OC01 - High Current DC Switch

Product highlights

• 6 A Switching Current Capable
• Fast Switching
• 4 High Current Output Channels
• Output LEDs

Overview

This xCHIP forms part of the interface modules and is equipped with a high speed IO expander chip allowing the user to switch a high current through the available MOSFETs. The module is based off the PCA9536 remote 4-bit I²C I/O expander and 4 DMN2041L 6.4 A MOSFETs to provide 4 channels. Each channels is equipped with an output indicator LED to allow for easy debugging.
