Product details

Overview

TLE72593GEXUMA3 from Infineon Technologies is a single-wire LIN transceiver 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 automotive microcontrollers and the LIN bus, 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 node control in body electronics modules such as door locks and seat positioners.

For engineers reviewing the TLE72593GEXUMA3 datasheet, TLE72593GEXUMA3 pinout, TLE72593GEXUMA3 application, or TLE72593GEXUMA3 equivalent, key selection criteria include sleep-mode current (<8 µA), BUS short-to-VBAT/GND handling, INH-controlled external regulator enablement, and Flash mode support for MCU programming over LIN.

Technical Context

The TLE72593GEXUMA3 implements a Smart Power Technology (SPT®)-based analog front-end with dual-slope transmission control: Normal Slope mode (≤20 kbps) and Flash mode (accelerated MCU programming). Its receiver includes noise-filtering circuitry and delay symmetry optimization to meet stringent automotive EMI immunity requirements per ISO 11452 and CISPR 25.

Mode transitions are controlled exclusively via the EN pin, with deterministic behavior across Sleep, Stand-By, and Normal Operation modes. The INH output is battery-referenced (VS), enabling direct control of external LDOs or master termination resistors, while the WK pin provides edge-triggered local wake-up with internal pull-up.

Key Specifications

Parameter	Value and Actual Design Meaning
Sleep Current	<8 µA typical - enables always-on partial-network operation without draining vehicle battery
Bus Voltage Range	5.5 V to 27 V - supports both 12 V and 24 V automotive systems with undervoltage lockout
LIN Data Rate	2.4 kbps to 20 kbps - covers full LIN 2.x specification range including diagnostic and flash programming
ESD Robustness	±15 kV HBM per IEC61000-4-2 - eliminates need for external TVS diodes in most body domain layouts
Thermal Protection	Integrated overtemperature shutdown - prevents latch-up during sustained bus fault conditions
Logic Compatibility	3.3 V and 5 V CMOS/TTL - interoperable with legacy and modern automotive MCUs without level-shifting
Wake-Up Sources	BUS line activity or WK pin negative edge - allows flexible system-level power management architecture

Pinout & Package

Package: PG-DSO-8 (lead-free, RoHS-compliant, AEC-Q100 qualified).

Pin/Terminal	Circuit Role	Design Meaning
RxD	Receive data output	Active-low LIN bus signal feedback to MCU; requires external pull-up for wake-up indication
EN	Enable input	CMOS-compatible control pin with internal pull-down; HIGH enables Normal Operation mode
WK	Local wake-up input	Active-low, negative-edge triggered; internal pull-up enables direct connection to mechanical switch or sensor
TxD	Transmit data input	Drives LIN bus via internal driver stage; dominant time-out prevents bus lock-up during MCU hang
GND	Ground reference	Power and signal return path; separate from chassis ground to maintain noise isolation
BUS	Single-wire LIN bus interface	Bi-directional I/O with internal termination; handles short-to-VBAT/GND and ESD events
VS	Battery supply input	Direct connection to vehicle battery (5.5–27 V); powers all internal circuitry and INH output
INH	Inhibit output	Battery-referenced (VS) open-drain output; controls external voltage regulators or master termination

Key Features

Feature	Design Value
Dual-slope transmission control	Normal Slope (EMC-optimized) and Flash mode (fast slew for programming) selectable via EN sequencing
Integrated bus termination	30 kΩ typical termination enabled in Normal/Stand-By modes - eliminates external resistor for slave nodes
Low-leakage BUS pin	<100 nA leakage - critical for partial-network wake-up integrity and battery-off current budgeting
Master node support	INH output drives external 1 kΩ + reverse diode termination - enables single-chip master implementation
Automotive-grade protection	Overtemperature shutdown, supply undervoltage detection, BUS short-circuit recovery - no external supervision required

Applications

Body Control Module (BCM)

Seat Position Memory System

Use Scenario: Centralized control of door locks, window lifts, and interior lighting via LIN subnetwork.

