Product details

Overview

TLE5309DE1211XUMA1 from Infineon is a dual-die, AEC-Q100 qualified contactless angle sensor integrating a top-side GMR sensor (360° range) and bottom-side AMR sensor (180° high-precision range) in one PG-TDSO-16 package. It delivers differential sine/cosine analog outputs for both sensors, operates from separate 3.3 V supplies (GMR and AMR), and supports automotive-grade ambient temperatures from −40°C to +125°C. Used in electric power steering (EPS) and BLDC motor commutation where redundancy, low propagation delay, and airgap immunity are critical.

For engineers reviewing the TLE5309DE1211XUMA1 datasheet, TLE5309DE1211XUMA1 pinout, TLE5309DE1211XUMA1 application, or TLE5309DE1211XUMA1 equivalent, this page provides verified technical context, validated pin functions, real-world use cases in safety-critical motion control, and confirmed alternative parts with documented functional and supply-voltage differences.

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(V_X,V_Y); 45°-offset AMR bridges produce 180° output requiring arctan2(V_X,V_Y)/2. Each die 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. Output voltages are rail-to-rail referenced to their respective supply rails-enabling direct interfacing with 3.3 V ADCs without external level-shifting-and maintain amplitude stability across airgap variations due to MR physics.

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
TLE5309DE2211XUMA1	GMR and AMR both supplied at 5.0 V (vs. 3.3 V in E1211)-higher output swing but requires 5 V LDO and higher power budget.	Suitable for legacy 5 V ADC systems; not drop-in compatible due to supply voltage mismatch and different TCO calibration.	Select only if existing 5 V supply infrastructure exists and 3.3 V regulator redesign is prohibitive.
TLE5309DE5201XUMA1	GMR supplied at 3.3 V, AMR at 5.0 V; no Temperature Compensation Offset (TCO) calibration-higher angle error drift above 85°C.	Used in cost-sensitive non-safety applications where full AEC-Q100 Grade 1 thermal performance is not required.	Acceptable for interior modules (e.g., climate control flaps) but not for EPS or drivetrain systems.

Compared with TLE5309DE1211XUMA1, the E2211 variant trades lower system-level power efficiency for compatibility with 5 V signal chains, while the E5201 sacrifices thermal stability and safety certification to reduce BOM cost-making E1211 the only choice for ASIL-B–compliant, 3.3 V–based automotive motion control.

FAQ

What is the purpose of separate GMR_VDD and AMR_VDD pins?

The dual supply pins enable independent power sequencing, fault isolation, and flexible system-level power architecture. For example, the AMR die can remain powered during GMR self-test, or one sensor can be cycled to reduce average current. This separation also prevents supply coupling noise from degrading the high-precision AMR channel.

How does the flipped dual-die configuration improve accuracy?

Mounting the GMR die on top and AMR die on bottom-flipped so their sensitive areas align in the same XY plane-minimizes mechanical misalignment between sensing elements. This ensures both sensors experience nearly identical magnetic field vectors, reducing cross-die angle error to <1° and enabling robust hardware-level redundancy validation.

Can TLE5309DE1211XUMA1 interface directly with a 3.3 V ADC?

Yes. All analog outputs (GMR_SIN_P/N, AMR_COS_P/N, etc.) are ratiometric to their respective 3.3 V supplies, producing 0–3.3 V differential signals. When referenced to the same 3.3 V ADC VREF, they fully utilize the converter's dynamic range without external scaling or level-shifting circuitry.

What diagnostic capabilities does TLE5309DE1211XUMA1 provide?

It offers two dedicated diagnostic outputs: GMR_VDIAG and AMR_VDIAG deliver temperature-proportional voltages from each die's bridge-enabling real-time thermal monitoring and plausibility checks. Combined with output amplitude and phase consistency between sine/cosine pairs, these signals support ISO 26262-compliant fault detection strategies.
