EZ-PD™ ACG1F One-Port USB Type-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 Type-C controller that complies with the latest USB Type-C specifications. ACG1F provides a complete USB Type-C control solution for notebooks and desktops. It is used in systems which need to convert legacy Type-A data port to Type-C data port. ACG1F 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).

ACG1F supports Downstream Facing Port (DFP) only.
