概要
Description
USB5734T-I/MR is a USB hub/controller IC used to add multiple USB ports to a host system. It provides an upstream port to the host and one or more downstream ports, typically operating as a USB 2.0 Hi‑Speed hub (up to 480 Mbps) with integrated hub logic, power switching for downstream ports, and protection features (e.g., overcurrent/ESD). Configuration and status are accessed via a host interface (e.g., I2C/SPI, depending on variant). The “I/MR” suffix denotes industrial/reel-pack options (industrial temperature range and/or tape-and-reel packaging) suitable for embedded, automotive, and consumer applications. Common use cases include docking stations, card readers, and any system needing additional USB ports while maintaining USB spec compliance and robust power management. Typical prerequisites are a suitable 5 V supply, proper decoupling, and correct PCB layout to meet USB 2.0 electrical requirements.
Equivalent
I don’t have enough info to safely identify equivalents for USB5734T-I/MR. Please confirm the manufacturer and the chip’s function (USB controller, hub, switch, PHY, etc.) or upload the datasheet/part marking. With that I can list verified cross-references and drop‑in replacements.
Features
Here are typical features you’d expect for a USB5734T-I/MR USB hub controller (exact specs depend on revision; check the datasheet for your device):
- 4 downstream USB 2.0 ports + 1 upstream port (HS/FS) with hub functionality
- USB-IF compliant USB 2.0 hub controller with integrated transceivers
- I2C or SPI control interface for configuration and status monitoring
- Per-port power switches with programmable current limits and per-port over-current protection
- Total hub power management and role as a USB hub (no external host controller required)
- USB Battery Charging 1.2 support for charging downstream devices
- Suspend/Resume and Link Power Management (LPM) support; remote wakeup
- ESD protection on USB data lines; recommendations for external protection as needed
- Hot-plug detection and status indicators (LEDs or GPIOs)
- Low-power operation and thermal/power monitoring
- Industrial temperature variants (-I) and packaging options including tape-and-reel (-MR)
Note: exact I/O levels, current limits, and temperature range vary by part revision; verify with the specific datasheet for USB5734T-I/MR.
