Product details
Overview
TLE4998C8XUMA2 from Infineon is a dual-die programmable linear Hall sensor IC with integrated 20-bit DSP, digital temperature/stress compensation, and SPC (Short PWM Code) output compliant with SAE J2716 SENT protocol. It delivers 16-bit resolution, ±50/±100/±200 mT configurable magnetic range, and operates from −40°C to +125°C. Used in automotive pedal position, throttle position, and steering torque sensing where high accuracy and AEC-Q100 compliance are mandatory.
For engineers reviewing the TLE4998C8XUMA2 datasheet, TLE4998C8XUMA2 pinout, TLE4998C8XUMA2 application, or TLE4998C8XUMA2 equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts for safety-critical position sensing designs requiring EEPROM-programmable gain, offset, bandwidth, and clamping.
Technical Context
The TLE4998C8XUMA2 integrates two independent Hall sensor dies in a single PG-TDSO-8 package, each with its own 20-bit DSP core, digital temperature compensation using second-order coefficients, and open-drain SPC output. It supports three SPC modes: synchronous transmission, dynamic range selection, and ID-selectable bus operation for up to four sensors on one line.
Its BiCMOS process enables reverse-polarity protection, 4.1–16 V extended supply range, and robust diagnostics including EEPROM error correction, overvoltage detection, and internal magnetic field/temperature reporting. The sensor uses chopped Hall elements and continuous-time A/D conversion to minimize magnetic offset drift over lifetime and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) based on SAE J2716 SENT - enables ECU-initiated transmissions and diagnostic nibble embedding. |
| Resolution | 16-bit overall resolution - supports precise linear/angular position quantization with <1 LSB total error over temperature. |
| Magnetic Range | Programmable ±50 mT / ±100 mT / ±200 mT - allows optimization for low-noise pedal sensing or wide-range throttle applications. |
| Operating Temp | −40°C to +125°C - qualified per AEC-Q100 Grade 0, enabling direct placement in engine bay or brake module environments. |
| Supply Voltage | 4.5–5.5 V nominal (4.1–16 V extended) - accommodates battery transients and simplifies power design in 12 V automotive systems. |
| Diagnostics | On-board EEPROM error correction, overvoltage detection, and internal temperature/magnetic field readback - reduces need for external monitoring circuitry. |
| Protection | Reverse-polarity, output short-circuit, and ±2 kV HBM ESD protection - ensures reliability in harsh assembly and field conditions. |
Pinout & Package
Package: PG-TDSO-8-1 (single-sensor variant), RoHS-compliant thermally enhanced SOIC-8 with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (TST) | Test pin | Factory test access; recommended connection to GND for stable operation and noise immunity. |
| 2 (VDD) | Supply voltage input | Primary power input for both Hall dies; accepts 4.5–5.5 V nominal with transient tolerance up to 16 V. |
| 3 (GND) | Ground reference | Common ground return for analog/digital blocks; critical for accurate magnetic offset stability. |
| 4 (OUT) | SPC output driver | Open-drain output requiring external pull-up; compatible with 3.3 V or 5 V receivers without level-shifting. |
| 5–8 | Not connected (NC) | Reserved for dual-die variant (TLE4998C8D); unused in TLE4998C8XUMA2 and must remain unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Two-point magnetic calibration | Enables field-to-digital transfer function setup without iterative loops - reduces production test time and calibration complexity. |
| Digital temperature compensation | Second-order coefficient storage in EEPROM - eliminates need for external thermistors or lookup tables in ECU firmware. |
| Reprogrammable EEPROM | Single-bit error correction and user-lock capability - supports post-soldering parameter tuning and secure final configuration. |
| SPC bus mode with ID selection | Supports up to 4 sensors on shared VDD/OUT lines - cuts wiring harness weight and connector count in multi-axis modules. |
| Internal diagnostics reporting | Real-time output of raw magnetic field and die temperature - enables predictive maintenance and fault isolation without additional sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis MLX90393 | Triaxis® 3D Hall with I²C/SPI interface; no SPC/SENT output; 20-bit resolution but fixed ±20 mT range. | Requires microcontroller-side protocol translation; suited for non-automotive industrial encoders or robotics. | Select when I²C/SPI host interface exists and SENT bus infrastructure is absent; not drop-in for ECU SPC receivers. |
| Allegro A1345 | 12-bit ratiometric analog output; no EEPROM programming; no temperature compensation; ±100 mT range only. | Lacks diagnostics, reprogramming, and digital compensation - limited to cost-sensitive non-safety applications. | Choose only for legacy analog signal chains where ECU ADC inputs exist and ASIL compliance is not required. |
Compared with MLX90393 and A1345, the TLE4998C8XUMA2 uniquely combines SENT-native output, EEPROM-based multi-parameter programmability, and AEC-Q100-certified diagnostics - making it the only option for new ASIL-B/C automotive position sensing designs requiring ECU-synchronized digital reporting.

FAQ
What is the difference between TLE4998C8XUMA2 and TLE4998C8D?
The TLE4998C8XUMA2 contains a single Hall sensor die in PG-TDSO-8-1 package, while TLE4998C8D integrates two independent dies in PG-TDSO-8-2. Pinouts differ: pins 5–8 are NC in XUMA2 but active (OUT/GND/VDD/TST) for the second die in C8D. Both share identical electrical specs and programming features.
Does TLE4998C8XUMA2 require an external pull-up resistor on the OUT pin?
Yes - the OUT pin is open-drain. A pull-up resistor to the receiver supply (e.g., 3.3 V or 5 V) is mandatory. Typical value is 2.2 kΩ; lower values improve rise time but increase current draw during low state. No internal pull-up is present.
Can magnetic range and sensitivity be reprogrammed after soldering?
Yes - all parameters (magnetic range, gain, offset, polarity, bandwidth, clamping, and temperature coefficients) are stored in EEPROM and can be reprogrammed in-system via the SPC interface until memory lock is enabled. Locking is irreversible and performed once final calibration is complete.
Is TLE4998C8XUMA2 qualified for ASIL-B or ASIL-C systems?
While not ASIL-certified itself, the TLE4998C8XUMA2 is AEC-Q100 Grade 0 qualified and includes PRO-SIL™ safety features (diagnostics, EEPROM ECC, fail-safe outputs). It is widely used in ASIL-B and ASIL-C subsystems when integrated with appropriate system-level safety mechanisms per ISO 26262.
