Microchip Technology USB7052 Interface ICs

Microchip Technology USB7052 Interface ICs are low-power, OEM configurable, USB 3.2 Gen 1 hub controller with 4 downstream ports. These interface ICs are fully compliant with the Universal Serial Bus Revision 3.2 specification and USB 2.0 Link Power Management Addendum. The USB7052 IC supports USB power delivery with up to 100W of power and alternate modes on the upstream port. These interface ICs enable OEMs to configure the system using "Configuration Straps". The USB7052 ICs are available in commercial 0°C to 70°C and industrial -40°C to 85°C temperature ranges. Applications include standalone USB hubs, laptop docks, PC motherboards, PC monitor docks, and multi-function USB 3.2 Gen 1 peripherals.
