USB Type-C/PD Controller Enables 3A Current Delivery

FTDI Chip’s FT4233H is an advanced bridge IC with USB Type-C connectivity and USB power delivery that goes beyond powering consumer products and supports the higher current levels required by larger equipment. The FT4233H supports applications up to 100W and currents up to 3A. All the negotiation and power gauging activities are taken care of directly via the IC’s integrated 32-bit PD Policy Engine and USB Protocol Engine elements. No USB specific firmware programming is required. This means the system microcontroller does not have to get involved in such functions and system performance is not impacted.


Supporting USB High-Speed data rates (480 Mb/s), the USB bridge function is compatible with quad high-speed USB to multi-purpose bridging offered by the company’s previous generation FT4232H device. This includes UART, I2C, JTAG, Bit-Bang, or SPI via its integrated MPSSE Engine, on as many as four independently controllable channels. Support of two Type-C ports is encompassed, with a configurable port that can act as either a power sink or source (or in a dual role capacity) supporting Fast Role Swap, and the other port serving solely as a sink.
