Diodes Incorporated AP33772 USB Type-C™ PD Sink Controller meets USB Power Delivery specification Rev. 3.0 v1.2. Because of its high voltage process, the AP33772 provides a cost-effective USB PD solution without the need for external discrete high-voltage components like LDOs. During the protocol handshake process, packets are transmitted and received through a Biphase Mark Coding (BMC) transceiver with a good eye diagram and high noise immunity. The AP33772 supports I2C communication to implement all of the PD sink functions, such as the requesting of power profiles, Power Device Objects (PDO), and Augmented Power Device Objects (APDO). Rich power functions embedded on the chip reduce the total bill of materials (BOM) while maintaining maximum flexibility.
The AP33772 features on-chip OTP/MTP memory which is used to store main protocol decoding and application programs as well as system configuration parameters. The device also includes an integrated multiple-channel Analog-to-Digital Converter (ADC) which can be used to sense internal and outside signal variations to support various system status updates and controls accordingly.
The Diodes Incorporated AP33772 USB Type-C PD Sink Controller is available in a W-QFN4040-24 package ideal for space-constrained applications.
