UPD301A

Not Recommended for new designs

The UPD301A is a stand-alone, small form factor USB Type-C® Power Delivery (PD) Port Controller designed to adhere to the USB Type-C Cable and Connector Specification and USB Power Delivery 3.0 Specification. The UPD301A provides stand-alone operation for source PD applications, enabling cable plug orientation and detection for a USB Type-C receptacle, and implementing baseband communication with a partner USB Type-C device via the integrated USB Power Delivery 3.0 MAC.The embedded 32-bit ARM Cortex-M0+ implements a full Power Delivery firmware stack, providing a turn-key solution for USB-C charge-only applications, and requiring minimal customer development. Configuration is supported via pin straps to select source functionality and PD power profiles. Optionally, a second PD port is supp...
