TLE92464ED EVALBOARD

Overview

TLE92464ED evaluation board provides a quick pick and place solution for costumer’s lab evaluations.

The Evaluation board comes with the Solenoid Driver TLE92464ED and all required external components. The Evaluation PCB is designed on an Arduino Formfactor which makes it controlled by all Arduino compatible microcontroller boards, e.g.: Infineon XMC1100 Boot Kit, Infineon XMC4700 Relax Kit, Aurix ShieldBuddy or Arduino Uno. Please note that the microcontroller board is not included.
