概述

Description

TPS25730DREFR is TI’s USB Type-C port controller. It provides the CC1/CC2 logic, orientation/detect, and current advertisement for a USB-C port, and it drives external FETs to control the VBUS path and VCONN as needed. It handles attach/detach events, safety protections (overcurrent, short-circuit, overvoltage, thermal), and optional dead-battery operation. The device communicates with a host or microcontroller via I2C to report status and receive control signals, while a separate PD controller (if needed) can handle USB PD negotiation. The DREFR suffix indicates the product in a D-package with tape-and-reel packaging. Applications include USB-C ports on chargers, laptops, docking stations, and consumer electronics that require compliant CC handling and VBUS control without full USB PD functionality.

Features

TPS25730DREFR features (TI USB Type-C Port Controller with VBUS switch)
- USB Type-C port controller with integrated VBUS switch and protection
- CC1/CC2 detection for plug orientation and role determination
- Configurable current advertisement (Rp/Rd) for USB-C port power capabilities
- I2C interface for register configuration and status monitoring
- Integrated VBUS discharge control and hot-plug/attach detection
- Overcurrent (OC), short-circuit, overvoltage, undervoltage, and thermal protections
- Low standby current with fast response for power management
- Suitable for 5 V USB-C sources/loads; operation across typical Type-C voltage range
- Fault reporting via status/interrupt outputs and programmable rules
- Small package option (DREFR indicates tape-and-reel packaging variant)
Note: For exact electrical specs (current limits, timing, register map), consult the TPS25730 data sheet.

Package

TPS25730DREFR uses the DRE package: a 16-pin QFN (3×3 mm) with an exposed pad, RoHS/Pb-free.

Pinout

- Pin count: 16 pins (DRE package).
- Function: USB Type-C Port Controller. It monitors CC1/CC2, detects attach/detach and orientation, and drives the external VBUS power-path FETs (and VCONN as needed) to enable/disable VBUS with protection features.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: American multinational semiconductor company that designs and manufactures analog, embedded processing, and related integrated circuits for a wide range of electronics markets.

Application

- USB-C power delivery sources and sinks (5–20 V)
- USB-C chargers, wall adapters and power banks
- USB-C hubs, docking stations and notebook/tablet ports
- Embedded/portable devices needing CC negotiation and VBUS control (DRP)
- Systems requiring VBUS protection (OCP/OVP/SCP) and fast role switch

Equivalent

Equivalent USB-C port controllers with I2C from other vendors include:
- STMicroelectronics STUSB4500 / STUSB4700
- On Semiconductor FUSB302 / FUSB302P
- NXP PTN5100 / PTN5110
- Cypress/Infineon CYPD-series USB-C controllers
Note: PD support, current rating, package, and I2C interface vary—verify datasheets for exact parity with TPS25730DREFR.
