The Infineon TLE4803 is an inductive sensor IC designed for angular position sensing in automotive applications, specifically targeting linear position and steering angle sensors[cite: 1035, 1036]. It operates using the eddy current method to sense the position of a metallic target placed above PCB printed coils[cite: 1051]. The TLE4803 incorporates a digital signal processing unit (DSP) for signal compensation and angle calculation[cite: 1052]. It offers SENT (based on SAE J2716-2016) and SPC interfaces for flexible use cases[cite: 1030, 1053].
Key features of the TLE4803 include inductive-based measurement and angle measurements derived from two internally processed angles[cite: 1026, 1027]. It is intrinsically robust against stray fields, complying with ISO 11452-8:2015[cite: 1028]. The device is an ISO 26262:2018 Safety Element out of Context, suitable for safety requirements up to ASIL D[cite: 1029]. It is available in a PG-TSSOP-16 SMD package, rated for an ambient temperature range of -40°C to 150°C[cite: 1031]. The TLE4803 also includes overvoltage and reverse polarity protection, integrated memory for calibration and configuration, and is RoHS compliant and halogen-free[cite: 1031, 1032, 1033]. The product has been validated according to AEC-Q100, Grade 0, making it qualified for automotive applications[cite: 1041, 1042].
