This OT9121 is an easy to integrate and configure Type-C sink port with Power Delivery. It is delivered as RTL and an Analog Front End hard macro. No processor, software, or external memory is required. Re-uses much of Obsidian’s mature and widely used Type-C logic and analog IP. The IP controls the power supply directly. An external IP is available for clock generation which does not require chip pins. Also a voltage and current reference IP for use when this is not available. Standard current and voltage PDOs are supported, but may be altered with a serial port.
