Product details
Overview
TLE5309DE5201XUMA1 from Infineon Technologies is a dual-die, diverse-redundant analog angle sensor integrating one GMR sensor (top die) and one AMR sensor (bottom die) in a single PG-TDSO-16 package. It delivers independent 360° sine/cosine outputs from the GMR channel and 180° (doubled-angle) sine/cosine outputs from the AMR channel, with separate 5.0 V (GMR) and 3.3 V (AMR) supplies, -40°C to 125°C operation, and AEC-Q100 Grade 1 qualification for automotive safety-critical systems.
For engineers reviewing the TLE5309DE5201XUMA1 datasheet, TLE5309DE5201XUMA1 pinout, TLE5309DE5201XUMA1 application, or TLE5309DE5201XUMA1 equivalent, key selection considerations include dual-supply rail configuration (5 V/3.3 V), differential analog output compatibility, magnetic field immunity, fast power-on time (<10 µs), and functional redundancy for ASIL-B/C system compliance.
Technical Context
The device implements vertical-integrated MR sensing: four Wheatstone bridges per sensor-orthogonal for GMR (enabling full 360° unambiguous measurement) and 45°-offset for AMR (delivering 180° range with doubled-angle internal computation). Each bridge's resistance change responds directly to magnetic field vector orientation, not strength, ensuring airgap insensitivity.
GMR and AMR dies are flip-chip mounted on opposite sides of the same lead frame, aligning sensitive areas in the package plane to minimize magnetic field vector deviation between channels. Signal conditioning includes DC-offset correction, temperature-compensated amplification, and dedicated diagnostic outputs (GMR_VDIAG, AMR_VDIAG) proportional to bridge voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Range (GMR) | 0–360° continuous, unambiguous output via orthogonal sine/cosine bridges - enables absolute rotor position without index pulse. |
| Angle Range (AMR) | 0–180° (internal 0–360° doubled-angle measurement, halved in post-processing) - provides high-precision interpolation within half-cycle. |
| Supply Configuration | Independent GMR_VDD = 5.0 V ±10%, AMR_VDD = 3.3 V ±10% - allows optimized noise performance and dynamic range per sensor type. |
| Output Type | Differential analog sine/cosine pairs (GMR_SIN_P/N, GMR_COS_P/N, AMR_SIN_P/N, AMR_COS_P/N) - supports ratiometric ADC interfacing with shared supply as reference. |
| Operating Temperature | -40°C to +125°C ambient - qualified per AEC-Q100 Grade 1, enabling use in EPS, BLDC actuators, and transmission control units. |
| Power-On Time | <10 µs - enables ultra-low average power via rapid power cycling in turn-counting or wake-up applications. |
| Diagnostic Outputs | GMR_VDIAG and AMR_VDIAG - bridge-voltage-derived analog signals for real-time temperature monitoring and fault detection. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GMR_VDIAG | Analog diagnostic output proportional to GMR bridge voltage - used for temperature tracking and open-circuit detection. |
| 2 | GMR_VDD | 5.0 V supply input for GMR sensor die - decoupling required near pin for EMI suppression and transient stability. |

| 7 | AMR_VDD | 3.3 V supply input for AMR sensor die - isolated from GMR supply to prevent cross-talk and optimize SNR. |
| 8 | AMR_VDIAG | Analog diagnostic output proportional to AMR bridge voltage - enables independent thermal monitoring of bottom die. |
| 9,10 | AMR_GND | Dedicated ground return for AMR die - separated from GMR ground to avoid shared-impedance coupling and maintain channel independence. |
| 11 | AMR_COS_N | Negative differential cosine output from AMR bridge - used with AMR_COS_P for 180° angle reconstruction. |
| 12 | AMR_COS_P | Positive differential cosine output from AMR bridge - completes cosine differential pair for AMR channel. |
| 13 | GMR_COS_P | Positive differential cosine output from GMR bridge - forms full 360° cosine pair with GMR_COS_N. |

Key Features
| Feature | Design Value |
|---|---|
| Dual-die flipped configuration | Co-planar sensitive areas of GMR (top) and AMR (bottom) dies minimize magnetic field vector misalignment - critical for cross-channel consistency in safety validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output analog angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE5309DE1211XUMA1 | Both GMR and AMR supplied at 3.3 V; includes Temperature Compensation Offset (TCO) calibration. | Better suited for cost-sensitive, non-safety-critical applications where unified supply simplifies PCB layout. | Select when system-level supply is limited to 3.3 V and TCO-enhanced accuracy over temperature is prioritized over supply flexibility. |
| TLE5309DE2211XUMA1 | Both GMR and AMR supplied at 5.0 V; includes Temperature Compensation Offset (TCO) calibration. | Optimized for legacy 5 V architectures with higher noise margin but reduced AMR SNR vs. 3.3 V operation. | Choose when existing 5 V infrastructure dominates and TCO-driven accuracy is required across full temperature range. |
Compared with TLE5309DE5201XUMA1, the E1211 variant trades supply flexibility for lower BOM count and enhanced TCO accuracy, while the E2211 variant maintains 5 V compatibility across both dies but sacrifices AMR signal-to-noise ratio versus the mixed-rail E5201 configuration.

FAQ
What is the purpose of separate GMR_VDD and AMR_VDD pins?
The separate supply pins enable independent biasing of the GMR (5.0 V) and AMR (3.3 V) sensor dies to optimize signal-to-noise ratio, dynamic range, and power efficiency per technology. GMR benefits from higher supply for improved sensitivity and linearity, while AMR achieves better resolution and lower thermal drift at 3.3 V - a configuration validated in Infineon's AEC-Q100 test reports.
How does the flipped dual-die architecture improve functional safety?
Mounting the GMR die on top and AMR die on bottom of the same lead frame - with aligned sensitive areas - minimizes magnetic field vector deviation between channels. This physical co-location ensures highly correlated yet technologically diverse measurements, satisfying ISO 26262 requirements for plausibility checking and fault detection in ASIL-B/C systems.
Can TLE5309DE5201XUMA1 be used with a single 5 V supply?
No - the AMR die requires a regulated 3.3 V supply (AMR_VDD), and applying 5 V will exceed its absolute maximum rating and cause permanent damage. A dedicated 3.3 V LDO or DC-DC converter must supply pin 7 (AMR_VDD), while pin 2 (GMR_VDD) accepts 5.0 V ±10%. The datasheet explicitly prohibits shared supply routing.
What is the role of GMR_VDIAG and AMR_VDIAG pins?
GMR_VDIAG (pin 1) and AMR_VDIAG (pin 8) output analog voltages proportional to their respective MR bridge supply currents, serving as real-time diagnostics for open-circuit, short-circuit, and thermal derating conditions. These signals are internally temperature-compensated and calibrated - enabling hardware-level fault detection without MCU intervention.
