Product details
Overview
TLE4242GATMA3 from Infineon Technologies is a high-side LED driver IC with integrated LIN transceiver, 500 mA output current capability, ±1% current accuracy over temperature, and TO-263-7 (D²PAK) package; used in automotive exterior lighting control where LIN bus communication and precise constant-current drive are required.
For engineers reviewing the TLE4242GATMA3 datasheet, TLE4242GATMA3 pinout, TLE4242GATMA3 application, or TLE4242GATMA3 equivalent, key selection criteria include LIN physical layer compliance (ISO 17987-2), programmable PWM dimming frequency up to 25 kHz, thermal shutdown with hysteresis, and diagnostic reporting via LIN frame.
Technical Context
The TLE4242GATMA3 integrates a high-side switch with current-sense amplifier and a full-duplex LIN 2.2A transceiver in a single monolithic die. It supports LIN slave node operation with configurable wake-up detection and error signaling via dedicated status pins.
Its current regulation loop uses an external sense resistor and internal 1.25 V reference, enabling accurate 500 mA output with <±1% tolerance from -40°C to 150°C. The device operates from 5.5 V to 40 V supply and includes reverse-battery protection and load-dump immunity per ISO 7637-2 Pulse 5a.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side LED driver with LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLD5098EL | Higher 1.5 A output, no integrated LIN transceiver (requires external TJA1020) | Requires additional LIN PHY and routing; better suited for non-LIN or higher-current designs | Select when >500 mA drive or separate LIN PHY architecture is preferred |
| ASL3416SHN | Includes SPI interface instead of LIN; 600 mA output; different fault reporting protocol | Designed for CAN-based body domains; not LIN-compatible without gateway translation | Select for SPI-controlled systems or where CAN infrastructure already exists |
Compared with TLD5098EL and ASL3416SHN, the TLE4242GATMA3 uniquely combines LIN 2.2A compliance, 500 mA drive, and diagnostic reporting in one package-enabling drop-in replacement in existing LIN-based lamp modules without redesigning communication or power stages.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLE4242GATMA3 has a maximum junction temperature of 175°C, with thermal shutdown activating at that threshold and releasing at 150°C due to 25°C hysteresis. Continuous operation at rated 500 mA requires proper PCB copper area (≥200 mm² thermal pad) and ambient temperature ≤85°C to maintain safe thermal margin.
Does the device support LIN sleep mode and local wake-up?
Yes, the TLE4242GATMA3 supports LIN sleep mode with ultra-low quiescent current (<15 µA) and local wake-up via VBAT edge detection. It meets LIN specification requirements for slave node wake-up latency (<100 ms) and supports automatic transition between active and sleep states without host intervention.
Can IS pin output be used for closed-loop current regulation?
The IS pin provides a buffered, ratiometric analog voltage (1.25 V per 500 mA) referenced to GND. While it is intended for monitoring and diagnostics, it can feed an external comparator or ADC for closed-loop control-provided external circuitry respects the 10 µA max sink/source limit and avoids loading the pin beyond datasheet-specified capacitance (≤100 pF).
Is the TO-263-7 package lead-free and RoHS-compliant?
Yes, the TLE4242GATMA3 in TO-263-7 package is manufactured with lead-free terminations and fully complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The package marking "GATMA3" denotes green (halogen-free) and RoHS-compliant material set per Infineon's product change notification PCN-2021-003.
