Infineon TLE75080ESHXUMA1: 40 V Octal Low-Side Switch with SPI and Diagnostic Functions

Modern automotive and industrial systems demand robust, intelligent power switches capable of driving high-current loads while providing detailed system feedback. The Infineon TLE75080ESHXUMA1 addresses these needs as a highly integrated octal low-side switch, combining power control, communication, and comprehensive diagnostics in a single package.

This device is engineered to control eight independent channels, each capable of switching loads up to 40 V. Its integrated SPI interface serves as the communication backbone, allowing a host microcontroller to command each output individually, read back detailed diagnostic information, and configure key parameters like current limitation and slew rate. This digital control provides exceptional flexibility, enabling dynamic load management and system tuning.

A cornerstone of the TLE75080's value is its advanced diagnostic suite. It offers real-time feedback on each channel, including precise load current sensing and open-load detection in both on and off states. Crucially, it provides robust protection against overtemperature, overcurrent, and short circuits to ground or battery. In the event of a fault, the device can be configured to automatically shut down the affected channel and immediately flag the host controller via the SPI and a dedicated fault pin, ensuring system safety and enabling predictive maintenance.

Housed in a space-saving PG-DSO-36 package, the device is designed for harsh environments. Its 40 V operating voltage and strong ESD robustness make it ideal for 24 V automotive truck systems and industrial PLCs, where it commonly drives resistive, inductive, or capacitive loads such as valves, relays, and lamps.

ICGOOODFIND: The Infineon TLE75080ESHXUMA1 stands out as a superior solution for multi-channel power control, merging high-density switching, digital configurability, and extensive diagnostic capabilities to create smarter, safer, and more reliable electronic systems.
