Description
The TLE7251VLEXUMA1 is Infineon’s single‑channel automotive LIN transceiver. It sits between an MCU LIN controller and the LIN bus, providing the necessary level shifting and bus protection to run LIN networks in vehicles.
Key points:
- Purpose: LIN bus interface for automotive microcontrollers (body electronics, sensors, actuators, etc.).
- Protection and robustness: over/undervoltage, overcurrent, thermal shutdown, load-dump/transient protection, and ESD tolerance typical of automotive devices.
- Features: wake-up/bus-dominant signaling, low sleep current, suitable for 12V automotive environments.
- Package: available in Infineon’s compact UMA/LEX UMA1 style package variant for space-constrained designs.
Note: This is a high-level intro. For exact electrical specifications, pinout, voltage ranges, timing, and recommended usage, consult the official TLE7251VLE datasheet and application notes.
