TLE7258DXUMA1

The TLE7258DXUMA1 is an automotive-grade LIN (Local Interconnect Network) transceiver from Infineon. It provides a robust interface between a microcontroller and a LIN bus, handling bus signaling, wake-up, and fault protection in one device.
Key points:
- Function: Drives and receives the LIN bus while protecting the MCU from automotive transients; supports LIN 2.x protocols.
- Protection and safety: includes undervoltage/overvoltage protection, short-to-GND or short-to-BAT protection, overtemperature protection, and fault diagnostics.
- Modes: supports sleep/standby and wake-up behaviors to minimize current consumption in idle conditions.
- Environment: designed for automotive use with wide voltage ranges and extended temperature range; available in an automotive packaging variant (DXUMA1).
- Applications: body electronics, door modules, lighting, seat controllers, and other LIN-based subsystems.
- Notes: Always consult the latest datasheet for exact voltage ranges, pinout, timing, and electrical characteristics for your design.

- Reverse polarity protection
- Soft-start to limit inrush current
- Diagnostic feedback: fault/status flags (e.g., open-load, short to GND, overcurrent)
- Enable control with PWM capability for on/off switching
- Multi-channel/high-side switch architecture with minimal external components
- Low quiescent current in standby
Note: Please verify exact channel count and package details from the datasheet for your specific application.

Eight pins. It’s an automotive LIN transceiver (TLE7258) in the DXUMA1 package, providing a bidirectional interface between a microcontroller and the LIN bus on 12 V networks, with MCU TXD/RXD signals, the LIN bus pin, Vcc and GND, and integrated wake-up and protection features.

- Manufacturer: Infineon Technologies AG.
- What kind of company: A German multinational semiconductor manufacturer and supplier of system solutions for automotive, industrial power, and security markets.

TLE7258DXUMA1 is used mainly in automotive 12V body electronics as a smart load switch. Typical application areas:
- Automotive: load switching for lamps, motors, solenoids, pumps, wipers, power seats, window regulators, HVAC actuators, and other DC loads.
- Power distribution with protection/diagnostics: short-circuit (to ground/battery), overcurrent, undervoltage, overtemperature protection and fault/status reporting to the ECU.
- Industrial/DC motor or actuator control in harsh environments.
In short, it enables protected, diagnosable DC load switching in vehicle and similar applications.

The TLE7258DXUMA1 comes in a 16‑pin PowerSSO package (PG‑DSO‑16), i.e., a 16‑pin power package.
