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.
