Product details
Overview
TMAG5253BA2IQDMRR from Texas Instruments is a bipolar linear Hall effect sensor with dedicated enable pin, ±40 mT magnetic sensing range, 30 mV/mT sensitivity (typ @ 3.3 V), <25 µs power-on time, and ultra-low 2 mA active current at 1.8 V - deployed in mobile robot motor control and cordless power tools for precise position feedback under tight power budgets.
For engineers reviewing the TMAG5253BA2IQDMRR datasheet, TMAG5253BA2IQDMRR pinout, TMAG5253BA2IQDMRR application, or TMAG5253BA2IQDMRR equivalent, key selection criteria include shutdown current (<20 nA), ratiometric analog output architecture, X2SON-4 package footprint (1.40 mm × 1.10 mm), temperature-compensated sensitivity, and bipolar magnetic polarity support for differential field detection.
Technical Context
The TMAG5253BA2IQDMRR implements a ratiometric analog output stage where quiescent voltage (VQ ≈ VCC/2) and sensitivity scale linearly with supply voltage - enabling error cancellation when paired with an ADC using the same VCC reference. Its internal temperature compensation counteracts neodymium magnet drift across –40°C to 125°C.
It features a dedicated EN input with hysteresis (VIL = 0.35×VCC, VIH = 0.65×VCC) to control fast transition between active mode (2 mA, <25 µs tON) and shutdown mode (<20 nA, high-Z output). Magnetic field is sensed perpendicular to the top surface of the X2SON package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V – 3.6 V - supports single-cell Li-ion and dual-cell alkaline systems without LDO. |
| Active Supply Current | 2 mA @ 1.8 V - enables >100-hour battery life in 100 Hz duty-cycled applications. |
| Shutdown Current | <20 nA @ 1.8 V - preserves energy during extended sleep states in portable devices. |
| Magnetic Sensing Range | ±40 mT - optimized for robust detection of standard NdFeB magnets at 1–3 mm air gaps. |
| Sensitivity | 30 mV/mT (typ @ 3.3 V) - delivers ~2.4 V full-scale swing across ±40 mT range, compatible with 12-bit ADCs. |
| Power-On Time | <25 µs (bipolar) - meets real-time response requirements in motor commutation and safety-critical proximity sensing. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive accessories and industrial motor drives. |
Pinout & Package
X2SON-4 (DMR) package: 1.40 mm × 1.10 mm footprint, 0.4 mm pitch, thermal pad on bottom for PCB heat dissipation. No external passive components required beyond 0.1 µF VCC-to-GND ceramic capacitor.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Power supply input | Accepts 1.65–3.6 V; requires local 0.1 µF decoupling to GND for noise immunity. |
| GND (Pin 2) | Ground reference | Low-impedance return path; must be connected to thermal pad for optimal thermal performance. |
| EN (Pin 3) | Enable control input | Active-high logic; 0.35×VCC/0.65×VCC thresholds enable robust noise margin in noisy environments. |
| OUT (Pin 4) | Analog output | Ratiometric voltage output (0.2 V to VCC–0.2 V); high-impedance (>9 MΩ) in shutdown mode allows multi-sensor sharing of ADC input. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated enable pin with hysteresis | Eliminates false wake-up from EMI; supports deterministic low-power sequencing in microcontroller-based systems. |
| Ratiometric analog output | Removes VCC tolerance error when ADC uses same supply as reference - improves absolute accuracy without calibration. |
| Magnet temperature compensation | 0.12 %/°C STC matches NdFeB flux decay, maintaining consistent sensitivity across –40°C to 125°C ambient. |
| High-impedance shutdown output | Enables multiple TMAG5253BA2IQDMRR sensors on one ADC channel - reduces BOM count and PCB area in multi-axis systems. |
| Ultra-small X2SON-4 footprint | 1.54 mm² total area - fits within mechanical constraints of gaming controllers and vacuum robot wheel assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall effect sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMAG5170AHQDGKR | 3D Hall sensor with I²C interface; higher cost; ±50 mT range; 16-bit digital output. | Requires MCU firmware support for register access; suited for multi-axis tilt/orientation sensing. | Select when vector field measurement or digital interface is required - not a drop-in replacement. |
| ALLEGRO A1324LLHLT-T | Unipolar linear Hall IC; no enable pin; 5 V supply only; ±500 G (±50 mT) range; 5 V ratiometric output. | Lacks shutdown mode and low-voltage operation; incompatible with 1.8 V systems. | Choose only for legacy 5 V designs where ultra-low power is not critical. |
Compared with TMAG5253BA2IQDMRR, TMAG5170AHQDGKR adds 3D sensing and digital output at higher cost and complexity, while A1324LLHLT-T lacks enable control and fails to meet modern battery-powered voltage requirements - making TMAG5253BA2IQDMRR the optimal choice for space-constrained, low-voltage, duty-cycled proximity sensing.

FAQ
What is the magnetic polarity type supported by the TMAG5253BA2IQDMRR?
The TMAG5253BA2IQDMRR is a bipolar linear Hall effect sensor: it produces distinct positive and negative output voltages in response to north and south magnetic poles, centered around VCC/2 at zero field. This enables differential position tracking and direction detection - unlike unipolar variants such as TMAG5253UA2IQDMRR.
Does the TMAG5253BA2IQDMRR require external passive components for basic operation?
Yes - a 0.1 µF ceramic capacitor must be placed between VCC and GND, close to the TMAG5253BA2IQDMRR pins, to ensure stable operation and reduce supply noise coupling. No pull-up/pull-down resistors or output filtering are required for standard use cases per the datasheet recommendations.
How does the ratiometric architecture of the TMAG5253BA2IQDMRR improve system accuracy?
The TMAG5253BA2IQDMRR's ratiometric architecture ensures both quiescent voltage and sensitivity scale linearly with VCC. When used with an ADC that references the same VCC, supply voltage tolerance errors cancel - delivering consistent digital readings independent of battery sag or regulator variation, without factory calibration.
What is the maximum recommended load capacitance on the OUT pin of the TMAG5253BA2IQDMRR?
The TMAG5253BA2IQDMRR specifies a maximum load capacitance of 1 nF on the OUT pin under recommended operating conditions. Exceeding this value may degrade bandwidth (15 kHz –3 dB point) and increase settling time, potentially affecting dynamic response in high-speed position sensing applications.
Can the TMAG5253BA2IQDMRR operate reliably at 125°C junction temperature?
Yes - the TMAG5253BA2IQDMRR is fully specified from –40°C to 125°C ambient temperature. Thermal data shows RθJA = 157.1°C/W for the X2SON-4 package; with proper PCB copper area under the thermal pad, sustained 125°C operation is achievable in motor control and power tool applications.
