Intended for use in a range of USB PD products employing direct current (DC) power including AC adapters, PCs, smartphones, other consumer and office equipment, and toys, Renesas Electronics has announced its new R9J02G012 USB Power Delivery (USB PD) controller. According to Renesas, the R9J02G012 is the industry’s first single package solution that supports both USB Power Delivery Rev. 3.0 (USB PD 3.0) and USB Type-C Authentication Rev 1.0, which enables device-to-device authentication.
The demand for fast charging mobile devices is growing, driving increased demand for high DC power delivery (e.g. 100W). Previously, system manufacturers frequently implemented proprietary fast-charging methods using USB Micro-B connectors. However, with recent smartphone charging/battery incidents, it is critical to offer a safe ecosystem of USB PD compatible products. The USB Implementers Forum (USB-IF), a technology consortium, has standardised the following specifications to provide open, unified and interoperable technologies to fulfill these market needs:
As a long-time supporting member and a board member for USB Implementers Forum, Renesas has adopted all three standards. The new R9J02G012 is a flexible, small-package USB PD controller for USB Type-C port control on any USB PD devices. All connecting ports to these USB PD devices with the R9J02G012 will be able to electronically verify and trust its authenticity based on the certificates and public key infrastructure (PKI) defined in the USB Type-C Authentication specification. This mechanism allows system manufacturers to implement policies to examine the genuine origin of the connected PD devices such as cables and chargers before a high-power charging of (e.g., 20V at 3A) is executed.
