FUSB303BTMX Description

Short technical summary and product information.

The FUSB303BTMX from On Semiconductor is a fully autonomous USB Type-C port controller optimized for low-power applications up to 15W. It adheres to the latest USB Type-C Specification Release 1.3, offering flexible configuration for Source, Sink, and Dual-Role Port (DRP) functionalities, including accessory detection and Dead Battery support.

 

This controller operates within a VDD range of 2.85V to 5.5V and features ultra-low power consumption, typically drawing less than 10µA. Configuration can be achieved via I2C for multi-port systems or through simple pin settings for autonomous operation. It provides robust protection with 4 kV HBM ESD tolerance on connector pins and a maximum 28V DC tolerance on critical detection pins.

 

The FUSB303BTMX is housed in a compact 12-lead QFN package measuring 1.6mm x 1.6mm x 0.375mm, making it suitable for space-constrained designs. Its versatile interface options, including GPIO and I2C, alongside USB 2.0 and USB 3.1 support, make it an ideal choice for a wide range of consumer electronics.

 

Applications include smartphones, tablets, laptops, power banks, and various accessories where efficient and reliable USB Type-C power delivery and data management are essential.
