TLE75008ESDXUMA1

Product Overview

The TLE75008ESDXUMA1 from Infineon Technologies is a low-side N-channel power switch/driver with eight outputs in a 1:8 configuration. It is controlled through SPI and is suitable for relay and solenoid load switching. The load voltage range is 3V to 28V, and the supply voltage range is 3V to 5.5V. Each output is rated for 330 mA maximum current, with a typical 1 Ohm on-resistance. The device provides slew rate control and fault protection including fixed current limiting, open load detection, over-temperature protection, and over-voltage protection. It operates from -40°C to 150°C junction temperature and is automotive grade with AEC-Q100 qualification. The surface mount package is PG-TSDSO-24-51.

Design & Procurement Notes

Confirm each load is within 330 mA and 3V to 28V. Account for 1 Ohm on-resistance losses and thermal layout using the exposed pad. Ensure the controller supports SPI and review fault responses for current limiting, open load, over temperature, and over voltage. The AEC-Q100 automotive grade is relevant for qualified vehicle applications.
