CY2569
USB PD Sink Controller
Description
The CY2569, a highly integrated USB Type-C PD3.0/PPS sink controller, is targeted for DC power request and control for a Type-C Connector equipped Devices (TCD). To leveraging increasing popularity of standard Type-C PD3.0 power adaptors, the CY2569 negotiates with an existing PD3.0 adaptor to acquire the required power profile to supply the TCD.
Working its role as DC-Power request from a USB PD source, the CY2569 interprets power input requirements (voltage/current and maximum power) from the TCD, and then establishes power link through configuration channel (CC) communication with an external USB PD3.0 adaptor to output a suitable DC power for TCD device. The voltage requests could be easily specified by 3 pins (VSEL2, VSEL1, VSEL0), up to 8 voltages can be selected and both fixed PDO (Power Data Object) and PPS APDO (Augmented Power Data Object) in PD source adapter are supported in CY2569 search algorithm. Also, up to 10 maximum power levels can be selected through different resistance value of the resistor connected to pin PSEL (refer to figure 1 and 2).
There are rich power functions embedded as hardware or enabled by built-in firmware in the chip so as to reduce total BOM while maintain maximum flexibility. A one-time–programming (OTP) ROM is provided to store the PD/Sink controller firmware.
