Product details
Overview
TLE49SRP8XUMA1 from Infineon Technologies is a stray field robust, differential Hall-based magnetic angle sensor delivering 360° absolute angular position measurement with ±1° intrinsic angle error over lifetime and temperature (−40 °C to +140 °C), PWM interface output, and ISO 26262 Safety Element out of Context qualification up to ASIL C(D) for automotive chassis height and steering angle sensing.
For engineers reviewing the TLE49SRP8XUMA1 datasheet, TLE49SRP8XUMA1 pinout, TLE49SRP8XUMA1 application, or TLE49SRP8XUMA1 equivalent, this page provides verified technical context on stray field immunity (±8 mT DC / ±1.25 mT AC per ISO 11452-8:2015), 14-bit angle resolution (0.022°/bit), EEPROM-configurable zero angle, and SICI single-wire programming - all validated under AEC-Q100 Grade 1.
Technical Context
The TLE49SRP8XUMA1 integrates spatially separated Hall cells and on-die signal conditioning to reject external magnetic interference while extracting precise angular position via CORDIC computation. Its functional block includes analog regulators, digital DSP, SENT/PWM/SPC interface logic, and EEPROM-backed calibration LUTs for systematic error correction.
It operates across 4.5–5.5 V supply at junction temperatures up to 140 °C, supports diagnostic functions including magnetic field out-of-range and voltage fault detection, and implements SPC Frameholder and SICI programming on the I/O pin - enabling in-system configuration without additional programming hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Accuracy | ±1° max intrinsic error over −40 °C to +140 °C and lifetime - enables direct use in ASIL-C safety-critical chassis position feedback without external compensation. |
| Angular Resolution | 14-bit over 360° (0.022°/bit) - supports high-fidelity closed-loop control in throttle and wiper systems requiring sub-degree repeatability. |
| Stray Field Immunity | ±8 mT DC / ±1.25 mT AC per ISO 11452-8:2015 Level IV - ensures reliable operation near motors, solenoids, or adjacent sensors in engine bay or suspension modules. |
| Interface Type | PWM output with programmable period (1–20 ms) and duty cycle encoding - compatible with standard microcontroller input capture peripherals without protocol stack overhead. |
| Supply Voltage Range | 4.5–5.5 V with 0.1–108 V/s slew rate tolerance - accommodates automotive battery transients and unregulated 5 V rails without external protection circuitry. |
| Diagnostic Coverage | Integrated magnetic field out-of-range, under-/overvoltage, and EEPROM CRC checks - satisfies ASIL-C diagnostic requirements as Safety Element out of Context. |
| EEPROM Capacity | Configurable zero angle offset, customer ID, and bus capability bits - enables factory calibration and multi-sensor differentiation without host MCU intervention. |
Pinout & Package
Package: PG-TDSO-8-1 (8-pin thin dual small outline, exposed thermal pad, RoHS/halogen-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I/O) | PWM output / SENT/SPC data / SICI programming | Single-pin bidirectional interface supporting output communication and in-system configuration - eliminates need for dedicated programming pins or external pull-ups in most designs. |
| 2 (CBuf) | Buffer capacitor connection | External 100 nF ceramic capacitor stabilizes internal analog regulator - critical for noise immunity and consistent angle accuracy under EMI stress. |
| 3 (GND) | Analog/digital ground reference | Common return path for Hall sensing, regulation, and interface circuits - must be low-impedance and thermally coupled to PCB copper pour for thermal stability. |
| 4 (VDD) | Primary power supply input | Accepts 4.5–5.5 V with reverse polarity and overvoltage protection up to −21 V / +26 V - simplifies front-end protection in 12 V automotive systems. |
| 5–8 (n.c.) | No connect | Unbonded pins; must remain unconnected and unpopulated on PCB - no routing or thermal vias permitted to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Hall architecture | Rejects common-mode stray fields via spatial separation of sensing elements - delivers stable 360° angle output even in magnetically noisy environments like EPS or transmission housings. |
| Look-up table (LUT) correction | On-chip EEPROM-stored LUT compensates for systematic errors induced by magnetic circuit asymmetry - reduces system-level calibration effort and improves end-of-line test yield. |
| SPC Frameholder mechanism | Enables deterministic timing alignment of multiple sensors on shared SPC bus - supports synchronized sampling in multi-axis chassis control applications. |
| SICI single-wire programming | Uses same I/O pin for both output communication and EEPROM configuration - eliminates need for separate programming header or debug interface during manufacturing or field updates. |
| AEC-Q100 Grade 1 qualification | Validated for 15,000 operating hours at 125 °C ambient and 54,000 ignition cycles - ensures reliability in under-hood and powertrain-mounted position sensing roles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A | 12-bit resolution, SPI-only interface, no integrated EEPROM or stray field immunity certification | Lacks AEC-Q100 Grade 1 qualification and ISO 11452-8 validation - limited to non-safety-critical industrial encoders | Select when cost-sensitive non-automotive designs require SPI simplicity and lower resolution suffices. |
| NXP MPXY8300 | Capacitive sensing principle, 10-bit output, no PWM interface, requires external ADC and signal conditioning | Not qualified to AEC-Q100; lacks diagnostic coverage and ASIL support - unsuitable for chassis or powertrain roles | Choose only for legacy capacitive-based systems where magnetic immunity is not required and resolution >10 bits is unnecessary. |
Compared with AMS AS5055A and NXP MPXY8300, the TLE49SRP8XUMA1 uniquely combines AEC-Q100 Grade 1, ISO 26262 SEooC up to ASIL C(D), ±1° accuracy over lifetime, and certified stray field immunity - making it the only drop-in solution for safety-critical automotive angle sensing where PWM interface and on-chip diagnostics are mandatory.

FAQ
What is the maximum allowable stray magnetic field for reliable operation?
The TLE49SRP8XUMA1 maintains full functionality under ±8 mT DC and ±1.25 mT AC stray fields per ISO 11452-8:2015 Level IV testing. This immunity is achieved through differential Hall cell geometry and on-die signal processing - no external shielding or compensation is required in typical automotive motor or solenoid environments.
Does the device support configuration after soldering to the PCB?
Yes. The TLE49SRP8XUMA1 supports in-system configuration via its SICI single-wire programming interface on Pin 1 (I/O), allowing EEPROM writes - including zero-angle offset, customer ID, and bus capability bits - without removing the device or adding dedicated programming hardware.
How does the PWM interface encode angle information?
Angle is encoded as duty cycle within a fixed-period PWM frame (programmable between 1–20 ms). A 0° reading corresponds to 0% duty cycle; 360° corresponds to 100%. The 14-bit resolution maps linearly across the range, yielding ~0.022° per LSB step - directly readable by standard microcontroller input-capture peripherals.
Is external capacitor CBUF mandatory, and what value is recommended?
Yes. A 100 nF ceramic capacitor must be placed between Pin 2 (CBuf) and GND to stabilize the internal analog regulator. This capacitor is essential for maintaining specified angle accuracy and noise immunity - omission results in increased jitter (>±0.5°) and susceptibility to supply ripple or EMI.
