HUSB801【Integrated Buck Controller】 Expand all
Product Descriptions

The HUSB801 is a buck controller and supports USB Type-C and USB Type-A Dual-Port. When there is only one port attached, the fast charging protocols, USB PD or HVDCP, are enabled, it is only 5 V output when both ports are attached simultaneously. The HUSB801 is a USB PD3.1 controller which supporting 5 FPDOs and 2 APDOs with programmable current and voltage. Besides. The HUSB801 also supports BC1.2 DCP, Apple 2.4A, QC2.0/3.0/QC3+, AFC, FCP and SCP, PE1.1+ protocols. The HUSB801 integrates Chip-Link technology, which can be applied in a 4-port application. The HUSB801 integrates all of required protections such as Over Voltage Protection (OVP), Under Voltage Protection (UVP), Under Voltage Lockout (UVLO), Over Current Protection (OCP), Fast Over Current Protection (FOCP), CC or DPDM Over Voltage Protection (Port OVP) and Thermal Shut Down (TSD). It is QFN-40L (5 mm x 5 mm) package.
