TLE7258DXUMA1

The TLE7258DXUMA1 is an automotive smart high‑side switch from Texas Instruments. It combines a power MOSFET, drive logic, and protection features in a single package to switch a load on the supply side under MCU control. Designed for 12V automotive networks, it handles transients and provides built-in protections and diagnostics to simplify safety‑critical designs.
Key points:
- One-channel high‑side switch with a low‑current control input.
- Protections: reverse polarity, overcurrent/short‑circuit, overtemperature, undervoltage lockout.
- Diagnostic capability to report fault conditions to the microcontroller.
- Aids reliability and safety by reducing external discrete components.
- Suitable for driving loads such as lights, pumps, fans, and actuators in automotive body and powertrain applications.
- Automotive‑grade device (AEC‑Q100 qualified) in an UMA packaging variant.
In short, it lets you switch a load safely from a microcontroller with built‑in protection and fault reporting, simplifying automotive power electronics design.

8-pin HVSON (High-Voltage Small Outline) package.

Pin count: 8 pins.
Function: TLE7258DXUMA1 is an 8‑pin LIN transceiver (UMA package) that provides the physical layer interface between a microcontroller and a LIN bus. It uses MCU TXD/RXD signals on the control side and LIN on the bus side, with VCC and GND power pins plus one or more control/diagnostic pins (e.g., enable/wake) and integrated protections (short‑to‑VBATT/ground, undervoltage, ESD).

- Manufacturer: Infineon Technologies AG.
- What kind of company: A German multinational semiconductor company that designs, manufactures, and markets microelectronics and semiconductor solutions for automotive, industrial, and security applications.

Automotive 12V systems: power distribution and load switching for ECUs, sensors and actuators; built-in protection and diagnostics (short‑circuit, reverse polarity, overtemperature); suitable for infotainment, lighting, body electronics, and industrial 12V applications requiring robust protection and fault reporting.

There isn’t a single exact drop-in cross for TLE7258DXUMA1; a direct equivalent depends on required features (supply range, wake-up, data rate, filtering, package). Typical substitutes from other vendors include NXP TJA1020/TJA1021 LIN transceivers and Microchip MCP2003/MCP2004 LIN transceivers. For an accurate match, use Infineon’s cross-reference tool with your exact specs (package D/XUMA1, voltage, wake-up, etc.).
