Digital and mixed-signal IP and ASIC RISC-V reference design for USB Type-C/PD power adapter/charger

All Silicon IP


IQonIC Works USB-C/PD power adapter IP includes components required to build an integrated programmable power supply (PPS) charger solution.

The USB Type-C source controller detects connections and controls provision of VBUS and VCONN power.

The USB BC and QuickCharge controller negotiates power supply for legacy devices using BC1.2 and QC2/3/4 protocols.

The USB PD controller autonomously negotiates power contracts with a device using PD 2.0 or 3.0 protocols, including PPS messaging. It includes PHY, protocol, and source policy layers, and integrates with a host processor that provides device policy management.

The usb_pa_platform reference design integrates these IP blocks with other IQonIC Works IP into a complete power adapter ASIC solution. The platform includes power-supply control using an IDAC, VBUS load switch control, ADC, fault monitoring, temperature sensing, a RISC-V processor subsystem with ROM/OTP/SRAM memory, and I2C and GPIO interfaces.

IQonIC Works provides embedded firmware for the usb_pa_platform. The firmware can be customized for a target application using IQonIC Works IDE, which integrates with the embedded debugger in the hardware platform.
