GL850G-HHY22 概要
A USB 2.0 hub controller is an interface IC that sits between a USB host and one or more downstream USB devices, repeating and managing traffic according to the Universal Serial Bus Specification Revision 2.0. Hub controllers fall within the broader hierarchy of USB interface controllers, peripheral ICs, and semiconductors, and are fundamental building blocks in any system that needs to expand a single USB port into several.
The GL850G embeds an 8-bit RISC processor that manages control and status registers and responds directly to requests from the USB host, offloading hub transaction translation from the host CPU. It is Genesys Logic's advanced, cost-optimized hub solution and complies fully with USB Specification Revision 2.0, supporting low-speed (1.5 Mbps), full-speed (12 Mbps), and hi-speed (480 Mbps) devices. Power management supports both Individual and Gang modes across the four downstream ports, with two-color (green/amber) port status indication for LED-based port state feedback.
Architecturally, the GL850G inherits Genesys Logic's cost- and power-efficient serial interface design, delivering proven compatibility and a low-power profile compared with competing hub solutions. Its integrated RISC core and minimal external component count help system integrators achieve the lowest possible BOM (Bill of Materials) for motherboards, monitors, docking stations, and standalone USB hubs.
Typical applications include standalone multi-port USB hubs, PC motherboard front-panel and rear-panel USB port expansion, monitor and display USB uplink ports, embedded systems, and industrial equipment requiring reliable USB 2.0 port multiplication. For systems requiring higher full/low-speed performance with multiple transaction translators, Genesys Logic offers the GL852G multi-TT hub family.
Design considerations: provide clean 3.3V and 5V rails within the specified 4.75V to 5.25V and 3V to 3.6V windows, and observe the 0C to +85C commercial operating range. Proper crystal or oscillator placement and USB differential pair routing (90-ohm matched) are essential for passing USB-IF signal integrity compliance.

主な用途
GL850G-HHY22 の用途: 6 件s: Standalone 4-Port USB 2.0 Hubs, PC Motherboard USB Port Expansion, Monitor and Display USB Uplink, Embedded Systems and SBC Expansion, Docking Stations (GL850G class), Repair and Legacy Board Replacement.
Standalone 4-Port USB 2.0 Hubs
The GL850G-HHY22 is the classic core of standalone multi-port USB 2.0 hubs, expanding one upstream 480 Mbps port into four downstream ports. Its embedded 8-bit RISC processor handles all hub enumeration and host requests autonomously, so no external microcontroller is needed. Individual and Gang power management modes let the hub switch or manage port power per-port or as a group, while two-color green/amber LED outputs provide standard port status indication. Because it fully complies with USB Specification Revision 2.0 and uses minimal external components, the resulting hub BOM is among the lowest achievable for this product class.
おすすめ
PC Motherboard USB Port Expansion
Motherboard designers use the GL850G-HHY22 to multiply a chipset USB 2.0 port into additional front-panel or rear-panel ports. Operating within the ATX 5V and 3.3V rails (4.75V to 5.25V and 3V to 3.6V), it integrates directly with existing power delivery, and its 0C to +85C range covers typical desktop environments. The device's proven compatibility record, cited by Genesys Logic as among the best of any USB 2.0 hub solution, minimizes USB-IF certification risk on high-volume board designs. Its gull-wing SSOP-28 footprint is compatible with standard SMT assembly lines and supports reflow soldering in mass production.
おすすめ
Monitor and Display USB Uplink
Monitors frequently include a built-in USB hub so a single upstream cable from the PC serves several downstream ports on the display bezel or stand. The GL850G-HHY22 fits this role with its single-chip 4-port architecture and low external component count, which matters in the tight mechanical and cost budgets of display electronics. Its hi-speed 480 Mbps throughput supports flash drives and card readers attached to the monitor, while its LED status outputs integrate with on-screen-display-controlled indicator schemes. The dual-rail supply maps neatly onto monitor power boards that already generate 5V and 3.3V rails.
おすすめ
Embedded Systems and SBC Expansion
Single-board computers and embedded controllers often expose only one or two USB 2.0 host ports; the GL850G-HHY22 multiplies these for Wi-Fi dongles, USB-to-serial adapters, storage, and human-interface devices. Its 8-bit RISC core offloads hub transaction handling from the host processor, and its full compliance with USB Specification Revision 2.0 ensures enumeration on Linux, Windows, and RTOS host stacks without custom drivers. Low power consumption, inherited from Genesys Logic's cost- and power-efficient serial interface design, suits battery- and fanless-embedded products where every milliamp counts.
おすすめ
Docking Stations (GL850G class)
For cost-sensitive docking stations where attached devices are mostly hi-speed (storage, video capture), the single-TT GL850G-HHY22 provides an economical hub stage, while bandwidth-critical mixed full/low-speed designs can move to the multi-TT GL852G family from the same vendor. The GL850G's Individual power management mode supports per-port overcurrent and power switching demanded by docking platforms, and Gang mode simplifies designs that switch all ports together. Its 4.75V to 5.25V and 3V to 3.6V operating windows match standard dock power trees derived from laptop or adapter 5V inputs.
おすすめ
Repair and Legacy Board Replacement
The GL850G-HHY22 is a common service part for repairing USB hub circuitry on motherboards, monitors, and game handhelds where the original hub controller has failed. Community-repair experience, including documented GL850G-to-GL852G swaps, confirms the family's replaceability in existing footprints. Its commercial 0C to +85C rating and standard SSOP-28 gull-wing package make hot-air or reflow replacement straightforward with standard bench equipment. When repairing, always verify the board's expected default firmware revision (Y22 versus Y60, for example) so host-side enumeration identifiers remain consistent with the product's driver expectations.

設計ノート
Supply the GL850G-HHY22 from two regulated rails: 5V within 4.75V to 5.25V (typically derived from host VBUS through a power switch or ferrite) and 3.3V within 3V to 3.6V generated by an LDO such as an AMS1117-3.3. Place 10uF bulk plus 0.1uF ceramic decoupling capacitors close to each supply pin. Per-port downstream VBUS should be switched and current-limited in Individual mode using a dedicated USB power switch with overcurrent reporting back to the hub controller.
Route the upstream and four downstream USB 2.0 differential pairs as 90-ohm matched pairs with length matching within 5 mils, avoiding crossing plane splits and keeping pairs away from clock and crystal traces. The 12 MHz crystal must sit within a few millimeters of the device with correct load capacitors per the Genesys Logic datasheet reference design. Adhering to the datasheet's typical application layout is the fastest path to passing USB electrical compliance testing.
Version suffixes matter: GL850G Y22, Y37, and Y60 revisions can carry different default firmware behavior, and community reports note that switching between versions may require configuration changes. Verify the default VID/PID and behavior against your host drivers before substituting revisions on an existing PCB. Also observe the 0C to +85C commercial temperature range; do not deploy in extended-temperature enclosures without vendor qualification.
Use the exposed routing guidance from the manufacturer reference design: keep the SSOP-28 footprint pads per standard SSOP-28 land pattern, provide a solid ground plane under the USB pairs, and place LED series resistors so the two-color green/amber status lines remain short and away from the differential pairs. A 2-layer board is sufficient for a 4-port hub if the ground plane is uninterrupted beneath all USB routing.
