Overview

Description

FUSB303BTMX is an USB Type-C Port Controller from ON Semiconductor. It provides CC line management and VBUS control for a USB‑C port and interfaces with a host MCU over I2C. Key functions include cable orientation detection (flip), attach/detach events, and basic role/port control, plus driving an external VBUS switch. It enables Type‑C functionality without a full USB PD stack; for full PD you typically add a separate PD controller. The TMX suffix denotes a specific package/variant of the device. Typical applications: USB‑C chargers, hubs/docks, power banks, and other devices needing a controllable USB‑C port. In short: a compact, I2C‑driven component to implement and control a USB‑C port with CC logic and power management.

Features

Here are the core features of FUSB303BTMX (USB-C port controller with PD):
- USB Type-C port controller with integrated PD negotiation
- Dual-Role Port (DRP) with automatic role swap (source/sink)
- CC line management for both CC1/CC2, including orientation detection
- VCONN support and VBUS control with protection
- VBUS discharge on detach; overcurrent/short-circuit and over/undervoltage protection
- USB Power Delivery contract negotiation to enable higher voltages/currents (up to the PD-contract limits)
- Programmable Rp values to advertise source current (Default, 1.5 A, 3.0 A)
- I2C interface for configuration and status monitoring (host MCU control)
- Interrupt/Status outputs for event signaling
- Low power/standby operation with wake-on-CC events
- Fault monitoring (thermal, overcurrent, overvoltage)
- Small TMX package suitable for compact designs
- Wide operating temperature range (typical industrial ranges)
Note: PD voltage/current capabilities depend on the implemented PD contract and system design.

Package

QFN-20 (leadless) package, 3×3 mm.

Pinout

- Pin count: 16 pins (BTMX package, QFN-16).
- Function: USB Type-C Port Controller with Power Delivery negotiation. It handles CC1/CC2 detection and Rp/Rd control, VBUS sensing, VCONN control, and provides an I2C interface (SDA/SCL) to a host MCU, along with status/interrupt pins (ALERT/EN).

Manufacturer

- Manufacturer: On Semiconductor (Onsemi).
- What kind of company: An American multinational semiconductor company that designs and manufactures energy-efficient silicon and system solutions for automotive, industrial, communications, consumer, and computing markets.

Application

- USB Type-C Power Delivery controllers for source/sink roles
- Used in USB-C chargers/adapters, power banks, docking stations, and multi-port hubs
- Automotive and consumer electronics ports requiring PD negotiation and VBUS control
- Any device needing CC line management, PD contracts, and safe VBUS switching

Equivalent

Equivalent USB‑C/PD controller options from other vendors:
- STMicroelectronics: STUSB4500, STUSB1602
- NXP Semiconductors: PTN5100, PTN5110, PTN5150
These provide similar Type-C cable/PD negotiation and role control as the FUSB303BTMX. Check datasheets for exact PD version, I2C interface, and package options.
