Infineon Technologies TLI4906LHALA1

Overview

TLI4906LHALA1 from International Rectifier / Infineon is a Hall-effect magnetic switch sensor in a 3-SSIP, SSO-3-02 package. It provides a digital magnetic switching output for contactless position, speed, or proximity detection where a mechanical contact would add wear or contamination risk.

For engineers reviewing the TLI4906LHALA1 datasheet, TLI4906LHALA1 pinout, TLI4906LHALA1 application, or TLI4906LHALA1 equivalent, this device is commonly used in position detection, speed and rotation sensing, automotive sensor assemblies, and service replacement designs. The sensor is normally mounted so that the magnetic field crosses the sensing area at the required operating point. Package orientation, air gap, magnet strength, and supply decoupling must be checked against the technical documentation switching thresholds.

Technical Context

In a board-level sensing circuit, TLI4906LHALA1 connects to a supply rail, ground, and a digital output line. The output is read by a microcontroller or logic input, while the magnetic threshold is determined by the Hall element and internal comparator.

Mechanical placement is part of the electrical design: magnet polarity, distance, target movement, and PCB tolerances determine whether the device reliably changes state across temperature and vibration.

For replacement, the switching threshold, output structure, package orientation, and temperature grade must match the original sensor. A similar Hall switch in a different package can change the magnetic trip point in the final assembly.

Key Specifications

Pinout & Package

The TLI4906LHALA1 pinout must be reviewed from the exact package drawing because terminal function, thermal path, and mechanical footprint are linked in this product family. 3-SSIP, SSO-3-02 package information and Bulk packaging for this line.

For PCB design, use the package drawing and confirm copper area, soldering method, creepage or clearance where applicable, and the final orderable suffix before layout or replacement approval. SIP / PowerSIP module package intended for vertical mounting and controlled creepage layout.

Key Features

• Hall-effect magnetic switch sensor for contactless magnetic position or speed detection.
• Digital output simplifies MCU or logic input connection.
• Small SSO-style package supports compact sensor placement near a magnet or rotating target.
• No mechanical contact wear, suitable for long-life sensing assemblies.
• Switching threshold, magnet polarity, and air gap must match the final mechanical design.
• Supply decoupling and routing improve immunity in automotive or industrial wiring.

Applications

Equivalent & Alternatives

When evaluating TLI4906LHALA1 equivalent devices, engineers should compare only specific orderable alternatives and should verify package footprint, pinout, electrical ratings, thermal data, qualification status, and suffix or packing requirements before substitution.

No confirmed orderable alternative orderable device is listed in the production data for TLI4906LHALA1. Use a direct substitute only after confirming the original technical documentation ratings and the replacement part technical documentation at the circuit level.

Compared with related alternatives, TLI4906LHALA1 should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

TLI4906LHALA1 should be sourced as original International Rectifier / Infineon inventory through traceable and controlled supply channels. Quality verification may include package inspection, top-mark validation, label and lot review, solderability inspection, moisture-sensitivity handling review, and electrical screening according to the target production requirement.

Because TLI4906LHALA1 is used in magnetic position and speed sensing circuits, final validation should include the actual PCB footprint, thermal path, electrical stress, operating temperature, and fault-condition behavior. Traceable sourcing helps reduce counterfeit risk and supports repeatable performance in production, repair, and maintenance programs.

Availability

TLI4906LHALA1 available at Aetrix Electronics and suitable for magnetic position and speed sensing circuits requiring stable component supply, package matching, and controlled replacement planning.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, repair programs, and electronics production teams.

For production or repair deployment, confirming package type, orderable suffix, lifecycle status, environmental requirement, electrical rating, thermal condition, and sourcing continuity helps reduce procurement risk and improve manufacturing stability.

Manufacturer

International Rectifier was a semiconductor manufacturer known for power MOSFETs, IGBTs, gate drivers, power-management ICs, intelligent power switches, photovoltaic relays, and power modules. International Rectifier products became part of Infineon Technologies' power semiconductor portfolio after the acquisition of International Rectifier.

The TLI4906LHALA1 ordering line should be reviewed with the relevant International Rectifier legacy technical documentation and Infineon supply-chain references where available. This is especially important for legacy MOSFETs, IRAM modules, PV relay products, and automotive AUIR power devices.

FAQ

What is TLI4906LHALA1 used for?

TLI4906LHALA1 is used in magnetic position and speed sensing circuits. The exact application depends on the technical documentation electrical ratings, package, pinout, and thermal capability.

Where can I find the TLI4906LHALA1 technical documentation?

The TLI4906LHALA1 technical documentation should be obtained from International Rectifier / Infineon documentation or an authorized technical documentation source. It should be used to confirm ratings, package information, pinout, thermal data, and test conditions.

What should be considered in TLI4906LHALA1 pinout design?

Pinout design should confirm the package drawing, terminal functions, thermal path, high-current routing or isolation spacing, and whether the orderable suffix changes package or packing details.

Can TLI4906LHALA1 be used as a direct replacement?

TLI4906LHALA1 can be used as a direct replacement only when the package footprint, pinout, electrical ratings, thermal behavior, and qualification status match the original design.

What are common TLI4906LHALA1 equivalent solutions?

Equivalent solutions should be limited to specific orderable devices with verified technical documents. Suffix variants may differ in package, reel orientation, lead finish, qualification, or manufacturing status.
