R9A02G011 - USB PD 3.1 Controller, Type-C PMIC | Renesas
The Renesas R9A02G011 is a USB Power Delivery (PD) controller implementing the Universal Serial Bus Power Delivery Specification Revision 3.1 and USB Type-C Cable and Connector Specification Release 2.1, supporting USB PD 3.2 features including Programmable Power Supply (PPS) and Adjustable Voltage Supply (AVS). The device is available in a 32-pin HVQFN (5x5 mm) package or a 42-ball VBGA (3.6x3.1 mm) package, providing flexibility for space-constrained consumer electronics designs such as wall adapters, travel chargers, hub/downstream-facing ports (DFPs), and Type-C alternate-mode hosts.
A USB PD controller is a protocol-handling IC that negotiates higher voltage and current contracts (up to 100 W with Extended Power Range, EPR) over the USB Type-C VBUS conductor using BMC-encoded communication on the CC (Configuration Channel) lines. The R9A02G011 sits between the application host MCU and the USB-C connector, translating hardware-level USB-C attach/detach and PD messaging into I2C / GPIO interactions with the system, while controlling external VBUS FETs, VCONN switch, and discrete protection circuitry for safe power negotiation.
Key features include integrated USB Type-C Alternate Mode support for DisplayPort and Thunderbolt tunneling, Electronically Marked Cable (eMarker) read/write capability, BC 1.2 legacy charging support, integrated VBUS discharge and cable compensation, hardware autonomous PD state machine for minimal host MCU firmware load, and built-in protections including OVP, OCP, and thermal shutdown. The device requires an external host MCU for policy management and alternate-mode switching decisions.
Architecturally, the R9A02G011 implements a hardware CC logic block, a PD protocol engine, an integrated PHY for BMC transmission on CC1/CC2, and policy routing through an I2C slave interface. This partition lets the system MCU focus on application logic while the controller handles real-time PD timing, attach detection, and physical-layer compliance.
Typical applications include USB-C wall chargers, multi-port charging hubs, notebook and tablet docking stations, smartphone fast-charge adapters, and any Type-C source/sink/DRP port requiring USB PD 3.1 compliance. The wide protocol support makes it suitable for both consumer adapters and industrial docking equipment.
When designing with this part, ensure proper VBUS FET sizing for the highest advertised current (e.g. 5 A for 100 W EPR), a 1 uF CC-line bypass per USB Type-C spec, and consult the Renesas Rtk-251-drpevb evaluation board schematic for reference VBUS path protection.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including cross-references against competing USB PD controllers and recommendations for evaluation hardware.
