Descripción general

Description

FUSB251UCX is a USB Type-C port controller IC used to manage the CC pins and basic USB‑C negotiation in devices that do not implement full USB Power Delivery.
Key points:
- Provides CC1/CC2 control, orientation detection, and attach/detach sensing.
- Configurable current advertisement via Rp/Rd (advertised current levels depend on configuration).
- Communicates with a microcontroller over I2C for status, events, and configuration; can generate interrupts to the MCU.
- Used to enable/disable a VBUS path through a power switch or external circuitry (control of when power is allowed to flow).
- Intended for simple USB‑C ports in chargers, hubs, or devices requiring Type‑C connectivity without PD negotiation.
- Not a PD controller; does not negotiate higher voltages or USB PD power contracts.
Package UCX indicates the specific physical package type. In summary, FUSB251UCX simplifies implementing a standard USB‑C receptacle/port without PD, handling detection, current advertisement, and MCU communication.

Features

Here are the key features of the FUSB251UCX (USB Type-C Port Controller):
- USB Type-C CC logic with I2C control (no PD negotiation)
- Detects attachment and CC line orientation (CC1/CC2)
- Dual‑role support: source or sink via programmable Rp/Rd
- Rp values to advertise current capability (e.g., 56k/22k/10k for Default/1.5A/3A)
- VBUS monitoring and controlled discharge on detach
- Interrupt/status outputs for MCU (attach/detach, orientation, role changes)
- Fault protection and safe operation (overcurrent/fault reporting)
- Small UCX 8‑pin package; RoHS compliant
- Wide supply range: approximately 2.7–5.5 V
- Operating temp typically −40 to 85°C
Use: USB-C port control and power-path management for Type-C ports (without full USB PD).

Package

FUSB251UCX is an 8-pin UQFN (UCX) package, typically 3×3 mm with an exposed pad.

Pinout

- Pin count/package: 16 pins in UCX (QFN-16, ~3x3 mm)
- Function: USB Type-C Port Controller. It monitors CC1/CC2 for attach/orientation, handles role/current advertising for the USB-C port, and controls external VBUS FETs. It does not implement full USB Power Delivery negotiation.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semi), often listed as ON Semiconductor.
- What kind of company: An American multinational semiconductor company that designs and manufactures a broad range of silicon ICs and sensors for automotive, industrial, communications, and consumer markets.

Application

- USB Type-C port controller for CC logic and PD in USB-C devices
- USB-C PD sources/sinks (5–20 V): chargers, power banks, laptops
- USB-C hubs, docking stations, adapters, and display docks
- Smartphones/tablets with USB-C PD
- Automotive/embedded electronics needing CC negotiation and safe VBUS control

Equivalent

Equivalent USB‑C port controllers to FUSB251UCX (PD/DRP capable options):
- STMicroelectronics: STUSB4500, STUSB4700
- Texas Instruments: TUSB320, TUSB1002
- NXP Semiconductors: PTN5100A, PTN5110
- Cypress/Infineon: CYPD3xx/CYPD5xx family (e.g., CYPD3120)
- On Semiconductor: FUSB302 (alternative in the FUSB family)
Note: PD features and DRP behavior vary by device; check datasheets for exact capabilities.