IC Role / Device Role / Timing Role: Physical layer transceiver interfacing MCU to LIN bus; manages sleep/wake transitions based on CAN wake or key-fob RF signal.

Use Value: Sub-8 µA sleep current extends battery life during vehicle off-state; INH output disables auxiliary power rails to meet OEM <100 µA total module quiescent requirement.

Use Scenario: LIN-connected seat ECU storing and recalling multiple user positions using non-volatile memory.

IC Role / Device Role / Timing Role: Bus interface with Flash mode support for in-vehicle reprogramming of seat calibration parameters.

Use Value: Flash mode's accelerated slew rate enables reliable firmware updates over LIN at >15 kbps, reducing service bay programming time by 40% vs standard slope.

Roof Module (Sunroof/Blind Control)

Climate Control Actuator

Use Scenario: Distributed sunroof and power blind control with position feedback and obstacle detection.

IC Role / Device Role / Timing Role: LIN transceiver with BUS short-to-VBAT protection - sustains operation during wiring harness abrasion faults common in roof channels.

Use Value: Integrated short-circuit handling avoids fuse blowing or MCU reset during intermittent shorts, improving field reliability and reducing warranty claims.

Use Scenario: HVAC blend door actuator communicating temperature setpoints and motor status over LIN.

IC Role / Device Role / Timing Role: Low-emission transceiver meeting CISPR 25 Class 5 radiated emissions limits in confined dashboard space.

Use Value: Optimized EMC performance eliminates need for ferrite beads or shielded cables, cutting BOM cost by $0.32/unit at 500k annual volume.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC33661ELR2	Higher sleep current (15 µA typ), no Flash mode, 5 V logic only	Lacks bus wake-up via BUS pin; requires external wake-up controller for partial-network operation	Prefer when cost sensitivity outweighs ultra-low sleep current and flash programming needs
ATA663211-TAQY	Integrated voltage regulator (5 V), higher ESD (±20 kV), but no INH output	Cannot directly control external LDOs or master termination; requires additional discrete components	Choose when system-level integration (regulator + transceiver) reduces PCB area more than INH functionality adds value

Compared with MC33661ELR2 and ATA663211-TAQY, the TLE72593GEXUMA3 uniquely combines sub-8 µA sleep current, Flash mode, and battery-referenced INH output-enabling single-chip master node design and certified partial-network compliance without added components.

FAQ

What LIN protocol versions does the TLE72593GEXUMA3 support?

The TLE72593GEXUMA3 complies 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 bus voltage levels, timing tolerances, and fault detection thresholds defined in those standards - verified through Infineon's AEC-Q100 stress testing and third-party LIN conformance labs.

How does the Flash mode differ from Normal Slope mode electrically?

Flash mode increases the BUS pin slew rate to reduce bit time uncertainty during high-speed programming sequences, enabling reliable communication at >15 kbps. Normal Slope mode uses a slower, EMC-optimized slew rate for standard data transmission (≤20 kbps) to minimize radiated emissions. Mode switching occurs only via EN pin state changes and is internally synchronized to avoid bus glitches.

Can the TLE72593GEXUMA3 be used as a LIN master without external components?

Yes - when configured as a master node, the INH output drives an external 1 kΩ resistor and reverse diode connected between BUS and VS (or INH), providing active pull-up termination. No additional transistors or controllers are needed, satisfying LIN master electrical requirements per ISO 17987-4 Annex C.

What is the maximum allowable capacitive load on the BUS pin?

The BUS pin is characterized for up to 1000 pF total line capacitance, including cable, connectors, and stubs. This supports daisy-chained topologies with up to 16 nodes over 20 m of twisted-pair wiring at 19.2 kbps, as validated in Infineon's application note AN260 and EMC test reports per ISO 11452-4.
