Product details
Overview
TLE5012BE5000FUMA1 from Infineon Technologies is a GMR-based 360° absolute angle sensor with integrated sine/cosine signal processing, 15-bit angle resolution (0.01°), ±1.0° total angle error over temperature and lifetime (with auto-calibration), and dual SD-ADCs for high-precision magnetic field measurement - deployed in electric power steering (EPS) motor commutation.
For engineers reviewing the TLE5012BE5000FUMA1 datasheet, TLE5012BE5000FUMA1 pinout, TLE5012BE5000FUMA1 application, or TLE5012BE5000FUMA1 equivalent, key selection criteria include SSC/PWM interface flexibility, SIL-compliant diagnostics, automotive-grade junction temperature range (−40°C to +150°C), and pre-configured E5000 PWM output mode.
Technical Context
The TLE5012BE5000FUMA1 implements a monolithic GMR sensing architecture with two independent sigma-delta ADCs digitizing raw sine and cosine analog outputs from integrated iGMR elements. Its digital signal path includes CORDIC-based angle computation, revolution counting, and angular speed derivation.
It features a configurable PLL that accepts either internal oscillator or external clock via IFC pin (in PWM/SPC modes), supports concurrent SSC configuration and PWM data output, and embeds BIST routines for ISM, CORDIC, CCU, and ADCs at startup - all operating under AEC-Q100 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Resolution | 15-bit absolute angle output = 0.01° quantization step for precise rotor position feedback. |
| Angle Accuracy | Max. ±1.0° total error over −40°C to +150°C junction temp and lifetime when auto-calibration enabled. |
| Interface Mode | Pre-configured PWM output (E5000 derivative); bi-directional SSC available for configuration and diagnostics. |
| Supply Range | VDD = 4.5 V to 5.5 V - compatible with standard automotive 5 V rail; internal regulators (VRG/VRA/VRD) ensure stable analog/digital domains. |
| Operating Temp | −40°C to +150°C junction temperature - validated for EPS, transmission, and engine bay placement. |
| ESD Robustness | >4 kV HBM - meets automotive system-level ESD immunity requirements without external protection. |
| Safety Compliance | Supports ASIL-B per ISO 26262 via CRC-checked SSC/SPC, built-in self-test, and voltage monitoring diagnostics. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, halogen-free, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power Supply Input | 4.5–5.5 V main supply; powers internal regulators (VRG/VRA/VRD) for GMR, analog, and digital blocks. |
| GND | Ground Reference | Analog/digital common ground; critical for low-noise GMR signal integrity and ADC reference stability. |
| IFC | External Clock Input | Accepts external clock for PLL synchronization in PWM/SPC modes; enables deterministic timing across multi-sensor systems. |
| CSQ | SSC Chip Select / PWM Output | In E5000 config: PWM output pin (programmable push-pull/open-drain); in SSC mode: active-low chip select. |
| SCK | SSC Clock | Bi-directional SPI-compatible clock input; used only during SSC communication, not during PWM operation. |
| DATA | SSC Data I/O | Half-duplex bidirectional data line for register read/write and diagnostic reporting via SSC interface. |
| IFA / IFB | Differential Incremental Outputs | Quadrature A/B signals (optional IIF mode); unused in E5000 PWM configuration but electrically present. |
Key Features
| Feature | Design Value |
|---|---|
| Pre-configured PWM Interface (E5000) | Single-wire, duty-cycle-modulated angle output (0%–100% = 0°–360°) with no external controller required for basic readout. |
| Auto-Calibration Algorithm | On-chip runtime compensation for GMR offset/gain drift over temperature and aging - reduces need for external calibration infrastructure. |
| Dual Independent SD-ADCs | Simultaneous 16-bit sine/cosine digitization enables robust arctangent computation and rejection of common-mode noise. |
| Multi-Interface Coexistence | SSC remains fully functional for configuration/diagnostics while PWM delivers real-time angle data - no interface arbitration needed. |
| Integrated Safety Diagnostics | Includes CRC-8 (SSC), CRC-4 nibble (SPC), BIST on critical IP blocks, and VDD/GND off-detection - supports ASIL-B decomposition. |
Applications
| Electric Power Steering (EPS) | Throttle Valve Position Sensing |
