It automates VBUS threshold detection as well as the various charging current levels, and includes an integrated VCONN power switch. The controller is programmable across multiple platforms through a fast mode I2C-bus interface.
The controller determines attachment through multiple comparators and a programmable 6‑bit digital-to-analog converter (DAC). The DAC determines the state of the VBUS and two configuration channel (CC) pins and relays information about attach/detach and charging current capabilities.
The controller is rated for a typical VDD supply voltage (VVDD) of 3.3V, with a typical VBUS supply voltage (VVBUS) of 5V (max. 21V).
The FUSB300C Programmable USB Type-C Controller is well suited for designers who want to create USB Type-C connections for smartphones, tablets, laptops, and wearables.
