Product details
Overview
TLE5309DE2211XUMA1 from Infineon Technologies is a dual-die, AEC-Q100 qualified contactless angle sensor combining a top-mounted GMR sensor (0–360° range) and bottom-mounted AMR sensor (0–180° range) in a single PG-TDSO-16 package. It delivers pre-amplified differential sine/cosine analog outputs, operates from 5.0 V supply for both sensor domains, and supports automotive-grade ambient temperatures from −40°C to +125°C. Its diverse redundancy architecture enables safety-critical applications such as electric power steering (EPS) and BLDC motor commutation.
For engineers reviewing the TLE5309DE2211XUMA1 datasheet, TLE5309DE2211XUMA1 pinout, TLE5309DE2211XUMA1 application, or TLE5309DE2211XUMA1 equivalent, this page provides verified functional identity, validated pin roles, confirmed dual-supply operation (5.0 V), true 360°/180° output ranges, and real-world use cases in EPS and actuator control systems - all derived from Infineon's official datasheet V1.1 (2017-10).
Technical Context
The device implements vertical-integrated MR sensing with two independent Wheatstone bridges per sensor: orthogonal GMR bridges yield unambiguous 360° output via arctan2(Vx,Vy), while 45°-offset AMR bridges deliver high-precision 180° output requiring arctan2(Vx,Vy)/2. Each sensor has dedicated supply (GMR_VDD, AMR_VDD), ground (dual GMR_GND/AMR_GND), and diagnostic pins (GMR_VDIAG, AMR_VDIAG).
Signal conditioning includes DC-offset compensation, temperature-compensated amplification, and fuse-protected analog paths. The flipped die configuration ensures spatial alignment of sensitive areas, minimizing magnetic field orientation deviation between GMR and AMR elements - critical for cross-sensor validation in ASIL-B/C systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE5309DE1211XUMA1 | 3.3 V supply for both GMR and AMR domains - lower power but reduced noise margin vs. 5.0 V variant. | Preferred in 3.3 V system architectures with tight power budgets; not suitable for legacy 5 V motor control boards. | Select when system supply is fixed at 3.3 V and SNR requirements permit lower output amplitude. |
| TLE5309DE5201XUMA1 | Mixed supply: GMR at 3.3 V, AMR at 5.0 V - asymmetric operation for hybrid signal chain optimization. | Used where AMR precision demands higher supply headroom but GMR can operate at lower voltage for efficiency. | Choose when optimizing for AMR accuracy while minimizing total system power - requires dual-rail PCB design. |
Compared with TLE5309DE2211XUMA1, the E1211 variant trades output dynamic range for lower quiescent current, while the E5201 offers granular supply control at the cost of increased layout complexity - making E2211 the default choice for new 5 V automotive designs requiring simplicity and robustness.

FAQ
What is the function of GMR_VDIAG and AMR_VDIAG pins?
GMR_VDIAG and AMR_VDIAG are analog diagnostic outputs proportional to their respective die temperatures. They enable real-time thermal monitoring for fault detection and on-the-fly compensation. Each pin is internally connected to its sensor's bridge voltage and requires no external components - used directly by MCU ADCs to validate sensor health and support ISO 26262 diagnostic coverage.
Can TLE5309DE2211XUMA1 be used with a 3.3 V microcontroller ADC?
Yes - the analog outputs (e.g., GMR_SIN_P/N) are rail-to-rail compatible and designed to use the same 5.0 V supply as the sensor's voltage reference. When interfaced with a 3.3 V ADC, an external resistor divider or level-shifting amplifier is required to scale the 0–5 V output range to 0–3.3 V without degrading SNR or introducing offset errors.
How does the flipped dual-die configuration improve accuracy?
The flipped configuration places the GMR (top) and AMR (bottom) sensitive areas in near-identical positions within the package plane. This minimizes angular deviation between sensed magnetic field vectors - reducing systematic misalignment error to <0.5° - which is critical for cross-sensor validation in safety-critical angle computation.
Is external filtering required on the sine/cosine outputs?
No external RC filtering is required for basic operation - the internal amplifiers include optimized bandwidth limiting (≈1 MHz) and ESD protection. However, for high-EMI environments (e.g., near inverters), a 100 Ω series resistor + 100 pF capacitor at each output improves RF immunity without affecting phase response up to 100 kHz.
