GENERAL DESCRIPTION
HUSB251 is designed for a USB Type-C DRP product. It can support up to multiple PDOs with programmable voltage and current for different applications, such as PPS PDOs, EPR PDOs. All of PDOs are fully pliant with USB PD 3.1 Specification Rev.1.8
Besides, HUSB251 implements DPDM charging protocols for source. Both D+ and D- pins can be configured to support QC2.0, QC3.0, AFC, FCP, UFCS and divider 3 mode which provide excellent patibility for the legacy devices.
It integrates an GATE driver to enable between VBUS and VIN to protect the devices connected with Type-C connector.
The high voltage tolerance and protections at CC1, CC2, D+ and D- pins provides more reliability for the system.
