The HUSB239 is a highly integrated stand-alone USB Type-C® and Power Delivery (PD) controller. The HUSB239 integrates the CC logic, USB PD protocol and the legacy protocols. The HUSB239 is freely to be configured by user as a Sink or DRP. Additionally, the debug accessories and audio accessories are both supported to be recognized.The HUSB239 can run in two modes I2C mode and GPIO mode. In I2C mode, an I2C master can access the HUSB239 to configure settings, read back status and perform advanced functions such as PR Swap, DR Swap, VDM messages. The HUSB239 supports PPS, SPR AVS, maximum 48 V / 5 A EPR PDO and EPR AVS in I2C mode.While in GPIO mode, the configuration is achieved via the setting pins. The HUSB239 can be configured to support maximum 28 V / 3.25 A PDO via VSET and ISET pins, only two resistors are used to set the voltage and current. And when HUSB239 acts as a source, the Rp can be configured via SRC_ISET pin. The ultra-low operation current of the HUSB239 helps the system to reduce the total power dissipation and suitable for a battery application. The HUSB239 is available in QFN 3 mm x 3 mm-16L package.
