Product details
Overview
TLE7268SKXUMA1 from Infineon Technologies is a dual-channel automotive LIN 2.2 / SAE J2602 transceiver in PG-DSO-14 package, providing two independent single-wire bus interfaces with up to 20 kbps data rate, integrated wake-up capability on either bus, and <10 µA sleep current. It serves as the physical layer interface between microcontrollers and LIN networks in body control modules and gateways.
For engineers reviewing the TLE7268SKXUMA1 datasheet, TLE7268SKXUMA1 pinout, TLE7268SKXUMA1 application, or TLE7268SKXUMA1 equivalent, key selection criteria include dual-channel LIN compliance (ISO 17987-4), bus short-to-battery/GND protection, dominant time-out safety, INH-controlled external regulator enable, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7268SKXUMA1 implements two fully independent LIN transceivers sharing only supply (VS) and ground (GND), each with dedicated ENx, TxDx, RxDx, and BUSx pins. Each channel supports Normal Operation, Standby, and Sleep modes with autonomous wake-up detection via bus activity or EN pin assertion.
It integrates LIN slave termination on both BUS1 and BUS2 pins, RF-filtered receivers with noise suppression, slew-rate controlled transmitters for EME reduction, and fail-safe functions including overtemperature shutdown, undervoltage lockout, TxD time-out, and short-circuit protection on BUSx pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN2028QDRBRQ1 | TI dual LIN transceiver with 1 Mbps CAN FD coexistence support; no integrated BUS termination | Targeted at mixed LIN/CAN FD gateways requiring shared routing; higher cost and complexity | Select when CAN FD co-location or higher-speed diagnostics are required; adds external termination and layout constraints |
| TLE7259-3GE | Infineon single-channel LIN transceiver in PG-DSO-8; identical pinout compatibility but half channel count | Used where only one LIN subnet is needed or space-constrained designs require smaller footprint | Select for cost-sensitive single-LIN applications; requires two units for dual-channel functionality |
Compared with TLIN2028QDRBRQ1 and TLE7259-3GE, the TLE7268SKXUMA1 uniquely delivers dual-channel integration with embedded slave termination and sub-10 µA sleep current - optimizing BOM, layout, and power in compact automotive ECUs.

FAQ
What LIN protocol versions does the TLE7268SKXUMA1 support?
The TLE7268SKXUMA1 complies with LIN Specification 2.2A, ISO 17987-4 (LIN Physical Layer), and SAE J2602. It supports all mandatory timing parameters and frame formats defined in these standards, including auto-synchronization, checksum types, and error detection mechanisms - verified per official Infineon test reports.
Does the device require external termination resistors on BUS1 and BUS2?
No. The TLE7268SKXUMA1 integrates LIN slave termination resistors on both BUS1 and BUS2 pins, eliminating the need for external 1 kΩ resistors. This reduces bill-of-materials cost and PCB real estate while maintaining compliance with LIN physical layer specifications for slave node implementation.
How does the INH output behave during Sleep mode?
The INH output goes low (open-drain inactive) when both transceivers are in Sleep mode. It transitions high only when either transceiver enters Normal Operation or Standby mode - enabling precise control of external voltage regulators and ensuring zero-load current draw during deep sleep states.
Can TLE7268SKXUMA1 be used in master node configurations?
Yes, but requires external components: a 1 kΩ pull-up resistor and diode between BUSx and VS to implement master termination. The device itself provides only slave termination; master node functionality is achieved via this external network, as specified in Infineon Application Note AN478.
