描述 Description

The STUSB4710 is a new family of USB power delivery controllers communicating over Type-C? configuration channel pins (CC) to negotiate a given amount of power to be sourced to an inquiring consumer device.

The STUSB4710 addresses provider/DFP devices such as notebooks, tablets and AC adapters. The device can handle any connections to a UFP or DRP without any MCU attachment support, from the device attachment to power negotiation, including VBUS discharge and protections.

? Configurable start-up profiles
? Integrated VBUS voltage monitoring
? Internal and/or external VBUS discharge path
? Short -to-VBUS protections on CC pins (22 V) and VBUS pins (28 V)
? Wide power supply input:
?VDD = [4.1 V; 22 V]
? Temperature range: -40 °C up to 105 °C
? Fully compatible with:
?USB Type-C? rev 1.2
?USB PD rev 2.0
? Certification test ID: 1000125 (QFN24)

簡介

STUSB4710屬于集成電路（IC）的控制器。由制造生產(chǎn)的STUSB4710控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點之間提供信息連接。示例包括將 I2C 總線連接到 UART，將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外，還包括用于通過為點對點通信設計的接口建立多路連接的器件，例如 USB 集線器控制器。
