ONFUSB302B11MPX
Overview
The FUSB302B11MPX is a programmable USB Type-C controller with Power Delivery (PD) capabilities designed to handle both Source and Sink roles. It implements the physical layer (PHY) of the USB PD protocol, allowing a host processor to manage power negotiations via a standard I2C interface. This specific variant comes in a 14-lead MLP package and supports high-voltage operation up to 21V on the VBUS-related pins.
Why Choose This Part
The FUSB302B series is highly flexible as it offloads the PD state machine to the system microcontroller, allowing for easier updates to PD specifications. It features a low standby current of 25 uA and a compact 2.5 mm x 2.5 mm footprint, making it suitable for space-constrained battery-powered designs.
Applications
Key Specifications
Getting Started
Engineers can evaluate the device using the FEBFUSB302B_CH01UMX evaluation board or by integrating the onsemi-provided open-source PD firmware into their existing MCU project. Communication is handled via I2C, requiring a host controller to manage the protocol's policy engine and device policy manager.
