Product details
Overview
TLE4990HAXA1 from Infineon Technologies is a programmable linear-output Hall-effect sensor IC designed for high-accuracy position and current sensing in automotive powertrain and chassis systems. It delivers ratiometric analog output (0–5 V at 5 V supply), supports magnetic field ranges up to ±200 mT, features factory-calibrated 20 mV/mT sensitivity, and operates across –40 °C to +150 °C in a PG-SSO-4-1 package.
For engineers reviewing the TLE4990HAXA1 datasheet, TLE4990HAXA1 pinout, TLE4990HAXA1 application, or TLE4990HAXA1 equivalent, key selection criteria include its fused factory calibration, rail-to-rail push-pull output, on-board wire-break diagnostics, programmable offset/gain (in non-fused variants), and AEC-Q100 qualification for under-hood use.
Technical Context
The TLE4990HAXA1 implements a chopped Hall probe with dynamic offset cancellation to suppress mechanical stress and thermal drift. Its signal chain includes temperature-compensated gain modulation (±350 ppm/°C), 10-bit ODAC for zero-field voltage tuning, and PRE/GDAC-based coarse-fine sensitivity programming.
It uses BiCMOS technology with reverse-polarity and overvoltage protection on all pins. The -E6782 variant (HAXA1) has permanently fused parameters: fixed 20 mV/mT sensitivity, disabled clamping, locked memory, and calibrated offset at 50% VDD - eliminating field programming requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V DC; enables direct connection to automotive 5 V rails without regulation. |
| Output Type | Ratiometric rail-to-rail push-pull analog (0–VDD); eliminates need for external reference in ADC interfacing. |
| Magnetic Sensitivity | 20 mV/mT at 5 V; factory-fused, enabling consistent current/position scaling across production lots. |
| Operating Temperature | –40 °C to +150 °C; qualified for engine bay and transmission control unit mounting locations. |
| Zero-Field Output | 50% VDD (2.5 V at 5 V); fused offset ensures stable null point without calibration in end equipment. |
| Output Short-Circuit Protection | Integrated; sustains indefinite short to GND or VDD without latch-up or damage. |
| Diagnostic Function | On-board wire-break detection; forces output to ≤6% or ≥94% VDD on open-circuit fault. |
Pinout & Package
PG-SSO-4-1: 4-pin surface-mount package, 1 mm profile height, 5.34 mm width, 3.0 mm length, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TST) | Test pin | Must be grounded externally; used internally for factory test and calibration, not user-accessible. |
| 2 (OUT) | Analog output / programming interface | Push-pull ratiometric voltage output; also serves as 1-wire programming port in unfused variants (disabled in HAXA1). |
| 3 (GND) | Ground reference | Primary return path for supply and output current; connects to substrate for ESD robustness. |
| 4 (VDD) | Supply input | Accepts 4.5–5.5 V with integrated reverse-polarity and overvoltage protection. |
Key Features
| Feature | Design Value |
|---|---|
| Fused factory calibration | Eliminates end-of-line programming: sensitivity (20 mV/mT), offset (50% VDD), and tempco (+350 ppm/°C) are permanently set. |
| Rail-to-rail push-pull output | Drives ADC inputs directly without level-shifting or external pull-ups; supports 10+ kΩ load impedance. |
| Wire-break diagnostics | Self-detects open-circuit faults on OUT line by forcing output beyond 6% or 94% VDD thresholds. |
| High-temp operation | Guaranteed functionality at 150 °C ambient enables placement near engines, inverters, and gearboxes. |
| Reverse polarity protection | Withstands –18 V on VDD or GND pins without damage - critical for battery-connected automotive modules. |
Applications
| Pedal Position Sensing | Throttle Valve Position |
|---|---|
Use Scenario: Detect accelerator pedal angle in gasoline/diesel engine management systems with mechanical redundancy. IC Role / Device Role / Timing Role: Linear Hall sensor providing analog voltage proportional to pedal rotation (0–100% stroke → 0–5 V). Use Value: Replaces wear-prone potentiometers; maintains ±1.5% full-scale accuracy over 10M cycles and –40–150 °C. | Use Scenario: Monitor throttle plate angular position in electronic throttle control (ETC) modules. IC Role / Device Role / Timing Role: Primary position transducer feeding closed-loop air-fuel ratio control via ECU ADC. Use Value: Delivers <1.2% linearity error and <0.5% thermal drift over lifetime - meeting ASIL-B functional safety requirements. |
| Steering Angle Sensing | Battery Current Monitoring |
Use Scenario: Measure absolute steering wheel angle for EPS assist torque calculation and lane-keeping systems. IC Role / Device Role / Timing Role: Dual-sensor configuration (redundant) reporting analog angle signals to steering ECU. Use Value: Enables <±0.3° angular accuracy at 150 °C with built-in diagnostics for fail-safe torque limiting. | Use Scenario: Sense high-side battery current in 12 V starter-battery monitoring for start-stop and state-of-charge estimation. IC Role / Device Role / Timing Role: Closed-loop current sensor using external conductor and magnetic concentrator. Use Value: Achieves ±2% full-scale accuracy from –40–125 °C without shunt resistor heating or isolation components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis MLX90242 | Programmable gain/offset via I²C; 16-bit resolution; no fused calibration; requires external EEPROM. | Used where field recalibration or multi-range flexibility is needed (e.g., adaptive suspension). | Select when programmability outweighs production calibration simplicity. |
| Allegro A1324 | Fixed 5 mV/G sensitivity; no diagnostics; wider supply range (3–24 V); uncalibrated offset drift. | Suitable for cost-sensitive industrial position feedback, not automotive safety-critical systems. | Select only for non-AEC-Q100 applications requiring wide-VDD operation and lower cost. |
Compared with MLX90242 and A1324, the TLE4990HAXA1 provides guaranteed factory calibration, integrated diagnostics, and AEC-Q100 qualification - making it optimal for production automotive systems where validation effort and long-term stability are prioritized over field reconfiguration.

FAQ
Is TLE4990HAXA1 pin-compatible with other TLE4990 variants?
Yes - all TLE4990 variants (including HAXA1, HA1, and unfused versions) share identical PG-SSO-4-1 packaging and pinout (TST/OUT/GND/VDD). However, HAXA1 has permanently fused parameters and disabled programming capability, while others support field configuration via the OUT pin.
Does TLE4990HAXA1 require external components for basic operation?
No - it operates with only VDD and GND connections. The TST pin must be tied to GND. No external capacitors, resistors, or magnetics are required for standard position sensing; an external magnet and mechanical coupling are the only system-level dependencies.
What is the meaning of "HAXA1" in the part number?
HAXA1 denotes the Infineon-specific ordering code for the TLE4990-E6782 variant: "HA" indicates automotive grade, "XA" specifies the factory-fused 20 mV/mT sensitivity and 50% VDD offset, and "1" designates tape-and-reel packaging per JEDEC standard.
Can TLE4990HAXA1 be used in safety-critical ASIL-B systems?
Yes - it is AEC-Q100 qualified (Grade 0), includes on-board diagnostics (wire-break detection), and features fused calibration ensuring consistent performance. System-level ASIL-B compliance requires proper integration into fault-tolerant architectures per ISO 26262, but the device itself meets foundational hardware requirements.
