Product details
Overview
DRV5053PAQDBZRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive analog bipolar Hall effect sensor in a 3-pin SOT-23 (DBZ) package, delivering –23 mV/mT sensitivity, 0.2–1.8 V ratiometric output, and operation across –40°C to +125°C ambient. It provides linear magnetic field sensing for position and motion detection in engine control, damper systems, and flow meters.
For engineers reviewing the DRV5053PAQDBZRQ1 datasheet, DRV5053PAQDBZRQ1 pinout, DRV5053PAQDBZRQ1 application, or DRV5053PAQDBZRQ1 equivalent, key selection criteria include its ±23 mV/mT sensitivity, 2.7–38 V supply range, reverse supply protection to –22 V, 35 µs power-on time, and integrated output short-circuit and load-dump resilience.
Technical Context
The DRV5053PAQDBZRQ1 uses chopper-stabilized Hall technology to achieve ±10% sensitivity stability over temperature and reject offset drift. Its analog output stage delivers 300 µA source / 2.3 mA sink capability with quiescent output fixed at 1 V (±102 mV) at zero magnetic field.
It operates across a wide 2.7–38 V DC supply, tolerates transient 40 V load dumps, and survives continuous –22 V reverse polarity. The device enters inactive state only when VCC falls below 2.7 V or exceeds 38 V - no external regulator or protection circuitry is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sensitivity | –23 mV/mT (typical at VCC = 3.3 V); enables high-resolution detection of small magnetic field changes in proximity or rotation sensing |
| Output Range | 0.2–1.8 V; full-scale analog swing centered at 1 V (B = 0 mT), compatible with 2.0 V ADC reference rails |
| Supply Voltage | 2.7–38 V; supports direct connection to automotive battery without external regulation or voltage translation |
| Operating Temp | –40°C to +125°C (Grade 1); qualified for under-hood and transmission-mounted applications per AEC-Q100 |
| Power-On Time | 35 µs (typical); ensures rapid system readiness after ignition or wake-up events |
| Input Noise | 0.49 mTpp (typical); low noise floor supports stable analog measurements in vibration-prone environments |
| Bandwidth | 20 kHz; sufficient for real-time monitoring of fast mechanical motion such as valve timing or gear tooth detection |
Pinout & Package
DRV5053PAQDBZRQ1 is housed in a surface-mount 3-pin SOT-23 (DBZ) package measuring 2.92 mm × 2.37 mm × 1.30 mm, optimized for compact PCB layouts and automated assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV5055VAQDBZRQ1 | +90 mV/mT sensitivity, higher noise (44 mVpp), same DBZ package and AEC-Q100 Grade 1 rating | Better suited for weak-field detection (e.g., large air gaps), but less resolution in moderate-field ranges | Select DRV5055VAQDBZRQ1 only when magnetic field strength is <10 mT and higher gain is required |
| ALLEGRO A1302LLHLT-T | –1.3 mV/G (–13 mV/mT) sensitivity, wider operating temp (–40°C to +150°C), TO-92 package only | Lacks reverse supply protection (–18 V max), no load dump tolerance, requires external bypass and filtering | Choose A1302LLHLT-T only for non-critical industrial applications where cost outweighs automotive robustness |
Compared with DRV5053PAQDBZRQ1, DRV5055VAQDBZRQ1 offers higher gain but reduced linearity and increased noise, while A1302LLHLT-T lacks integrated protection and automotive qualification rigor - making DRV5053PAQDBZRQ1 the optimal choice for safety-critical, high-reliability automotive sensing.

FAQ
What is the sensitivity and polarity behavior of the DRV5053PAQDBZRQ1?
The DRV5053PAQDBZRQ1 has a nominal sensitivity of –23 mV/mT. A south pole near the marked side of the package produces a negative magnetic field, causing the output voltage to decrease below 1 V; a north pole increases it above 1 V. This polarity response is consistent across its full operating temperature range and enables bidirectional position sensing without external signal inversion.
Does the DRV5053PAQDBZRQ1 require external filtering for stable operation?
No external filtering is required for basic operation of the DRV5053PAQDBZRQ1. Its internal architecture supports stable output with only a 0.01 µF ceramic bypass capacitor on VCC. However, if system-level noise exceeds requirements, an external RC filter (e.g., 10 kΩ + 1500 pF) can reduce bandwidth to 5 kHz and lower output noise to ~9.7 mVpp - as validated in TI's filtered typical application schematic.
How does the DRV5053PAQDBZRQ1 handle reverse battery conditions?
The DRV5053PAQDBZRQ1 withstands continuous reverse supply voltages down to –22 V without damage or latch-up. During reverse bias (–22 V < VCC < 0 V), the device remains inactive but fully protected. Recovery occurs automatically once VCC returns to ≥2.7 V. This eliminates need for external reverse-polarity diodes in automotive harness designs.
What is the maximum capacitive load allowed on the DRV5053PAQDBZRQ1 OUT pin?
The DRV5053PAQDBZRQ1 OUT pin supports a maximum capacitive load of 10 nF to ensure amplifier stability. Exceeding this value may cause oscillation or slow settling. If additional filtering is needed, TI recommends using an external series resistor ≥200 Ω with capacitor ≤0.1 µF - a configuration verified to maintain stability while reducing high-frequency noise in the DRV5053PAQDBZRQ1 output path.
Can the DRV5053PAQDBZRQ1 operate directly from a 24 V truck battery system?
Yes, the DRV5053PAQDBZRQ1 operates across 2.7–38 V, making it fully compatible with 24 V commercial vehicle battery systems. It tolerates 40 V load dump transients without external clamping and maintains specified performance from –40°C to +125°C - meeting ISO 16750-2 pulse 5b requirements for heavy-duty automotive applications.
