The AP33771 is a highly integrated USB Type-C® PD3.0/PPS sink controller. The device is targeted for DC power requests and control for Type-C connector-equipped devices (TCD). To leverage increasing popularity of standard Type-C PD3.0 power adaptors, the AP33771 negotiates with an existing PD3.0 adaptor to acquire the required power profile to supply the TCD.
Working its role as DC-power requests from USB PD sources, the AP33771 interprets power input requirements (voltage/current and maximum power) from the TCD, and then establishes a power link with an external USB PD3.0 adaptor to output a suitable DC power. The voltage requests are specified by three pins (VSEL2, VSEL1, VSEL0). Up to eight voltages can be selected, and both fixed PDO and PPS APDO in the PD source adapter are supported in the AP33771 search algorithm. Up to ten maximum power levels can also be selected through different resistance values of the resistor connected to the PSEL pin (refer to figure 1 and 2).
Rich power functions are embedded on the chip to reduce total BOM while maintaining maximum flexibility. A one-time-programmable (OTP) ROM is provided to store the PD/sink controller firmware.
