USBPD and Multiple Fast Charging Protocol Receiving Chip CH224 CH224K is a USB Power Delivery protocol controller integrated circuit designed for fast-charging and programmable USB Type-C power negotiation applications. The device enables intelligent voltage trigger and power profile selection from compatible USB Type-C and USB PD power sources, making it suitable for embedded power systems, portable electronics, development boards, and battery-powered devices. This controller supports automatic communication with USB Type-C power adapters to negotiate higher voltage and current profiles for efficient power delivery. It simplifies USB PD implementation by integrating protocol handling, voltage selection logic, and interface control into a compact low-power solution with minimal external component requirements. The CH224K is widely used in DIY electronics, portable charging systems, embedded controllers, IoT hardware, industrial devices, and USB Type-C powered applications requiring stable and configurable DC power input. Its compact surface-mount package and simplified design architecture enable rapid integration into space-constrained PCB layouts. #commonpartslibrary #usbtypec #usbpd #powerdelivery #powermanagement #embeddedhardware #fastcharging #electronicscomponents #portableelectronics #surfacemountdevice

The HUSB238A is a highly integratedstand-aloneUSB Type-C® and Power Delivery (PD) Sinkcontroller.The HUSB238A integrates the CClogic, USBPDprotocol and the legacy protocols. The HUSB238A can run in I2C mode andGPIOmode.In I2C mode, an I2C master can access theHUSB238Ato configure settings, read back status andperformadvanced functions such as DRSwap, VDMmessages. The HUSB238A supports APDO, maximum48 V/5 A EPR FPDO and EPR AVSin I2Cmode. While in GPIO mode, the configuration is achievedviathe setting pins. The HUSB238A can beconfiguredtosupport maximum 28 V/3.25 A PDOviaVSETandISET pins, only two resistors are usedtoset thevoltage and current. The ultra-low operation current of theHUSB238Ahelps the system to reduce the total power dissipationand suitable for a battery application. The HUSB238A is available in QFN3 mmx3mm-16Lpackage.
