Infineon Technologies TLI5590A6WXTMA1

Overview

TLI5590A6WXTMA1 from Infineon Technologies is a two-channel ratiometric TMR-based magnetic gradiometer for high-precision linear position sensing, featuring differential sine/cosine outputs, ±5 mT magnetic field range, 5 kHz bandwidth, and operation from -40°C to 125°C in an SG-WFWLB-6-3 wafer-level package (1.27 × 0.93 × 0.4 mm). It enables sub-micron resolution length measurement with multipole stripe magnets in lens actuation systems.

For engineers reviewing the TLI5590A6WXTMA1 datasheet, TLI5590A6WXTMA1 pinout, TLI5590A6WXTMA1 application, or TLI5590A6WXTMA1 equivalent, this device supports high-accuracy incremental position feedback in space-constrained industrial and optical modules where thermal stability, ratiometric output fidelity, and TMR bridge linearity are critical selection criteria.

Technical Context

The TLI5590A6WXTMA1 integrates two discrete, factory-linearized tunnel magnetoresistance (TMR) Wheatstone bridges oriented orthogonally to generate true differential sine and cosine analog outputs. Its ratiometric architecture ensures output voltage scaling directly proportional to VDD, eliminating supply-induced gain error.

Each bridge responds to orthogonal components of magnetic flux density along the x- and y-axes; combined signal processing enables robust relative position tracking independent of magnet strength variation. The device operates with no internal ADC or digital logic-output signals require external conditioning and interpolation.

FAQ

What magnet type and configuration is required for optimal performance?

The TLI5590A6WXTMA1 requires a multipole stripe magnet with alternating north-south poles aligned parallel to the sensitive axis. Pole pitch must match the sensor's spatial period (typically 1–2 mm); magnet surface field should be within ±5 mT at the sensor location. Magnet placement must follow the sensitive area geometry shown in Figure 3 of the datasheet.

Does the device include internal signal conditioning or interpolation?

No. The TLI5590A6WXTMA1 provides raw differential analog sine and cosine outputs only. All signal conditioning-including amplification, filtering, ADC conversion, and arctangent interpolation-must be implemented externally. The application circuit in Figure 4 shows recommended buffer capacitor placement for bandwidth control.

How is the ratiometric behavior implemented and why does it matter?

Ratiometric operation means both output amplitudes scale linearly with VDD. This eliminates gain error caused by supply voltage variation, which is critical in battery-powered devices where VDD may drop from 4.2 V to 3.2 V. The ratio VP1/VN1 and VP2/VN2 remains constant regardless of VDD, preserving position calculation accuracy.

Can this sensor be used for absolute position measurement?

No-it is designed exclusively for incremental (relative) position sensing. Output signals repeat every pole pitch; absolute position requires external homing or multi-turn encoding. For absolute linear position, Infineon's TLI4971 or TLV493D families would be appropriate alternatives.
