Product details
Overview
TLE7269GXUMA3 from Infineon is a dual-channel automotive LIN transceiver in PG-DSO-14 package, compliant with LIN 1.3/2.0/2.1 and SAE J2602 standards, supporting up to 20 kBaud data rate, ±8 kV ESD robustness (IEC61000-4-2), and dual independent sleep-mode wake-up via BUS1/BUS2 or local WK pin - deployed in body control modules for distributed door/window node communication.
For engineers reviewing the TLE7269GXUMA3 datasheet, TLE7269GXUMA3 pinout, TLE7269GXUMA3 application, or TLE7269GXUMA3 equivalent, key selection criteria include dual-transceiver independence, bus short-to-GND handling, INH-controlled external voltage regulator support, low-slope/flash mode configurability, and AEC-Q100 qualification for under-hood environments.
Technical Context
The TLE7269GXUMA3 integrates two fully independent LIN physical layer transceivers on a single Smart Power Technology (SPT®) die, each with dedicated INH outputs, separate TxD/RxD paths, and configurable wake-up sources (bus or local WK). It implements three slope modes - Normal, Low Slope, and Flash - to balance EME reduction and signal integrity across varying cable lengths and network loads.
Each transceiver supports autonomous operation: BUS2 wake-up can be disabled via W2O pin; EN pin controls global mode transitions; VS-supplied INH1/INH2 drive external regulators or master termination resistors; and internal receiver filters suppress common-mode noise while maintaining >15 kV/m EMI immunity per ISO 11452-4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VS) | 5.5 V to 27 V - enables direct battery connection without pre-regulation in 12 V automotive systems. |
| Data Rate | Up to 20 kBaud - meets full LIN specification range (2.4–20 kBaud), supporting both legacy and high-speed diagnostics. |
| Sleep Current | <10 µA per channel - sustains ultra-low quiescent power in parked vehicle state with dual wake-up capability. |
| ESD Robustness | ±8 kV HBM - eliminates need for external TVS diodes on BUS1/BUS2 lines in most OEM architectures. |
| Bus Short Protection | Detects and survives short-to-GND and short-to-VBAT - prevents latch-up during wiring faults in harness assemblies. |
| Logic Compatibility | 3.3 V or 5 V VIO - interfaces directly with mixed-voltage microcontrollers without level-shifting circuitry. |
| Thermal Shutdown | Activates at Tj > 160 °C - protects against thermal runaway during sustained overcurrent or ambient extremes. |
Pinout & Package
Package: PG-DSO-14 (Green, RoHS-compliant, 150 mil wide body, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RxD1 | Receive output channel 1 | Active-low dominant indicator; floats during Sleep; driven low after BUS1 or WK wake event. |
| 2 EN | Global enable input | Pull-down enabled; HIGH forces Normal/Standby; LOW enables Sleep mode with wake detection active. |
| 3 WK | Local wake-up trigger | Negative-edge sensitive; internal pull-up; initiates wake from Sleep for both transceivers. |
| 4 TxD1 | Transmit input channel 1 | Pull-down enabled; LOW drives BUS1 dominant; weak pull-down (350 kΩ) after bus wake, strong (>1.5 mA) after WK wake. |
| 5 TxD2 | Transmit input channel 2 | Identical behavior to TxD1 but independent; no cross-coupling between channels. |
| 6 VIO | I/O voltage reference | Accepts 3.3 V or 5 V supply; sets logic threshold for all RxD/TxD pins; decoupled from VS. |
| 7 RxD2 | Receive output channel 2 | Same timing and drive behavior as RxD1; independent wake detection on BUS2 only. |
| 8 INH2 | Inhibit output channel 2 | Voltage-rail referenced (VS); HIGH in Normal/Standby; controls external regulator or master termination on BUS2. |
| 9 W2O | BUS2 wake-off control | Active-HIGH; disables BUS2 wake detection while preserving BUS1 wake functionality. |
| 10 BUS2 | Physical LIN bus interface 2 | Bidirectional; internal pull-up and termination; short-to-GND tolerant; recessive = VS, dominant = GND. |
| 11 GND | Power ground | Analog/digital common reference; tied to exposed thermal pad for thermal conduction. |
| 12 BUS1 | Physical LIN bus interface 1 | Identical electrical behavior to BUS2; independent fault handling and wake detection. |
| 13 VS | Battery supply input | 5.5–27 V range; powers internal regulators, drivers, and protection circuits; includes UVLO at ~5.0 V. |
| 14 INH1 | Inhibit output channel 1 | VS-referenced; synchronous with INH2 but independently controllable; used for BUS1 master termination. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LIN transceivers | Enables two isolated LIN subnets (e.g., front/rear door modules) on one IC, reducing BOM count and PCB area by 40% vs. dual discrete solutions. |
| Configurable slew-rate modes | Normal, Low-Slope, and Flash modes allow EME optimization per node location-Low-Slope for long cables, Flash for fast diagnostics. |
| Bus short-to-GND recovery | Automatically recovers from sustained short-to-GND faults without reset or intervention-critical for field-repairable harness designs. |
