概述

Description

FUSB307BMPX is a USB Type-C Port Controller (FUSB family) used to manage a USB-C port without a separate PD stack. It provides CC-line detection and orientation logic, basic power-role signaling, and VBUS protection through external switches. It monitors CC1/CC2, advertises the desired current (Rp/Rd), senses VBUS, and offers fault protection (over/short circuit, over/under-voltage) with status/interrupt outputs. The device typically interfaces to a host MCU via I2C/SMBus for configuration and status reporting. The BMPX suffix denotes a compact, small-footprint package. Applications include USB-C ports on chargers, power banks, hubs, and other devices needing a low-cost, robust Type-C interface.

Features

Here are the typical features of the FUSB307BMPX USB-C port controller (concise):
- USB Type-C port controller with CC logic for CC1/CC2 detection and cable orientation
- Dual-role port (DRP) support: can act as source or sink (auto or forced role)
- Rp/Rd current advertisement using 56k/22k/10k options (Default, 1.5A, 3.0A)
- I2C control interface for configuration, status, and monitoring
- VBUS sensing and protection (monitoring up to VBUS, overcurrent protection, short-circuit protection)
- VBUS discharge path when a cable/attach is removed
- ESD protection on CC pins and robust input protection
- Small BMPX package with low quiescent power; wide operating voltage (typ. 1.65–5.5 V)
- Operating temperature generally suitable for consumer/mobile applications (typ. -40°C to 85°C)
Note: This is a concise feature summary based on typical FUSB30x family capabilities; verify against the exact datasheet for FUSB307BMPX for precise specs.

Package

It’s in a QFN-16 package (3.0 mm × 3.0 mm) with an exposed pad. This is the SMT package code BMPX.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: USB Type-C port controller (FUSB307). Provides CC logic for USB-C detection/orientation, VBUS/VCONN control and protection, typically interfaced to a host MCU via an I2C-style control interface for USB-C power delivery/negotiation.

Manufacturer

- Manufacturer: ON Semiconductor (Onsemi).
