WT61F201

WT61F201 is a dual-port USB/PD Controller with 128KB embedded Flash and 4KB SRAM, which is compliant with USB Power Delivery 3.1 supporting all standard power profiles. It provides the USB PD communication for two USB-C ports and one USB Billboard Device Class for USB-C applications. Also, USB-C Charging Upstream-facing Port (UFP), Dual Role Power (DRP) with Fast Role Swap (FRS), DP Alt-mode Configuration, USB Billboard Device and In-System-Programming (ISP) through USB-C are supported.With rich functions in one chip, the WT61F201 is suitable for applications such as video adapters, multi-function docking stations, dongles, power banks, and monitors.
