Product details
Overview
TLE72592GEXUMA4 from Infineon Technologies is a single-wire LIN transceiver for automotive in-vehicle networks, functioning as the physical layer interface between microcontroller protocol logic and the LIN bus. It supports data rates up to 20 kBaud, complies with LIN specifications 1.2 through 2.2A, operates from 12 V or 24 V board nets, and delivers <8 µA quiescent current in Sleep mode while retaining bus and local wake-up capability.
For engineers reviewing the TLE72592GEXUMA4 datasheet, TLE72592GEXUMA4 pinout, TLE72592GEXUMA4 application, or TLE72592GEXUMA4 equivalent, key selection criteria include LIN 2.2A compliance, dual-voltage (3.3 V/5 V) logic compatibility, integrated overtemperature and under-voltage protection, bus short-to-battery/ground handling, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE72592GEXUMA4 implements a bipolar-CMOS-DMOS Smart Power Technology (SPT®) architecture, enabling robust integration of analog control, digital logic, and high-side bus driver stages on a single die. Its receiver includes an integrated noise filter for EMI immunity, while the transmitter features programmable slew-rate control for EME reduction across 2.4–20 kBaud.
Three primary operating modes-Normal (with Normal Slope and Flash submodes), Stand-By, and Sleep-are controlled via the EN pin. The INH output enables external voltage regulator control and master-node bus termination switching, and the device supports wake-up detection on both BUS and WK pins with negative-edge triggering and source identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VS = 5.5 V to 27 V - supports direct connection to 12 V and 24 V automotive battery nets without external regulation. |
| Logic I/O Compatibility | 3.3 V and 5 V microcontrollers - eliminates level-shifting circuitry for mixed-voltage ECUs. |
| Sleep Mode Current | <8 µA - meets stringent automotive low-power requirements for always-on LIN nodes. |
| ESD Robustness | ±11 kV HBM per IEC61000-4-2 - ensures reliability in high-noise assembly and service environments. |
| LIN Compliance | LIN 1.2, 1.3, 2.0, 2.1, 2.2, and 2.2A - guarantees interoperability across legacy and modern vehicle architectures. |
| Bus Termination | 30 kΩ internal pull-up - simplifies master-node design by eliminating external termination resistor. |
| Wake-Up Sources | BUS line activity and dedicated WK pin (negative edge) - enables selective node activation without bus-wide polling. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin SOIC with exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RxD | Receiver Data Output | Active-low LIN bus signal feedback to MCU; requires external pull-up for wake-up/power-up state indication. |
| EN | Enable Input | Active-high mode control; integrated pull-down ensures safe default Stand-By/Sleep on power-up. |
| WK | Local Wake-Up Input | Active-low, negative-edge triggered; internal pull-up enables wake-from-sleep via external switch or sensor. |
| TxD | Transmit Data Input | Active-low MCU output; strong pull-down after WK wake-up, weak pull-down after BUS wake-up or power-up. |
| GND | Ground Reference | Primary return path for VS, BUS, and logic circuits; shared with thermal pad for thermal dissipation. |
| BUS | LIN Bus Interface | Single-wire bidirectional I/O; integrates bus driver, receiver, internal termination, and short-circuit protection. |
| VS | Battery Supply Input | Direct connection to automotive battery rail; powers all internal circuitry and drives INH output. |
| INH | Inhibit Output | Battery-referenced open-drain output; controls external LDOs or master termination resistors during mode transitions. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN1029DR | Higher ESD rating (±15 kV), no integrated bus termination, requires external 30 kΩ for master use. | Lacks INH output for regulator control; not suitable for designs requiring automatic LDO enable/disable. | Select when maximum ESD margin is critical and external termination is acceptable. |
| ATA663211-TAQY | Includes integrated watchdog timer and enhanced wake-up filtering; slightly higher sleep current (12 µA). | Supports LIN FD physical layer prep; not required for standard LIN 2.x deployments. | Select when system-level fault monitoring and future LIN FD readiness are prioritized over minimal quiescent current. |
Compared with TLIN1029DR and ATA663211-TAQY, the TLE72592GEXUMA4 offers optimal balance of ultra-low sleep current, integrated bus termination, and INH-controlled power management-making it ideal for cost-sensitive, space-constrained automotive nodes where power sequencing and master-node simplicity are essential.

FAQ
What is the function of the INH pin on the TLE72592GEXUMA4?
The INH (Inhibit) pin is a battery-referenced open-drain output that goes HIGH (to VS) in Normal and Stand-By modes. It is used to enable external voltage regulators or control master-node bus termination resistors. During Sleep mode, INH floats, allowing downstream regulators to be powered down and reducing system-level quiescent current.
How does the TLE72592GEXUMA4 handle wake-up events from the LIN bus?
The device detects dominant bus activity and triggers wake-up automatically. Upon bus wake-up, RxD goes LOW and TxD enters weak pull-down (350 kΩ) state. The MCU must monitor RxD to distinguish bus wake-up from local WK-pin wake-up, which sets TxD to strong pull-down (>1.5 mA) and also pulls RxD LOW.
Is an external pull-up resistor required on the RxD pin?
Yes-an external pull-up resistor to the MCU's I/O supply (3.3 V or 5 V) is mandatory. It ensures RxD reads HIGH during power-up and after bus wake-up, and allows the MCU to detect wake-up source (RxD LOW after WK wake-up vs. RxD LOW after BUS wake-up with specific TxD behavior).
What LIN specification versions does the TLE72592GEXUMA4 support?
The TLE72592GEXUMA4 is compliant with LIN specifications 1.2, 1.3, 2.0, 2.1, 2.2, and 2.2A. It supports all mandatory electrical characteristics-including bus voltage levels, timing tolerances, and fault behavior-for full interoperability across legacy and current-generation automotive LIN networks.