|---|---|
|
Use Scenario: Real-time rotor angle feedback for field-oriented control (FOC) of 3-phase BLDC motor in column-assist EPS systems. IC Role / Device Role / Timing Role: Primary angle sensor providing 15-bit absolute position and angular velocity to MCU for torque/current loop closure. Use Value: ±1.0° accuracy over full automotive temperature range ensures consistent steering assist response without recalibration across vehicle life. |
Use Scenario: Monitoring throttle plate angular position in drive-by-wire gasoline engines with redundant sensing requirements. IC Role / Device Role / Timing Role: Safety-relevant angle transducer delivering PWM output with CRC-checked SSC diagnostics for fault detection. Use Value: Pre-configured E5000 mode enables direct MCU GPIO capture of angle data, reducing BOM count vs. SPI-based alternatives. |
| Transmission Gear Selector | Rotary HVAC Actuator |
|
Use Scenario: Detecting mechanical detent positions in automatic transmission shift-by-wire levers with high reliability. IC Role / Device Role / Timing Role: Absolute 360° position sensor with revolution counter enabling multi-turn gear state tracking. Use Value: Integrated autocalibration maintains accuracy despite under-hood thermal cycling, eliminating periodic re-zeroing procedures. |
Use Scenario: Closed-loop positioning of blend-air doors in automotive HVAC modules using compact DC motors. IC Role / Device Role / Timing Role: Low-power, high-resolution angle feedback device interfacing directly to motor driver IC via PWM. Use Value: PG-DSO-8 package with thermal pad ensures stable operation at 150°C ambient near heater cores without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar GMR-based angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5055A-DSOT | 14-bit resolution (0.022°), SPI-only interface, no integrated autocalibration, max 125°C junction rating. | Limited to cabin/non-engine-bay applications; lacks PWM output and SIL diagnostics. | Choose for cost-sensitive, non-safety-critical rotary encoders where 125°C suffices and SSC/PWM coexistence is unnecessary. |
| TLE5012B E1000 FUMA1 | Same die, pre-configured for incremental (IIF) quadrature output instead of PWM; identical accuracy, temp range, and diagnostics. | Used where MCU has dedicated QEI hardware and requires A/B/Z index pulses rather than analog-like PWM duty cycle. | Choose when legacy motor control firmware expects quadrature inputs and system-level timing sync is managed externally. |
Compared with AS5055A-DSOT, TLE5012BE5000FUMA1 offers higher resolution, extended temperature capability, and safety-ready interfaces; versus E1000, it trades quadrature timing flexibility for single-wire PWM simplicity and reduced MCU resource usage.

FAQ
What interface modes does TLE5012BE5000FUMA1 support out-of-the-box?
This part is factory pre-configured as an E5000 derivative, meaning its primary output is a single-wire PWM signal encoding absolute angle (0°–360° as 0%–100% duty cycle). The SSC interface remains fully accessible for configuration, diagnostics, and register access - both operate concurrently without conflict.
Does TLE5012BE5000FUMA1 require external calibration during system integration?
No external calibration is required. The device ships pre-calibrated with laser-fused parameters stored in on-chip fuses. An optional on-chip auto-calibration algorithm further compensates for long-term drift and temperature effects, maintaining ±1.0° accuracy over lifetime without user intervention.
Can TLE5012BE5000FUMA1 be used in systems requiring functional safety compliance?
Yes. It supports ASIL-B per ISO 26262 through integrated diagnostics including CRC-8 on SSC, CRC-4 on SPC, BIST for CORDIC/ADC/ISM, and supply monitoring (VDD/GND off-detection). These features are documented in Infineon's safety manual and certified by TÜV SÜD.
How does the E5000 configuration differ from other TLE5012B derivatives like E1000 or E9000?
E5000 configures CSQ as a PWM output pin; E1000 configures IFA/IFB as quadrature A/B outputs; E9000 configures CSQ for Short PWM Code (SENT-based) output. All share identical core sensing performance, temperature range, and safety features - only interface mapping and default register settings differ.
