Product details

Overview

TLE72593GEXUMA1 from Infineon Technologies is an automotive-grade LIN transceiver IC compliant with ISO 17987-4 and LIN Specification 2.2A, operating at data rates up to 20 kbps. It serves as the physical layer interface between a microcontroller and the single-wire LIN bus in vehicle networks, featuring integrated wake-up detection (via BUS or WK pin), dominant time-out protection on TxD, and 3.3 V/5 V logic compatibility. Designed for 12 V and 24 V board nets, it enables low-power sleep mode (< 8 µA quiescent current) while maintaining bus wake-up capability.

For engineers reviewing the TLE72593GEXUMA1 datasheet, TLE72593GEXUMA1 pinout, TLE72593GEXUMA1 application, or TLE72593GEXUMA1 equivalent, key selection considerations include LIN 2.2A compliance, dual-voltage I/O support, INH-controlled external regulator enablement, and PG-DSO-8 package suitability for automated optical inspection and AEC-Q100 qualified automotive deployment.

Technical Context

The TLE72593GEXUMA1 implements a Smart Power Technology (SPT®)-based analog front-end with integrated bus driver, receiver filter, temperature protection, and supply undervoltage detection. Its receiver includes noise-suppressing filtering and delay symmetry optimization, while the transmitter supports two slew-rate modes: Normal Slope (≤20 kbps) and Flash Mode (for accelerated MCU programming).

Mode control is managed exclusively via the EN pin, enabling transitions between Sleep (EN = LOW, INH floating), Stand-By (EN = LOW, INH = HIGH), and Normal Operation (EN = HIGH, INH = VS). Wake-up events-local (WK pin, negative-edge triggered) or bus-based-trigger automatic exit from Sleep mode with defined RxD/TxD states and internal pull-down configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Bus Data Rate	Up to 20 kbps - supports full LIN 2.2A timing requirements including slave response and master polling.
Sleep Current	< 8 µA typical - enables always-on network monitoring without draining battery in parked vehicles.
Logic Supply Compatibility	3.3 V and 5 V microcontroller I/O - eliminates level-shifting circuitry in mixed-voltage ECUs.
ESD Robustness	±15 kV HBM per IEC61000-4-2 - ensures reliability during assembly and field operation in harsh automotive environments.
Operating Voltage Range	5.5 V to 27 V - covers cold-crank (≥5.5 V) and load-dump (≤27 V) conditions in 12 V/24 V systems.
Wake-Up Sources	BUS line activity or WK pin (negative edge) - provides redundant wake-up paths for fail-safe ECU activation.
Thermal Protection	Integrated overtemperature shutdown - prevents latch-up or damage during sustained high-temperature operation.

Pinout & Package

Package: PG-DSO-8 (lead-free, RoHS-compliant, AEC-Q100 qualified surface-mount SOIC-8 variant 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 indication and power-up initialization.
EN	Enable input	CMOS-compatible control pin with internal pull-down; HIGH enables normal operation, LOW forces Stand-By or Sleep depending on INH state.
WK	Local wake-up input	Negative-edge-triggered interrupt input with internal pull-up; initiates wake-up from Sleep mode independent of bus traffic.
TxD	Transmit data input	CMOS input with internal pull-down; drives dominant/recessive states onto BUS; protected by TxD time-out function.
GND	Ground reference	Primary return path for all analog and digital circuits; must be low-impedance connection to chassis or system ground plane.
BUS	LIN bus interface	Single-wire bidirectional I/O with internal termination (30 kΩ typical) and short-to-battery/short-to-ground protection.
VS	Battery supply input	Direct connection to vehicle battery (5.5–27 V); powers internal regulators and drives INH output at VS potential.
INH	Inhibit output	Battery-referenced open-drain output used to enable/disable external voltage regulators or master bus termination resistors.

