Product details
Overview
TLE72592GEXUMA1 from Infineon Technologies is a LIN bus transceiver IC designed for automotive in-vehicle networks, functioning as the physical layer interface between microcontrollers and single-wire LIN buses. 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 with dual wake-up capability (bus and local WK pin).
For engineers reviewing the TLE72592GEXUMA1 datasheet, TLE72592GEXUMA1 pinout, TLE72592GEXUMA1 application, or TLE72592GEXUMA1 equivalent, key selection criteria include LIN 2.2A compliance, 3.3 V/5 V logic compatibility, integrated overtemperature and under-voltage protection, bus short-to-VBAT/GND handling, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE72592GEXUMA1 implements a bipolar-CMOS-DMOS Smart Power Technology (SPT®) architecture enabling robust LIN physical layer signaling with controlled slew-rate modulation for EME reduction. Its receiver includes noise-filtering circuitry and internal bus termination (30 kΩ typical), while the transmitter supports dominant/recessive state generation via TxD-driven BUS output.
Mode control is managed exclusively through the EN pin, enabling deterministic transitions among Sleep (≤8 µA), Stand-By (INH = VS), and Normal Operation modes - the latter subdivided into Normal Slope (up to 20 kBaud) and Flash (microcontroller programming) sub-modes. Wake-up detection occurs on both BUS line activity and negative-edge-triggered WK pin input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Data Rate | Up to 20 kBaud - enables full-speed LIN communication compliant with all major LIN protocol versions. |
| Sleep Current | <8 µA - meets automotive low-power network requirements during vehicle off-state. |
| ESD Robustness | ±11 kV HBM per IEC61000-4-2 - ensures reliability in harsh automotive ESD environments. |
| Logic Compatibility | 3.3 V and 5 V microcontroller I/O - eliminates level-shifter need across common MCU families. |
| Supply Range | 5.5 V to 27 V - supports 12 V and 24 V automotive battery systems with brown-out tolerance. |
| Thermal Protection | Integrated overtemperature shutdown - prevents latch-up or damage during thermal stress events. |
| Wake-Up Sources | Bus activity and local WK pin (negative edge) - enables flexible system-level power management. |
Pinout & Package
Package: PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin SOIC with exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RxD | Receive data output | Active-low signal reflecting LIN bus state; requires external pull-up for wake-up/power-up indication. |
| EN | Enable input | CMOS-compatible control pin with internal pull-down; HIGH activates normal operation. |
| WK | Local wake-up input | Negative-edge-triggered with internal pull-up; initiates wake-up from Sleep/Stand-By modes. |
| TxD | Transmit data input | Drives BUS pin; LOW forces dominant state; weak/strong pull-down behavior varies by wake-up source. |
| GND | Ground reference | Common return path for analog and digital sections; connects to PCB ground plane. |
| BUS | Single-wire LIN bus interface | Bi-directional I/O with internal termination (30 kΩ) and short-circuit protection to VBAT/GND. |
| VS | Battery supply input | Primary power rail (5.5–27 V); powers internal regulators and drives INH output. |
| INH | Inhibit output | Battery-referenced open-drain output used to enable/disable external voltage regulators or master termination. |
Key Features
| Feature | Design Value |
|---|---|
| Flash Mode support | Enables safe microcontroller firmware programming over LIN without bus disturbance via controlled slew-rate transition. |
| Integrated bus termination | 30 kΩ typical internal resistor reduces external component count and improves signal integrity in slave nodes. |
| Dual wake-up detection | Simultaneous monitoring of LIN bus traffic and dedicated WK pin allows flexible low-power system architecture. |
| Bus fault protection | Withstands short-to-VBAT and short-to-GND conditions without latch-up or permanent damage. |
| AEC-Q100 qualified | Rated for Grade 1 (−40 °C to +125 °C ambient) operation - validated for under-hood automotive use. |
Applications
| Body Control Module (BCM) | Seat Control Unit |
|---|---|
Use Scenario: Centralized control of door locks, window lifts, mirrors, and interior lighting via LIN sub-networks. IC Role / Device Role / Timing Role: Physical layer transceiver interfacing MCU to LIN bus; handles dominant/recessive signaling and wake-up event forwarding. Use Value: Enables ultra-low sleep current (<8 µA) to meet OEM static current budgets while supporting reliable bus-initiated wake-up for feature activation. | Use Scenario: Motorized seat position adjustment with feedback sensors and memory functions. IC Role / Device Role / Timing Role: LIN PHY device translating MCU commands into bus signals; provides ESD-hardened interface in high-noise cabin environment. Use Value: ±11 kV ESD robustness prevents field failures from human-body discharge during service or occupant interaction. |
| Roof Module (Sunroof/Climate) | Steering Column Switch Interface |
Use Scenario: Sunroof open/close control and HVAC actuator coordination using distributed LIN slaves. IC Role / Device Role / Timing Role: Bus driver with integrated termination and INH-controlled external regulator - simplifies power sequencing. Use Value: INH output directly enables 3.3 V LDO for MCU during Normal mode, eliminating discrete enable logic and reducing BOM count. | Use Scenario: Wiper, turn signal, and cruise control switch inputs aggregated via LIN to body domain controller. IC Role / Device Role / Timing Role: Low-leakage LIN transceiver maintaining bus integrity during partial network supply conditions. Use Value: Very low BUS pin leakage current preserves recessive bus voltage in partially powered networks, preventing false dominant detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN1029DR | Supports LIN 2.2A only; no Flash mode; 10 µA sleep current; no INH output. | Lacks bus-programming support and external regulator control; suited for basic slave nodes only. | Select when Flash mode and INH-driven power management are not required. |
| UJA1075ATW/3V3 | Includes integrated voltage regulator (3.3 V); higher sleep current (12 µA); supports LIN 2.2A and SAE J2602. | Reduces external LDO count but increases quiescent load; adds J2602 compatibility for North American platforms. | Select when system-level integration of regulated supply is prioritized over lowest sleep current. |
Compared with TLIN1029DR and UJA1075ATW/3V3, the TLE72592GEXUMA1 uniquely combines Flash mode for in-system programming, INH-controlled external power sequencing, and industry-leading 8 µA sleep current - making it optimal for master-node and low-static-current automotive designs.

FAQ
What LIN protocol versions does the TLE72592GEXUMA1 support?
The TLE72592GEXUMA1 supports LIN specifications 1.2, 1.3, 2.0, 2.1, 2.2, and 2.2A. This broad backward and forward compatibility ensures interoperability across legacy and next-generation automotive networks without firmware or hardware redesign.
How does the INH pin function in master versus slave node configurations?
In master node setups, INH (driven HIGH to VS) enables external bus termination resistors or voltage regulators; in slave nodes, it remains unused or floats. The pin's battery-referenced output simplifies power-domain control without level-shifting circuitry.
Is an external pull-up resistor required on the RxD pin, and why?
Yes - an external pull-up resistor to the MCU's VIO rail is mandatory on RxD. It ensures correct logic-high indication after power-up and enables wake-up event detection (RxD goes LOW upon BUS or WK-triggered wake-up), which is essential for low-power system state recovery.
What protection features prevent damage during automotive electrical faults?
The TLE72592GEXUMA1 integrates bus short-to-VBAT and short-to-GND protection, overtemperature shutdown, under-voltage lockout, and ±11 kV IEC61000-4-2 ESD immunity. These features eliminate the need for external TVS diodes or fuses in most LIN node implementations.
