GENERAL DESCRIPTION

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 I2C 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.
