The GL852GT is a USB 2.0 hub controller IC manufactured by Genesys Logic. It is a highly integrated chip designed to expand a single USB port into multiple ports, allowing users to connect more USB devices to their computer or other host device. This chip is commonly used in USB hubs, docking stations, and embedded systems.

Applications:

• USB hubs
• Docking stations
• Embedded systems
• Computer peripherals
• Consumer electronics devices

Features:

• USB 2.0 compliant: Supports high-speed (480Mbps), full-speed (12Mbps), and low-speed (1.5Mbps) data transfer rates.
• Four downstream ports: Provides four USB ports for connecting devices.
• Integrated USB transceiver: Reduces the need for external components, simplifying circuit design.
• Over-current protection: Protects the USB ports and connected devices from damage due to excessive current draw.
• Individual port power management: Allows for independent power control of each port, enabling power saving.

Benefits:

• Increased connectivity: Expands a single USB port into multiple ports, allowing for the connection of more devices.
• Simplified design: The integrated USB transceiver reduces the need for external components, making the design process easier.

• Cost-effective: Provides a cost-effective solution for adding USB connectivity to various devices.

Additional Details:

The GL852GT typically comes in a QFN (Quad Flat No-leads) package. It supports both bus-powered and self-powered modes. In bus-powered mode, the hub draws power from the USB host, while in self-powered mode, the hub uses an external power supply. The chip integrates a 5V to 3.3V regulator, simplifying power management. It also includes an internal oscillator, eliminating the need for an external crystal. The GL852GT supports various operating systems, including Windows, macOS, and Linux. It is widely used in a variety of USB hub designs due to its reliability and performance. The operating temperature range is generally from 0°C to 70°C.
