Interface Chip Simplifies USB Type-C And Power-Delivery Mess

STMicroelectronics released a new solution for USB Type-C and Power Delivery, the STUSB16 interface IC aimed at clearing the mess of cables used to charge and connect computers, smartphones, tablets, TVs, set-top boxes, gaming platforms, and a broad range of consumer, industrial, and IoT smart devices.

The USB Type-C connector and new standard Power Delivery modifies the USB ecosystem from a data interface capable of supplying limited power to a primary provider of power that includes a well-proven and widely adopted data interface. The connector offers reversible plug orientation and cable direction, delivering data rates up to 10Gbps and power up to 100W, making it ideal for consolidating numerous cables.

The interface IC integrates short-circuit, over-voltage, over-current protection, eliminating the need for external circuitry. Additionally, it offers plug power support (VCONN) with up to 600mA programmable current capability and, per the USB Power Delivery specification, it integrates Bi-Phase Mark Coded (BMC) Physical Layer (PHY) coding and decoding logic.

The USB Type-C and power delivery solutions include STM32 microcontroller, ESD protection devices, and power-management products. The new STUSB16 family also embeds higher levels of circuit protection and a customer-configurable non-volatile memory, which enables IC configuration at power-up without software support. Overall, the solution is able to achieve low BOM cost and flexible hardware/software solution for every power-profile requirement and customisation need.

ST has enabled the migration to the USB Type-C port through the simple addition of an STUSB16 companion chip to existing MCU-based designs, while minimising MCU-resource requirements compared to alternate solutions. Together these features simplify software development and reduce time-to-market while allowing customers to focus on their own added-value differentiators.
