Product details
Overview
DRV5056A2EDBZRQ1 from Texas Instruments is an AEC-Q100 Grade 0 automotive unipolar ratiometric linear Hall-effect sensor in SOT-23 (DBZ) package, delivering 100 mV/mT sensitivity at 5 V, 39-mT linear magnetic range, 0.6-V quiescent output, and 20-kHz bandwidth for high-accuracy position sensing in brake and throttle systems.
For engineers reviewing the DRV5056A2EDBZRQ1 datasheet, DRV5056A2EDBZRQ1 pinout, DRV5056A2EDBZRQ1 application, or DRV5056A2EDBZRQ1 equivalent, this page delivers verified technical context, exact pin functions, real-world automotive use cases, and validated alternative options - all grounded in TI's SBAS643B production data sheet.
Technical Context
The DRV5056A2EDBZRQ1 implements a fully integrated analog signal chain with on-die temperature compensation for magnet drift (STC = 0.12%/°C), ratiometric architecture that scales sensitivity linearly with VCC, and mechanical stress cancellation to maintain linearity across thermal and mechanical stress gradients.
It operates across two isolated supply ranges (3.0–3.6 V and 4.5–5.5 V), features 10 µs propagation delay, ±1-mA output drive capability, and achieves ±1% sensitivity linearity error within its 0.6 V to (VCC − 0.2 V) output voltage range - enabling direct interfacing with automotive-grade ADCs using shared VCC reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity (VCC = 5 V) | 100 mV/mT - enables precise 39-mT full-scale position detection with high SNR |
| Quiescent Output Voltage | 0.6 V ±65 mV - maximizes dynamic range for single-supply 3.3 V/5 V ADCs |
| Sensing Bandwidth | 20 kHz - supports real-time monitoring of fast-moving pedals and actuators |
| Operating Temperature | −40°C to +150°C - meets AEC-Q100 Grade 0 ambient requirements for powertrain use |
| Ratiometric Error | ±2.5% - ensures consistent digitized output when ADC shares same VCC reference |
| Magnetic Linearity Error | ±1% - guarantees sub-degree angular or sub-mm positional accuracy in calibrated systems |
| Output Drive Capability | ±1 mA - directly drives RC filters or low-input-bias ADCs without buffer amplifiers |
Pinout & Package
SOT-23 (DBZ) 3-pin surface-mount package (2.92 mm × 2.37 mm), optimized for PCB-level integration in space-constrained automotive modules. Sensing axis perpendicular to top package surface; south-pole magnetic field increases output voltage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts 3.0–3.6 V or 4.5–5.5 V; requires ≥0.1 µF ceramic decoupling capacitor to GND |
| GND | Ground reference | Return path for supply current and output current; must be low-impedance for noise immunity |
| OUT | Analog voltage output | Ratiometric output referenced to VCC; 0.6 V quiescent, scalable with B-field up to VCC − 0.2 V |
Key Features
| Feature | Design Value |
|---|---|
| Unipolar linear response | Outputs increasing voltage only for south-pole flux - eliminates ambiguity in one-direction motion sensing |
| Magnet temperature compensation | 0.12%/°C STC counteracts NdFeB magnet drift, maintaining <±1% gain error over −40°C to +150°C |
| Fast power-on time | 300 µs max tON ensures rapid system readiness after ignition or wake-up events |
| Low-noise analog output | 12 mVPP output-referred noise (A2 variant, 20 kHz BW) enables <0.1% position resolution without external filtering |
| AEC-Q100 qualification | Grade 0 temperature, HBM ±2.5 kV, CDM ±750 V - certified for under-hood and transmission control applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unipolar linear Hall-effect sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5055A2QLPGMQ1 | TO-92 package only; identical A2 sensitivity (100 mV/mT) but 121°C/W θJA vs 170°C/W for DBZ | Preferred for through-hole assembly or higher thermal mass mounting; lower thermal resistance improves stability in sealed housings | Select when board layout requires axial leaded mounting or thermal dissipation exceeds SOT-23 limits |
| TMAG5170A2QDGKRQ1 | 3-axis digital SPI output; 100 mT full-scale per axis; no analog ratiometric output | Used in multi-axis angle/torque sensing where vector field decomposition is required, not scalar position | Choose only when system needs directional field data or digital interface - not a drop-in replacement for analog output |
Compared with DRV5056A2EDBZRQ1, DRV5055A2QLPGMQ1 offers identical magnetic performance in a thermally superior through-hole package, while TMAG5170A2QDGKRQ1 shifts to digital 3D sensing - making the former a true functional alternative and the latter a system-architecture upgrade.

FAQ
What is the exact sensitivity and linear range of DRV5056A2EDBZRQ1 at 5 V?
The DRV5056A2EDBZRQ1 has a nominal sensitivity of 100 mV/mT and a linear magnetic sensing range of 39 mT when operated at VCC = 5 V and TA = 25°C. This is confirmed in Section 5.6 of TI's SBAS643B datasheet, where BL (linear range) is specified as 39 mT for the A2 variant under those conditions. The device maintains ±1% linearity error within this range.
Does DRV5056A2EDBZRQ1 support both 3.3 V and 5 V supplies, and how does ratiometry work?
Yes, DRV5056A2EDBZRQ1 operates across two recommended VCC ranges: 3.0–3.6 V and 4.5–5.5 V. Its ratiometric architecture scales sensitivity linearly with VCC - e.g., sensitivity increases ~5% when VCC rises from 5 V to 5.25 V. When the external ADC uses the same VCC as its reference, this cancels supply tolerance errors in digitized output, as documented in Section 6.3.4 of the DRV5056A2EDBZRQ1 datasheet.
What is the quiescent output voltage of DRV5056A2EDBZRQ1, and why is it set to 0.6 V?
The DRV5056A2EDBZRQ1 has a typical quiescent output voltage (VQ) of 0.6 V at B = 0 mT and TA = 25°C, with a min/max range of 0.54 V to 0.66 V. This value is intentionally centered to maximize usable output swing - allowing up to (VCC − 0.2 V) for positive B-field response while retaining headroom for noise margin and ADC input range, as defined in Section 5.6 of the official datasheet.
How does DRV5056A2EDBZRQ1 compensate for magnet temperature drift?
DRV5056A2EDBZRQ1 applies sensitivity temperature compensation (STC) at 0.12%/°C to counteract the intrinsic flux loss of neodymium magnets with rising temperature. This compensation increases device sensitivity proportionally, maintaining stable gain across −40°C to +150°C ambient. Section 6.3.6 confirms this design targets NdFeB magnets and partially compensates ferrite types.
Is DRV5056A2EDBZRQ1 pin-compatible with other variants in the DRV5056-Q1 family?
Yes, all DRV5056-Q1 variants - including DRV5056A1EDBZRQ1, DRV5056A2EDBZRQ1, DRV5056A3EDBZRQ1, and DRV5056A4EDBZRQ1 - share identical SOT-23 (DBZ) pinout, package dimensions, and electrical interface. Only sensitivity and linear range differ; no PCB redesign is needed when upgrading or downgrading between A1–A4 versions.
