Page 2: Introduction
The board is available in different variations of the Smart High-Side Power Switch, depending on which of Infineon's products the user wants to employ. Each one is built by a vertical N-channel power MOSFET with charge pump. Due to the integrated charge pump the channels can be controlled by standard digital IOs (3.3 V and 5 V supported). -

Page 13: Diagnosis And Sense (Den And Is)
™ PROFET +2 12V Arduino Shield 2 Board description The limits of the pull-up current reflect the maximum allowed load current, which does not activate the load. That depends strongly on the load, and has to be adapted accordingly. As leakage currents battery-to-output (for example, output leakage current IL(OFF)) and output-to-GND may occur in a system, resistors for pull-up and pull-down may be needed. - Page 14 ™ PROFET +2 12V Arduino Shield 2 Board description Figure 8 Diagnosis and Sense (DENx and ISx) User Manual Rev. 1.00 2019-10-23...
