Infineon TLE8457DSJXUMA1, 1 Line Transceiver

The Infineon TLE8457DSJXUMA1 is a high-reliability LIN transceiver with a built-in low-dropout (LDO) voltage regulator, designed for robust in-vehicle communication and control systems across the UK. This compact PG-DSO-8 packaged device supplies up to 70 mA to a microcontroller, supports ISO 17987-4 and SAE J2602 LIN communication (up to 20 kbit/s), and operates with ultra-low standby consumption (~20 µA). Built to automotive standards and harsh UK conditions (–40 °C to +150 °C), it simplifies design, reduces component count, and ensures efficient, resilient operation in high-demand embedded systems.

Why Invest in the Infineon 1 Line Transceiver?

The TLE8457DSJXUMA1 offers a blend of communication and power delivery. Its integrated LDO regulator reduces component count and board area, while ultra-low quiescent current suits battery-powered or idling applications. With LIN link robustness (bus short, over- and under-voltage, temperature protection) and VIN reset monitoring, it ensures maximum reliability, making it an ideal choice for UK engineers designing resilient automotive or industrial embedded systems.
