Product details
Overview
DRV5053EAQDBZRQ1 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, and operation from –40°C to +150°C. It provides linear magnetic field sensing for position and motion detection in harsh environments such as damper controls and flow meters.
For engineers reviewing the DRV5053EAQDBZRQ1 datasheet, DRV5053EAQDBZRQ1 pinout, DRV5053EAQDBZRQ1 application, or DRV5053EAQDBZRQ1 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The DRV5053EAQDBZRQ1 uses chopper-stabilized Hall sensing architecture to achieve ±1% linearity over ±18 mT input range and ±10% sensitivity stability across 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 from 2.7 V to 38 V supply, includes reverse supply protection up to –22 V, load dump tolerance to 40 V, and short-circuit protection on the OUT pin - all without external regulators or discrete protection components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | +45 mV/mT (typical at VCC = 3.3 V); enables high-resolution detection of weak magnetic fields in compact mechanical gaps. |
| Output Range | 0.2 V to 1.8 V; spans full 0–2 V rail with 1 V quiescent point at B = 0 mT, compatible with 3.3 V ADC reference inputs. |
| Operating Temp | –40°C to +150°C (Grade 0); qualified for under-hood automotive applications including engine control and transmission sensors. |
| Supply Voltage | 2.7 V to 38 V; eliminates need for external LDO in 12 V/24 V vehicle systems and supports wide battery voltage transients. |
| Power-On Time | 35 µs (typical); ensures rapid system readiness after ignition or wake-up events in safety-critical timing loops. |
| Input Saturation | ±18 mT (BSAT); defines usable linear range before output saturates - critical for selecting magnet strength and air gap. |
| Output Noise | 22 mVpp (typical, VCC = 3.3 V); determines minimum detectable field change (~0.5 mT RMS) in unfiltered configurations. |
Pinout & Package
DRV5053EAQDBZRQ1 uses a 3-pin SOT-23 (DBZ) surface-mount package measuring 2.92 mm × 2.37 mm × 1.30 mm, optimized for automated assembly and space-constrained PCB layouts in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | Accepts 2.7–38 V DC; requires ≥0.01 µF ceramic bypass capacitor to GND for noise immunity and stability. |
| GND (Pin 3) | Ground reference | Return path for supply current and output stage; must be low-impedance to minimize offset drift and EMI coupling. |
| OUT (Pin 2) | Analog output | 0.2–1.8 V linear voltage proportional to perpendicular magnetic flux density; drives loads >10 kΩ with <10 nF capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces offset drift to <±1% over temperature, enabling stable zero-field calibration without trimming. |
| AEC-Q100 Grade 0 | Qualified for continuous operation at 150°C ambient - suitable for engine bay, transmission, and brake module placement. |
| Reverse supply protection | Withstands –22 V on VCC indefinitely; eliminates need for external series diode in battery-reversal-prone installations. |
| Integrated OCP | Clamps output current to 300 µA (source) or 2.3 mA (sink), preventing latch-up during short-to-rail faults. |
| Load dump tolerance | Survives 40 V transients per ISO 7637-2 Pulse 5a without external TVS - reduces BOM count in 24 V commercial vehicle designs. |
Applications
| Flow Meters | Damper Controls |
|---|---|
Use Scenario: Detecting rotational speed of turbine blades or gear teeth in fuel, coolant, or HVAC fluid lines. IC Role / Device Role / Timing Role: Analog Hall sensor converting magnetic pole transitions into linear voltage pulses for microcontroller ADC sampling.

IC Role / Device Role / Timing Role: Contactless proximity detector providing analog position feedback prior to physical engagement. Use Value: 0.2–1.8 V output range maps directly to 12-bit ADC full scale, enabling sub-0.1 mm resolution with standard MCU peripherals - no external signal conditioning required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5053RAQDBZRQ1 | Negative sensitivity (–45 mV/mT); identical package, temp grade, and electrical specs except polarity inversion. | Required where south-pole proximity must drive output below 1 V (e.g., legacy interface compatibility). | Select when magnetic orientation or existing firmware expects inverse voltage vs. field polarity mapping. |
| DRV5055VAQDBZRQ1 | Digital PWM output (not analog); 10-bit resolution, 20 kHz update rate, same supply range and AEC-Q100 Grade 0 rating. | Suitable for direct microcontroller GPIO input without ADC; less susceptible to analog noise but lacks fine-grained field interpolation. | Choose for simplified digital interfacing, deterministic timing, or when analog noise immunity is insufficient in high-EMI zones. |
Compared with DRV5053EAQDBZRQ1, DRV5053RAQDBZRQ1 offers identical analog performance with inverted polarity - ideal for backward-compatible redesigns - while DRV5055VAQDBZRQ1 replaces analog voltage output with robust PWM, trading resolution for noise resilience and eliminating ADC dependency.

FAQ
What is the operating temperature range of the DRV5053EAQDBZRQ1?
The DRV5053EAQDBZRQ1 is rated for –40°C to +150°C ambient operation (AEC-Q100 Grade 0). This range is validated per TI's qualification testing and supports under-hood deployment in engines, transmissions, and brake modules where sustained high temperatures occur. The device maintains specified sensitivity and output linearity across this full range, with no derating required.
Does the DRV5053EAQDBZRQ1 require an external voltage regulator?
No, the DRV5053EAQDBZRQ1 does not require an external voltage regulator. It operates directly from 2.7 V to 38 V supply rails, covering nominal 12 V and 24 V automotive batteries plus transient conditions. Internal regulation ensures stable biasing of the Hall element and amplifier - only a 0.01 µF ceramic bypass capacitor between VCC and GND is required for noise suppression.
What is the magnetic polarity response of the DRV5053EAQDBZRQ1?
The DRV5053EAQDBZRQ1 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 definition is fixed by TI's package marking convention and is consistent across all EA-suffix variants.
Can the DRV5053EAQDBZRQ1 withstand automotive load dump events?
Yes, the DRV5053EAQDBZRQ1 withstands load dump transients up to 40 V for short durations per ISO 7637-2 Pulse 5a, without external protection. This is enabled by internal clamp circuitry and is validated in TI's production testing. No series resistor or TVS diode is needed for compliance in standard 12 V or 24 V vehicle architectures.
What is the recommended output load for the DRV5053EAQDBZRQ1?
The DRV5053EAQDBZRQ1 requires an output load impedance >10 kΩ and capacitive load <10 nF for stable operation. When interfacing with a microcontroller ADC, ensure the input impedance meets this minimum and that any external RC filter uses R ≥200 Ω and C ≤0.1 µF to avoid phase shift or instability. Exceeding these limits may cause output ringing or inaccurate readings.
