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 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.
