Product details
Overview
TLE5012BE3005XUMA1 from Infineon Technologies is a GMR-based 360° absolute angle sensor with integrated sine/cosine signal processing, 15-bit angle resolution (0.01°), bi-directional SSC interface up to 8 Mbit/s, and automotive-grade operation from −40°C to +150°C junction temperature. It delivers calibrated angular position data for electric power steering (EPS) motor commutation and supports Hall Switch Mode (HSM) output configuration per its E3005 derivative marking.
For engineers reviewing the TLE5012BE3005XUMA1 datasheet, TLE5012BE3005XUMA1 pinout, TLE5012BE3005XUMA1 application in EPS or steering angle sensing, or TLE5012BE3005XUMA1 equivalent for SIL-compliant angular position feedback, this page provides verified functional context, interface behavior, safety diagnostics, and package-specific design guidance.
Technical Context
The TLE5012BE3005XUMA1 implements dual sigma-delta ADCs to digitize analog GMR bridge outputs, followed by CORDIC-based arctangent computation to derive absolute angle. Its digital signal processing unit includes a CCU (Cycle Control Unit) for timing synchronization and RAM for calibration parameter storage loaded from laser fuses at startup.
It features a PLL clock generator configurable to accept external clock via IFC pin - but only when operating in PWM or SPC mode - and integrates PRO-SIL™ safety mechanisms including BIST for ISM, CORDIC, CCU, and ADCs, plus CRC-8 for SSC and CRC-4 nibble for SPC data integrity verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Resolution | 15-bit absolute angle output (0.01° step size), enabling high-precision rotor position tracking in BLDC motor control. |
| Angle Accuracy | Max. ±1.0° total error over lifetime and −40°C to +150°C with auto-calibration enabled, meeting ASIL-B requirements. |
| Interface Modes | Pre-configured Hall Switch Mode (HSM) output; also supports SSC, PWM, IIF, and SPC - all configurable via registers or factory fuse settings. |
| Supply Range | VDD = 4.5 V to 5.5 V; internal regulators (VRG, VRA, VRD) provide stable biasing for GMR, analog, and digital blocks independently. |
| ESD Robustness | ≥4 kV HBM rating ensures resilience against handling and system-level electrostatic discharge in automotive assembly environments. |
| Safety Certification | AEC-Q100 qualified; supports Safety Integrity Level (SIL) via built-in diagnostics including over/undervoltage detection and CRC-protected communication. |
| Technology Node | 0.25 µm CMOS process enables integration of GMR elements, SD-ADCs, digital logic, and safety monitors on single die. |
Pinout & Package
Package: PG-DSO-8 (8-pin exposed pad SOIC variant, RoHS-compliant, halogen-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary supply input | 4.5–5.5 V main power rail; feeds internal voltage regulators (VRG/VRA/VRD) for analog and digital domains. |
| GND | Ground reference | Digital and analog ground common point; requires low-inductance connection to minimize noise coupling into GMR sensing path. |
| CSQ | SSC chip select / HSM output enable | In HSM mode (E3005), functions as open-drain or push-pull Hall switch output; in SSC mode, acts as slave select. |
| SCK | SSC clock input | Accepts up to 8 MHz clock for synchronous serial communication; also used for external PLL clock injection in PWM/SPC modes. |
| DATA | SSC bidirectional data line | Half-duplex data channel for register read/write and angle data transfer; supports CRC-8 for error detection. |
| IFC | Interface configuration / external clock input | Configures interface mode at power-up; accepts external clock for PLL synchronization only in PWM or SPC configurations. |
| IFA / IFB | Differential incremental outputs | Quadrature A/B signals for legacy encoder replacement; available in IIF mode, not active in default E3005 HSM configuration. |
Key Features
| Feature | Design Value |
|---|---|
| GMR Sensing Architecture | Monolithic integrated iGMR elements eliminate external magnet alignment sensitivity and reduce mechanical tolerance stack-up in EPS assemblies. |
| Auto-Calibration Algorithm | Runtime compensation for thermal drift and aging effects, reducing need for end-of-line recalibration in production test flow. |
| Multi-Interface Flexibility | HSM output pre-configured for direct replacement of Hall-effect switches while retaining upgrade path to SSC/PWM for higher-resolution feedback. |
| PRO-SIL™ Diagnostic Suite | Built-in self-test (BIST) at startup verifies critical signal chains (ISM, CORDIC, CCU, ADCs); CRC and supply monitoring support ASIL-B compliance evidence. |
| Bus-Mode Operation | Multiple TLE5012B sensors can share one SSC or SPC bus line using unique device addressing, simplifying wiring in multi-axis steering systems. |
Applications
| Electric Power Steering (EPS) | Steering Column Angle Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMR-based angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5055A-DSOT | 14-bit resolution (0.022°), SPI-only interface, no HSM mode; lacks integrated autocalibration and PRO-SIL™ diagnostics. | Targeted at industrial encoders; not AEC-Q100 qualified or rated for >125°C ambient. | Choose for cost-sensitive non-automotive designs where 15-bit resolution and ASIL-B support are unnecessary. |
| TLE5012B E1000 XUMA1 | Same die, pre-configured for Incremental Interface (IIF) instead of HSM; identical accuracy, package, and safety features. | Used where quadrature A/B signals required for legacy MCU timer input capture rather than digital switch emulation. | Select when replacing optical or magnetic incremental encoders and retaining existing firmware interrupt handlers. |
Compared with AS5055A-DSOT, TLE5012BE3005XUMA1 offers superior automotive qualification, higher resolution, and embedded safety diagnostics; versus TLE5012B E1000, it trades IIF output for HSM functionality - both share identical sensing core and calibration infrastructure.

FAQ
What interface modes does TLE5012BE3005XUMA1 support out-of-the-box?
This part is factory pre-configured as an E3005 derivative, meaning Hall Switch Mode (HSM) is its default active interface. It retains full capability to reconfigure via SSC to PWM, SPC, IIF, or SSC - but HSM is enabled at power-on without register writes. The CSQ pin operates as a programmable open-drain or push-pull switch output with adjustable hysteresis and threshold.
How does the autocalibration function improve long-term accuracy?
The autocalibration algorithm continuously monitors sine/cosine signal offsets and gains during normal operation, updating correction parameters stored in volatile registers. When activated, it reduces total angle error to ≤±1.0° over −40°C to +150°C and 15-year lifetime - compensating for thermal drift, mechanical stress relaxation, and magnetic aging without external intervention.
Can multiple TLE5012BE3005XUMA1 sensors share one SSC bus line?
Yes - bus-mode operation is supported via unique device addressing through the SSC interface. Each sensor must be assigned a distinct address during initialization; the shared SCK and DATA lines allow daisy-chained or parallel topologies. This is commonly used in multi-axis steering systems where compact cabling and synchronized sampling are required.
Is external clock injection supported in HSM mode?
No - external clock injection via the IFC pin is only available when the device is configured for PWM or SPC interface operation. In default HSM mode, the internal oscillator drives the PLL. To use external clock synchronization, the device must first be reconfigured via SSC to PWM or SPC mode, then the IFC pin becomes active as clock input.