| Separate INH outputs per channel | Allows independent control of external 5 V/3.3 V regulators for MCU and peripheral ICs, enabling selective power gating per LIN subnet. |
| WK-triggered wake with BUS2 disable | W2O pin lets designers retain local wake capability while disabling BUS2 wake to prevent false triggers in noisy rear-harness zones. |
Applications
| Body Control Module (BCM) | Roof Module (Sunroof/Interior Light) |
|---|---|
|
Use Scenario: Centralized control unit managing door locks, window lifts, and mirror actuators across four doors using two daisy-chained LIN subnets. IC Role / Device Role / Timing Role: Dual-transceiver physical layer interface; each channel handles one pair of doors (front/rear), with independent INH-driven power domains. Use Value: Reduces component count by replacing two TLE7259-3GE units; enables synchronized wake-up across all nodes via single WK line. |
Use Scenario: Roof-mounted module integrating sunroof motor, interior ambient lighting, and rain sensor signals into a single LIN node. IC Role / Device Role / Timing Role: Single-chip dual-LIN interface: BUS1 connects to BCM master; BUS2 links to distributed LED driver nodes with low-slope mode for EME-sensitive cabin zone. Use Value: Eliminates need for external bus termination resistors on BUS2; W2O disables BUS2 wake during vehicle sleep to avoid false triggers from parasitic leakage. |
| Seat Control Unit | Trunk/Liftgate Module |
|
Use Scenario: Driver-seat ECU controlling lumbar, heating, and position memory functions via LIN slave nodes (motor drivers, sensors). IC Role / Device Role / Timing Role: Transceiver 1 serves as master node driving seat motor LIN bus; transceiver 2 acts as slave interface to climate control LIN subnet. Use Value: Flash mode enables rapid firmware updates over LIN; INH1 powers seat MCU while INH2 supplies heater driver IC - enabling independent thermal management. |
Use Scenario: Liftgate actuator module communicating position feedback, obstruction detection, and anti-pinch status to BCM over LIN. IC Role / Device Role / Timing Role: BUS1 handles primary command/response traffic with BCM; BUS2 connects to auxiliary sensors (water ingress, latch status) with bus short-to-GND tolerance. Use Value: Survives harness shorts during assembly or service; low-leakage BUS pins (<100 nA) prevent battery drain when liftgate is detached for repair. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1028TK/0Z | Single-channel LIN transceiver; requires two units for dual-bus implementation; lacks integrated W2O and separate INH per channel. | Higher PCB footprint and BOM cost; no native BUS2 wake-disable function; external logic needed for independent regulator control. | Select when existing design uses NXP ecosystem and dual discrete layout is already validated. |
| ST TLE7259-3GE | Single-channel pin-compatible device; identical pinout per channel but no dual integration; no W2O or dual INH outputs. | Requires duplicated routing and passive components; cannot achieve same level of subsystem-level power gating or wake isolation. | Choose for incremental upgrade from legacy single-transceiver designs where space constraints permit duplication. |
Compared with TJA1028TK/0Z and TLE7259-3GE, the TLE7269GXUMA3 delivers true hardware-level dual-channel autonomy - reducing interconnect complexity, eliminating duplicate passives, and enabling precise per-bus power/wake control unattainable with discrete or single-channel alternatives.

FAQ
What LIN protocol versions does the TLE7269GXUMA3 support?
The TLE7269GXUMA3 is compliant with LIN specifications 1.3, 2.0, 2.1, and SAE J2602. It supports all mandatory frame formats, checksum models (classic and enhanced), and diagnostic services defined in these standards - including auto-baud detection and error frame generation - without firmware modification.
Can BUS1 and BUS2 operate at different data rates simultaneously?
No - both transceivers share the same internal clock domain and slope control logic, so they must operate at identical baud rates and slope modes. However, their enable states, wake sources, and INH outputs are fully independent, allowing asynchronous entry/exit from Sleep or Standby.
How does the W2O pin affect wake-up behavior?
When W2O is driven HIGH, BUS2 wake-up detection is disabled - meaning only BUS1 traffic or the local WK pin can wake the device from Sleep. RxD2 remains functional in Normal mode, but its wake comparator is gated off, preventing false triggers from noisy rear-harness segments.
Is external termination required for master-node configuration?
Yes - for master-node operation, a 1 kΩ resistor plus reverse-biased diode must be connected between BUS1 (or BUS2) and VS (or INH1/INH2) to provide the master pull-up. The TLE7269GXUMA3 provides internal termination only for slave nodes; master termination is external and configurable per bus.
