概述

Description

FUSB3301MPX is an ON Semiconductor USB Type-C Port Controller (TCPC) in the FUSB family. It provides essential Type-C port management to a microcontroller.
Key points:
- CC logic and orientation detection (CC1/CC2) to determine plug direction and current capability.
- Port role control (source/sink) and VBUS enable/disable with protection.
- VCONN control and basic fault protections (short-circuit, over-current, undervoltage) for the USB-C port.
- MCU interface via I2C for configuration and status reporting.
- Typically used to implement USB-C receptacles/ports in devices like phones, tablets, laptops, power adapters, docking stations, and battery packs.
- Note: It may not perform full USB Power Delivery negotiation by itself; for PD you usually pair it with a separate PD controller or controller block.
In short, FUSB3301MPX handles the mechanical/electrical bring-up and policy of a USB-C port, while the MCU (and optionally a PD controller) handles higher-level protocol needs.

Features

Key features of FUSB3301MPX (USB Type-C Port Controller):
- Single-port USB Type-C port controller with CC logic for USB-C connectivity
- Dual-Role Port (DRP) support with automatic role detection/swapping
- Cable orientation detection via CC1/CC2; VCONN support
- Configurable Rp/Rd current advertisement (typical values for 500 mA/1.5 A/3 A equivalents)
- I2C control interface for configuration and status reporting (with interrupt/alert output)
- VBUS sensing and protection: overcurrent/short-circuit protection, fault latching
- VBUS monitoring, voltage/current sensing, and safe-power switching
- Low power standby and fast response for events
- Suitable for compact MPX package (integration-friendly)
Note: Exact electrical specs (voltage range, current limits,-I2C addresses, temp range) are in the datasheet; consult it for precise numbers.

Package

QFN-16 (3x3 mm) surface-mount package.

Pinout

- Pin count: 28 pins (MPX package).
- Function: USB Type-C port controller with Power Delivery negotiation. It handles CC1/CC2, orientation/role detection, VCONN/VBUS control, and provides an interface (I2C) to a host MCU for PD configuration.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corp.)
- What kind of company: An American multinational semiconductor company that designs, manufactures, and markets a broad range of energy-efficient integrated circuits and semiconductor solutions (acquired Fairchild Semiconductor in 2016).

Application

FUSB3301MPX is a USB Type-C port controller for CC line management, VBUS control, and orientation/role detection. Applications include USB‑C chargers and adapters, power banks, USB‑C hubs/docking stations, laptops/tablets with Type‑C ports, embedded/mobile devices, and automotive/industrial equipment needing safe USB‑C connection management.

Equivalent

Equivalent devices are other USB-C port controllers with CC logic (PD support varies by part). Common options include:
- STMicroelectronics STUSB4500 (PD-capable USB-C controller)
- STMicroelectronics STUSB1602 (USB-C CC logic)
- Texas Instruments TUSB320 (CC controller, no PD)
- NXP PTN5110/PTN5111 (USB-C port controllers)
- On Semiconductor FUSB302 (CC controller, PD-less)
Note: exact equivalence depends on PD support, current rating, and packaging.