Key Features

Feature	Design Value
Dual-slew-rate transmission	Normal Slope (≤20 kbps) and Flash Mode (optimized for MCU flash programming) reduce EMI while preserving signal integrity.
Integrated bus termination	30 kΩ internal resistor eliminates need for external termination in slave nodes, reducing BOM count and PCB area.
Low-leakage BUS pin	< 1 µA leakage in Sleep mode - maintains partial network functionality without loading powered-down segments.
INH-controlled power management	VS-referenced INH output enables coordinated shutdown of downstream regulators and bus terminators in master configurations.
AEC-Q100 Grade 1 qualification	Rated for −40 °C to +125 °C ambient operation - validated for engine bay, body control, and lighting module deployments.

Applications

IC Role / Device Role / Timing Role: LIN physical layer transceiver interfacing MCU to distributed sensors/actuators; handles wake-up on key-fob signal or door contact.

Use Value: Enables <8 µA sleep current to meet OEM battery drain targets while supporting reliable local (WK pin) and bus-initiated wake-up.

Use Scenario: Integration of sunroof position sensor, ambient light sensor, and LED map lights into a single roof-mounted ECU.

IC Role / Device Role / Timing Role: Slave-node LIN transceiver providing isolated, EMC-robust communication with BCM master; uses internal 30 kΩ termination.

Seat Control Unit

Front Lighting Control

Use Scenario: Motorized seat position memory and heating control using LIN-connected potentiometers and relays.

IC Role / Device Role / Timing Role: LIN transceiver with Flash Mode support for in-vehicle reprogramming of seat MCU firmware over the LIN bus.

Use Value: Reduces service time by enabling field updates without disassembly; Flash Mode slew rate minimizes bus disturbance during programming.

Use Scenario: Adaptive front-lighting system (AFS) communicating headlamp angle and status to central gateway via LIN.

IC Role / Device Role / Timing Role: Master-node transceiver driving LIN bus with controlled 30 kΩ termination and INH-enabled external regulator for LED drivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LIN transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLIN1029DR	TI device with integrated 5 V LDO, no INH output, lower ESD rating (±8 kV)	Lacks bus-controlled power management; unsuitable where external regulator coordination is required	Select when system-level power architecture uses centralized regulation and cost sensitivity outweighs INH flexibility
ATA663211-GAQW	Microchip device with wake-up via LIN only (no WK pin), higher sleep current (15 µA)	No local hardware wake-up path; requires bus traffic to initiate recovery from deep sleep	Select for slave-only nodes where local interrupt sources are absent and ESD robustness is secondary to footprint

Compared with TLIN1029DR and ATA663211-GAQW, the TLE72593GEXUMA1 uniquely combines INH-driven power orchestration, ±15 kV ESD immunity, and dual wake-up capability-making it optimal for master nodes requiring coordinated subsystem power control and high-reliability field operation.

FAQ

What LIN protocol versions does the TLE72593GEXUMA1 support?

The TLE72593GEXUMA1 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 standard baud rates from 2.4 kbps to 20 kbps and meets all electrical and timing requirements for master and slave node implementations under these specifications.

How does the INH pin function in master versus slave configurations?

In master configurations, INH (driven to VS) enables external voltage regulators and controls master bus termination resistors. In slave configurations, INH remains unused or can be left unconnected, as the device relies on internal 30 kΩ termination and draws power directly from VS without regulating downstream supplies.

Can the TLE72593GEXUMA1 operate with both 3.3 V and 5 V microcontrollers simultaneously?

Yes-the TLE72593GEXUMA1's TxD and RxD pins are compatible with both 3.3 V and 5 V logic levels. The transceiver itself operates from VS (5.5–27 V), and its digital I/O interfaces tolerate either voltage domain without level shifters, simplifying integration in mixed-voltage ECUs.

What is the purpose of Flash Mode and how is it activated?

Flash Mode optimizes the BUS slew rate for reduced electromagnetic emissions during external microcontroller firmware programming over LIN. It is entered from Normal Slope mode by asserting a specific sequence on the TxD pin (as defined in the datasheet), and automatically disables the output stage during transition to prevent bus corruption.
