Product details
Overview
TMAG5173D1QDBVRQ1 from Texas Instruments is a high-precision automotive-grade 3D linear Hall-effect sensor IC with integrated CORDIC angle engine, I²C interface, and ultra-low-power sleep mode (8 nA typical). It delivers ±1.1° X-Y angle error at room temperature, ±2.5% sensitivity error across X/Y/Z axes, and supports 20 kSPS single-axis conversion for steering column, shifter, and power seat position sensing.
For engineers reviewing the TMAG5173D1QDBVRQ1 datasheet, TMAG5173D1QDBVRQ1 pinout, TMAG5173D1QDBVRQ1 application, or TMAG5173D1QDBVRQ1 equivalent, this page provides verified functional safety (ASIL B hardware integrity), magnetic range configuration (±40/±80 mT), I²C CRC support, and thermal compensation details critical for automotive position-sensing system design.
Technical Context
The TMAG5173D1QDBVRQ1 integrates three orthogonal Hall elements with precision analog signal chains, a 16-bit ADC shared between magnetic and temperature channels, and an on-die CORDIC engine for real-time 360° angle calculation in X-Y, Y-Z, or Z-X planes. Its configurable averaging filter (up to 32× integration) reduces RMS magnetic noise to 15 µT (X/Y, CONV_AVG=101b, LP_LN=1b).
Functional safety architecture includes systematic capability up to ASIL D, hardware integrity compliant with ASIL B/SIL 2, and diagnostic coverage supporting ISO 26262 system-level development. The device operates across –40°C to +125°C with built-in temperature sensor (±0.5°C typical error) and programmable magnetic temperature compensation (0–0.2%/°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - compatible with automotive 3.3 V rails and tolerant to 5.5 V on I²C/INT pins. |
| Operating Temperature | –40°C to +125°C - AEC-Q100 Grade 1 qualified for under-hood and cabin applications. |
| X-Y Angle Error | ±1.1° max at 25°C - enables high-fidelity steering wheel or joystick angular position detection. |
| Sensitivity Error | ±2.5% max across X/Y/Z axes - ensures consistent field-to-digital linearity without per-axis calibration. |
| Sleep Current | 8 nA typical - extends battery life in always-on vehicle modules like door latches or e-bike controllers. |
| I²C Speed | Up to 1 MHz - supports fast host polling in time-critical actuator feedback loops. |

Pinout & Package
TMAG5173D1QDBVRQ1 is housed in a 6-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, optimized for space-constrained automotive PCBs. Pin 3 (GND_TEST) must be connected to ground in final application.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SCL) | I²C clock input/output | Accepts up to 1 MHz clock; supports interrupt signaling when configured in SCL-interrupt mode. |
| 2 (GND) | Power ground reference | Main return path for analog and digital circuitry; decoupling capacitor must be placed adjacent. |
| 3 (GND_TEST) | TI factory test pin | Not functional in application; requires connection to GND to ensure proper operation and ESD robustness. |
| 4 (VCC) | Primary supply input | 2.3–3.6 V nominal; under-voltage lockout triggers at 1.9–2.2 V to prevent erratic behavior during brownout. |
| 5 (INT) | Configurable interrupt output/input | Signals magnetic/temperature threshold crossings; supports fixed-width or latched modes via INT_STATE register. |
| 6 (SDA) | I²C bidirectional data line | Includes integrated CRC for error detection; 5.5 V tolerant to simplify level-shifting in mixed-voltage systems. |
Key Features
| Feature | Design Value |

| Configurable magnetic range selection | Per-axis ±40 mT / ±80 mT options (D1 variant) - matches magnet strength and air gap without hardware change. |
| Programmable temperature compensation | Four TEMPCO settings (0–0.2%/°C) - corrects sensitivity drift across –40°C to +125°C for stable angle accuracy. |
| Dual-mode interrupt generation | INT or SCL pin can trigger on magnetic/temperature threshold crossing - enables flexible host wake-up strategies. |
| Ultra-low-power sleep mode | 8 nA typical current with register retention - maintains calibrated state while minimizing quiescent drain in battery-powered modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D Hall-effect sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMAG5170D1QDBVRQ1 | No integrated CORDIC engine; outputs only raw X/Y/Z data - requires external MCU for angle calculation. | Lacks on-chip 360° angle computation; suitable where host processor has spare cycles and deterministic latency is less critical. | Select TMAG5170D1QDBVRQ1 if system-level angle processing is already centralized and BOM cost reduction is prioritized over latency and code footprint. |
| MLX90393ELW-ABA-000-RE | Tri-axis Hall sensor with SPI interface; ±0.5° typical angle error but no ASIL B hardware integrity certification. | Used in industrial joysticks and non-safety-critical automotive accessories; lacks ISO 26262 documentation support. | Choose MLX90393ELW-ABA-000-RE for cost-sensitive non-automotive designs where functional safety compliance is not required. |
Compared with TMAG5173D1QDBVRQ1, TMAG5170D1QDBVRQ1 reduces computational load on the host but increases system latency and firmware complexity, while MLX90393ELW-ABA-000-RE offers lower angle error in benign environments but omits automotive safety certification and I²C CRC protection.

FAQ
What magnetic field ranges does TMAG5173D1QDBVRQ1 support?
TMAG5173D1QDBVRQ1 supports two factory-programmed magnetic ranges: ±40 mT and ±80 mT on all three axes (X, Y, Z), selected independently via x_y_RANGE and z_RANGE configuration bits. This D1 variant is optimized for moderate-strength magnets used in steering columns and shifter mechanisms, with sensitivity values of 844 LSB/mT (±40 mT) and 425 LSB/mT (±80 mT).
How does TMAG5173D1QDBVRQ1 achieve ASIL B hardware integrity?
TMAG5173D1QDBVRQ1 achieves ASIL B hardware integrity through redundant internal diagnostics, voltage/temperature monitoring, CRC-protected I²C communication, and systematic design processes aligned with ISO 26262. Its failure-in-time (FIT) rate and diagnostic coverage metrics are documented in TI's functional safety FIT report for TMAG5173-Q1, enabling integration into ASIL B–compliant systems like power seats and door modules.
Can TMAG5173D1QDBVRQ1 operate with a 5 V microcontroller I²C bus?
Yes - TMAG5173D1QDBVRQ1's SDA and INT pins are 5.5 V tolerant, and its I²C interface operates with VCC = 2.3–3.6 V while accepting 0–5.5 V logic levels on SDA/SCL. No external level shifter is needed when interfacing with 5 V MCUs, simplifying design and reducing component count in mixed-voltage automotive ECUs.
What is the role of the TEST pin (Pin 3) on TMAG5173D1QDBVRQ1?
Pin 3 is labeled GND (TEST) and is a TI factory test node. It must be connected to system ground in all production applications. Leaving it floating may compromise ESD performance and cause undefined behavior. This pin is not user-configurable and carries no active signal in normal operation.
Does TMAG5173D1QDBVRQ1 support both latched and pulse-mode interrupts?
Yes - TMAG5173D1QDBVRQ1 supports latched and fixed-width interrupt modes on the INT pin, controlled by the INT_STATE register bit. In latched mode (INT_STATE = 0), the INT pin remains asserted until cleared by a valid I²C address transaction. In fixed-width mode (INT_STATE = 1), it pulses for 10 µs upon magnetic or temperature threshold crossing, enabling edge-triggered wake-up in ultra-low-power systems.
