The DIODES™ AP33772 is a highly integrated USB Type-C® PD3.0/PPS sink controller targeted for DC power request and control for USB Type-C connector-equipped devices (TCD). To leverage the increasing popularity of standard USB Type-C PD3.0 power adaptors, the AP33772 negotiates with an existing PD3.0 adaptor to acquire the required power profile to power the TCD.
For more flexible PD3.0 and PPS power applications where direct voltage and current request with fine-tuning capabilities (20mV/Step, 50mA/Step) are required, the AP33772 supports I2C communication – I2C Interface pins (SCL, SDA), I2C registers and command setting, for host CPU of TCD to communicate with.
Rich power functions embedded on the chip reduce total bill of materials (BOM) while maintaining maximum flexibility. A one-time-programmable (OTP) ROM is provided for the main firmware and a multi-time-programmable (MTP) ROM will be provided for user-configuration purpose.
