What are the key features of USB2514B-AEZG?
- USB 2.0 Hi-Speed 4-port hub controller supporting 480 Mbit/s per-port bandwidth with transaction translator for full-speed and low-speed device compatibility
- Integrated I2C and SMBus interface enabling flexible runtime configuration of port power management, VID/PID customization, and over-current thresholds
- VQFN-36 package (6 mm × 6 mm) with exposed thermal pad simplifying PCB integration in space-constrained docking stations and embedded systems
- Low standby power consumption with per-port power switching supporting USB Battery Charging Specification revision 1.2 for downstream charging
- Single 3.3 V supply operation with internal voltage regulators reducing external power-rail requirements and bill-of-materials complexity
What is USB2514B-AEZG used for?
The USB2514B-AEZG is designed for embedded USB expansion in industrial computers, single-board computers, and docking stations that need to extend a single upstream USB 2.0 port into 4 independently managed downstream ports at 480 Mbit/s. Its I2C/SMBus configuration interface allows host firmware to customize VID/PID strings, set per-port current limits, and enable power switching, making it ideal for kiosk terminals, POS systems, and medical imaging peripherals. The compact VQFN-36 footprint and USB Battery Charging 1.2 support also suit tablet accessory hubs and automotive infotainment USB expansion modules.

Frequently Asked Questions
How many downstream USB ports does the USB2514B-AEZG support, and at what data rate do they operate?
The USB2514B-AEZG provides 4 downstream USB 2.0 ports, each capable of Hi-Speed operation at 480 Mbit/s. It includes a transaction translator to support legacy full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) devices simultaneously without degrading bandwidth on the other ports. This makes it suitable for mixed-device environments in industrial and consumer applications.
What configuration interface does USB2514B-AEZG use, and what parameters can be set at runtime?
The USB2514B-AEZG exposes an I2C and SMBus interface running at up to 400 kHz for runtime configuration. Through this interface, the host can customize the USB Vendor ID and Product ID strings, set per-port over-current detection thresholds, enable or disable individual downstream ports, and control USB Battery Charging Specification 1.2 charging profiles. Configuration registers can also be pre-loaded from an external EEPROM at startup.
What supply voltage does USB2514B-AEZG require, and what is its operating temperature range?
The USB2514B-AEZG operates from a single 3.3 V supply rail with internal regulators generating the required 1.8 V core voltage, simplifying power design. The device is rated for the commercial operating temperature range of 0°C to +70°C, making it appropriate for indoor embedded and consumer electronics environments rather than harsh industrial or automotive deployments.
How does USB2514B-AEZG handle per-port power switching and over-current protection for downstream devices?
The USB2514B-AEZG supports ganged or individual per-port power switching through external power-switch ICs controlled by dedicated GPIO outputs, allowing each of the 4 downstream ports to be independently powered or shut down in software. Over-current detection inputs accept threshold signals from external sense resistors or dedicated power-switch fault pins, triggering automatic port shutdown within 8 ms to protect both the hub and the host from fault conditions.
What PCB area does the VQFN-36 package of USB2514B-AEZG occupy, and does it support reflow soldering?
The VQFN-36 package measures 6 mm × 6 mm with a 0.5 mm pin pitch and an exposed thermal pad on the bottom, occupying only 36 mm² of PCB board area. The package is fully compatible with standard lead-free SAC305 reflow soldering at peak temperatures up to 260°C and carries JESD-609 code e3, indicating compliance with RoHS and Pb-free assembly processes.
