 V load dump), and precise alternative part comparisons for magnetic sensing design-in.
Technical Context
The DRV5053VAQDBZR implements chopper stabilization to suppress offset drift and achieve ±10% sensitivity stability over temperature. Its analog output stage delivers 300 µA source / 2.3 mA sink capability with fast 35 µs power-on time and 20 kHz bandwidth.
It operates across 2.5–38 V without external regulation, supports magnetic field polarity detection via signed output voltage (1 V at B = 0 mT), and integrates reverse supply protection, output short-circuit limiting, and transient load dump tolerance - all within a 2.92 mm × 2.37 mm surface-mount footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –90 mV/mT (typical); enables high-resolution detection of weak magnetic fields down to ~9 mT saturation limit |
| Supply Voltage Range | 2.5 V to 38 V; eliminates need for external LDO in 12/24 V industrial or automotive systems |
| Output Voltage Range | 0.2 V to 1.8 V (ratiometric); centered at 1.0 V at zero field, compatible with 3.3 V ADC reference |
| Operating Temperature | –40°C to 125°C (AEC-Q100 qualified); validated for under-hood and factory automation environments |
| Power-On Time | 35 µs (max); supports high-speed sampling in closed-loop motion control feedback |

| Protection Features | –22 V reverse supply, 40 V load dump, output short-circuit current limiting; reduces need for external protection circuitry |
Pinout & Package
DRV5053VAQDBZR uses a 3-pin SOT-23 (DBZ) package measuring 2.92 mm × 2.37 mm with standard surface-mount footprint and JEDEC Level-1 reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power input | Accepts 2.5–38 V DC; requires ≥0.01 µF ceramic bypass capacitor to GND for stability |
| GND (Pin 3) | Reference ground | Return path for supply and output; must be low-impedance to minimize noise coupling |
| OUT (Pin 2) | Analog output | Linear voltage output (0.2–1.8 V); sinks up to 2.3 mA or sources up to 300 µA into ≥10 kΩ load |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized architecture | Reduces offset drift to maintain linearity and accuracy across –40°C to 125°C ambient |
| Negative sensitivity (–90 mV/mT) | South pole near marked side pulls output below 1 V; enables intuitive polarity-based position detection |
| Integrated reverse supply protection | Withstands –22 V continuously without damage; eliminates need for external series diode in battery-reversed systems |
| Fast 35 µs power-on response | Enables duty-cycled operation in energy-sensitive applications like smart valves or portable tools |
| 20 kHz analog bandwidth | Supports real-time monitoring of dynamic magnetic events such as rotating shaft speed or vibration frequency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053RAQDBZR | –45 mV/mT sensitivity (half that of DRV5053VAQDBZR); lower output swing per mT, higher BSAT (18 mT vs 9 mT) | Better suited for larger magnetic fields or wider air gaps where full –90 mV/mT range would saturate prematurely | Select when system-level magnetic flux exceeds ±9 mT and higher linearity margin is needed over extended range |
| DRV5055VAQDBZR | Same –90 mV/mT sensitivity but with 3.3 V fixed supply (not 2.5–38 V); includes internal regulator and tighter quiescent voltage (1.0 V ±1.5%) | Requires regulated 3.3 V rail; not suitable for direct 12/24 V battery connection without external LDO | Choose only if board already has clean 3.3 V supply and tighter output voltage tolerance is critical for ADC reference matching |
Compared with DRV5053RAQDBZR and DRV5055VAQDBZR, the DRV5053VAQDBZR uniquely combines ultra-high sensitivity (–90 mV/mT), wide-input-voltage operation (2.5–38 V), and AEC-Q100 qualification - making it optimal for direct-battery-connected, high-resolution position sensing in harsh environments.

FAQ
What is the sensitivity and polarity behavior of the DRV5053VAQDBZR?
The DRV5053VAQDBZR has a nominal sensitivity of –90 mV/mT. A south pole near the marked side of the package produces a negative magnetic field, causing the output voltage to decrease below the quiescent 1.0 V level. Conversely, a north pole increases the output above 1.0 V. This polarity-aware linear response is confirmed in TI's SLIS153D datasheet Figure 7-2 and Table 6.7 for the VA variant.
Does the DRV5053VAQDBZR require an external voltage regulator?
No, the DRV5053VAQDBZR operates directly from 2.5 V to 38 V without external regulation. Its internal architecture accommodates wide-input-voltage operation, eliminating the need for an LDO or DC-DC converter in 12 V or 24 V systems. A minimum 0.01 µF ceramic bypass capacitor between VCC and GND is required per Section 5.1 of the datasheet.
What protection features does the DRV5053VAQDBZR include?
The DRV5053VAQDBZR integrates reverse supply protection up to –22 V, transient load dump tolerance up to 40 V, output short-circuit current limiting (2.3 mA sink / 300 µA source), and ESD robustness (±2500 V HBM). These protections are validated per TI's SLIS153D datasheet Sections 6.1, 6.5, and 7.3.5, reducing external component count in demanding environments.
Is the DRV5053VAQDBZR qualified for automotive applications?
Yes, the "Q" suffix in DRV5053VAQDBZR denotes AEC-Q100 qualification. It is rated for operation from –40°C to 125°C ambient temperature and meets stress test requirements for automotive use, including thermal cycling, humidity bias, and accelerated life testing. This is documented in the device nomenclature section (Figure 9-1) and Package Addendum of the datasheet.
What is the output voltage range and quiescent point of the DRV5053VAQDBZR?
The DRV5053VAQDBZR delivers an analog output from 0.2 V (negative saturation) to 1.8 V (positive saturation), with a quiescent output (B = 0 mT) of 0.9–1.15 V across –40°C to 125°C. At 25°C, typical VQ is 1.02 V. This ratiometric behavior is specified in Section 6.7 (Magnetic Characteristics) of the SLIS153D datasheet.
