Product details
Overview
TLE72593LEXUMA1 from Infineon Technologies is a single-wire LIN transceiver compliant with ISO 17987-4 and LIN Specifications 2.2A, designed as the physical layer interface between automotive microcontrollers and the LIN bus. It supports data rates up to 20 kbps, operates from 5 V to 27 V supply, draws ≤8 µA in sleep mode, and features integrated wake-up via BUS or WK pin for battery-sensitive body electronics applications.
For engineers reviewing the TLE72593LEXUMA1 datasheet, TLE72593LEXUMA1 pinout, TLE72593LEXUMA1 application, or TLE72593LEXUMA1 equivalent, key selection criteria include LIN 2.2A compliance, dual-voltage logic compatibility (3.3 V/5 V), dominant time-out protection, BUS short-to-VBAT/GND handling, and AEC-Q100 qualification for under-hood and interior modules.
Technical Context
The TLE72593LEXUMA1 implements a fully integrated LIN physical layer with configurable slew-rate control-Normal Slope mode for standard communication (≤20 kbps) and Flash mode for accelerated MCU programming. Its receiver includes noise-filtering circuitry and delay symmetry optimization to improve signal integrity across temperature and voltage variations.
Mode transitions are controlled exclusively by the EN pin, with INH output enabling external regulator control and master-node bus termination switching. Wake-up detection occurs on both BUS (LIN traffic) and WK (local edge-triggered) inputs, with RxD polarity inversion signaling wake events to the host controller.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Voltage Range | 5 V to 27 V - supports 12 V and 24 V automotive board nets without external regulation |
| Sleep Current | ≤8 µA typical - enables always-on partial-network operation with minimal battery drain |
| LIN Data Rate | Up to 20 kbps - meets LIN 2.2A timing requirements for body control and sensor networks |
| Logic Compatibility | 3.3 V and 5 V I/O - interfaces directly with common automotive MCUs without level-shifting |
| ESD Robustness | ±15 kV HBM per IEC61000-4-2 - eliminates need for external TVS in most ECU designs |
| Thermal Protection | Integrated overtemperature shutdown - prevents latch-up during sustained bus fault conditions |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment mounting |
Pinout & Package
Package: PG-TSON-8 (leadless, thermally enhanced, AOI-compatible), 3 mm × 3 mm, 0.65 mm pitch, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RxD | Receive data output | Active-low LIN bus signal replica; requires external pull-up for wake-up indication |
| EN | Enable input | CMOS-compatible enable; internal pull-down; HIGH activates Normal/Sleep modes |
| WK | Local wake input | Edge-triggered, active-low; internal pull-up; initiates wake from Sleep/Stand-By |
| TxD | Transmit data input | CMOS-compatible; LOW drives dominant bus state; includes timeout protection |
| GND | Ground reference | Power and signal return; connected to thermal pad for thermal dissipation |
| BUS | LIN bus interface | Single-wire bidirectional I/O with internal termination and short-circuit protection |
| VS | Battery supply input | 5–27 V primary power rail; powers internal regulators and output stage |
| INH | Inhibit output | Battery-referenced open-drain output; controls external regulators or master termination |
Key Features
| Feature | Design Value |
|---|---|
| Flash Mode Slew Rate | Accelerated edge rate for fast MCU flash programming without violating LIN timing margins |
| Dominant Time-Out | Hardware-enforced TxD dominant duration limit prevents bus lock-up during firmware faults |
| BUS Short Protection | Automatic recovery from BUS-to-VBAT or BUS-to-GND shorts without latch-up or damage |
| EMC Optimized Driver | Controlled rise/fall times reduce broadband emissions while maintaining signal integrity |
| Supply Undervoltage Detection | Internal monitoring disables outputs below VS threshold to prevent undefined bus states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN1029DRBR | TI device with integrated 5 V LDO; no INH output; lower sleep current (3 µA) | Best suited for self-powered slave nodes where local regulation is required | Select when system-level power architecture relies on integrated LDO rather than external regulator control |
| ATA663211-GAQW | Microchip device with wake-on-data feature; higher bus voltage tolerance (40 V); no Flash mode | Preferred for 24 V commercial vehicles requiring extended overvoltage robustness | Select when operating beyond 27 V or requiring wake-on-recessive-bit detection instead of edge-triggered WK |
Compared with TLIN1029DRBR and ATA663211-GAQW, the TLE72593LEXUMA1 uniquely combines INH-controlled external power management, Flash mode for programming acceleration, and AEC-Q100 Grade 1 qualification at 125 °C ambient-making it optimal for thermally constrained master nodes in passenger car ECUs.

FAQ
What LIN protocol versions does the TLE72593LEXUMA1 support?
The TLE72593LEXUMA1 is compliant with LIN Specification Versions 1.2, 1.3, 2.0, 2.1, 2.2, and 2.2A, as well as ISO 17987-4. It supports all mandatory electrical characteristics-including dominant/recessive voltage thresholds, slew rate limits, and timing tolerances-across the full 2.4 kbps to 20 kbps data rate range.
How does the INH pin function in master versus slave node configurations?
In master node configuration, INH (set HIGH) enables external 1 kΩ termination resistor control and can drive an external 5 V LDO for MCU power. In slave node use, INH remains unconnected or pulled low; its primary role is regulator enablement-not bus termination-since slaves rely on master-supplied recessive bias.
Can the TLE72593LEXUMA1 operate without an external pull-up on RxD?
No. An external pull-up resistor to the MCU's logic supply (3.3 V or 5 V) is mandatory on RxD to ensure correct wake-up indication: RxD goes LOW after BUS or WK wake events, and HIGH after power-up. Without this pull-up, wake detection fails and logic levels become undefined during mode transitions.
What is the purpose of Flash Mode, and how is it activated?
Flash Mode provides faster bus edge rates to reduce programming time during MCU firmware updates over LIN. It is entered only from Normal Slope mode by asserting a specific pulse sequence on TxD (per datasheet Figure 12), not via EN or WK. The transceiver automatically reverts to Normal Slope mode after timeout or explicit command.
