UPD301B/C USB Interface ICs Microchip Technology UPD301B/C USB Interface ICs are designed to adhere to the USB Type-C™ cable and connector specification and USB Power Delivery 3.0 (PD) specification. These ICs are stand-alone and offer a small form factor USB Type-C™ Power Delivery port controller. These ICs are integrated PD solutions with SAMD20 (32-bit ARM Cortex-M0+) microcontroller and UPD350 PD MAC/PHY functionality. The UPD301B/C integrates many analog discrete components required for USB Type-C PD applications, including two VCONN FETs with Rp/Rd switching. Applications include point-of-sale terminals, charging lockers, IoT products and sensors, smart speakers, monitors, conference systems, power tools, multi-port charging docks, and automotive rear seat charging ports.
