EZ-PD™ ACG1F One-Port USB-C Controller

Overview

One port USB-C controller with integrated VBUS load switch

EZ-PD™ ACG1F (Type-A to Type-C Generation - 1 FET) is a single-port USB-C controller that complies with the latest USB Type-C specifications. It provides a complete USB-C control solution for notebooks and desktops. EZ-PD™ ACG1F is used in systems that need to convert legacy Type-A data ports to Type-C data ports. It uses Infineon's proprietary M0S8 technology with a 16-bit Flash, 32-bit ARM® Cortex®-M0 processor and integrates a Type-C controller (without Power Delivery) and a VBUS load switch (5 V / 3 A).

EZ-PD™ ACG1F supports Downstream Facing Port (DFP) only.
