Product Descriptions
The HUSB238A is a highly integrated stand-alone USB Type-C® and Power Delivery (PD) Sink controller. The HUSB238A integrates the CC logic, USB PD protocol and the legacy protocols. The HUSB238A can run in I2C mode and GPIO mode. In I2C mode, an I2C master can access the HUSB238A to configure settings, read back status and perform advanced functions such as DR Swap, VDM messages. The HUSB238A supports APDO, maximum 48V/5A EPR PDO and EPR AVS in I 2C mode. While in GPIO mode, the configuration is achieved via the setting pins. The HUSB238A can be configured to support maximum 28V/3.25A PDO via VSET and ISET pins, only two resistors are used to set the voltage and current. The ultra-low operation current of the HUSB238A helps the system to reduce the total power dissipation and suitable for a battery application. The HUSB238A is available in QFN 3 mm x 3 mm-16L package.
