USB2512BT/M2 - 2-Port USB 2.0 Hub Controller | Microchip
部品番号: USB2512BT/M2 ✓ 生産中USB2512BT/M2 概要
A USB hub controller is an interface IC within the broader USB interface and semiconductor hierarchy. It manages traffic between a host and multiple downstream peripherals, coordinates downstream-port power, and helps maintain compliant behavior in a USB 2.0 topology. The USB2512BT/M2 uses Microchip MultiTRAK technology, a family approach designed for efficient USB 2.0 hub operation in mixed-speed environments.
Verified product information identifies support for USB 2.0 Hi-Speed operation, two downstream ports, a 3 V to 3.6 V supply range, and a 60 mA operating-current figure. Integrated functions include an internal regulator, downstream-port power-switch control, overcurrent protection, ESD protection, programmable signal drive, and support for USB Battery Charging 1.1 protocol operation. These functions reduce the amount of external control logic required in a compact hub implementation.
The 36-SQFN package is designed for surface mounting and supports compact PCB layouts, but the exposed thermal and electrical characteristics still require careful layout according to the manufacturer datasheet. The available web records describe the device as active. The supplied comparison record lists an 85 °C maximum operating temperature for the USB2512BT/M2, while several other detailed limits remain unavailable in the retrieved source material.
Typical uses include compact USB 2.0 docking stations, embedded host accessories, printer interfaces, portable equipment, and industrial peripheral connectivity. The two-port topology is appropriate where a host interface must be shared by two downstream devices without introducing another external hub controller. System designers must still verify USB enumeration, power-budget, and downstream-device compatibility requirements.
The principal design consideration is power management. Port power-switch control and overcurrent protection should be coordinated with the required downstream current budget, while internal-regulator and decoupling requirements must follow the manufacturer reference design. Signal-routing practice should preserve USB differential-pair geometry and provide the required protection and connection details.
This page consolidates the verified USB2512BT/M2 specifications, distributor availability records, package information, and same-family replacement data. It also separates confirmed parameters from unavailable technical details and identifies the engineering trade-offs that matter when comparing a two-port USB 2.0 hub controller with other hub implementations.

主な用途
USB2512BT/M2 の用途: 6 件s: Compact USB 2.0 Docking Station, Industrial USB Peripheral Hub, Portable USB Accessory Hub, Printer and Storage Interface Hub, USB-to-Serial Service Interface, Embedded USB Expansion Board.
Compact USB 2.0 Docking Station
The USB2512BT/M2 fits a compact docking station that exposes one upstream USB 2.0 connection and two downstream ports. Its verified 3 V to 3.6 V supply range aligns with a 3.3 V system, while the 36-SQFN 6 mm × 6 mm package helps limit board area. The controller can manage two downstream devices through USB 2.0 Hi-Speed operation. Integrated downstream-port power-switch control, overcurrent protection, ESD protection, programmable signal drive, and an internal regulator reduce the amount of supporting circuitry required around the hub. The implementation must still confirm connector data-rate requirements, downstream current allocation, charging behavior, and USB enumeration before release.
おすすめ
Industrial USB Peripheral Hub
The USB2512BT/M2 can support an industrial peripheral hub where a single USB host must connect two downstream devices. Its two-port USB 2.0 Hi-Speed architecture and integrated overcurrent and ESD protection address common interface requirements, while the internal regulator simplifies the local power structure around the controller. The verified 85 °C maximum operating-temperature figure provides a defined upper limit for enclosure planning. Actual industrial suitability depends on the minimum temperature grade, EMC requirements, isolation needs, and fault-recovery behavior, none of which were fully available in the retrieved data.
おすすめ
Portable USB Accessory Hub
The USB2512BT/M2 is appropriate for a portable accessory that needs to consolidate two USB peripherals behind one host port. The small 36-SQFN package supports space-constrained construction, and the controller’s 3 V to 3.6 V operating range is compatible with regulated 3.3 V rails commonly used in portable equipment. Programmable signal drive can assist with system-level USB signal tuning, while port-switch control and overcurrent protection help isolate downstream faults. A portable design must additionally validate sleep current, battery-current budget, connector mechanical requirements, and the interaction between downstream charging loads and the system power source.
おすすめ
Printer and Storage Interface Hub
The USB2512BT/M2 can serve as the central controller in a printer or storage accessory that presents two downstream USB 2.0 devices to a host computer. USB 2.0 Hi-Speed operation provides a suitable interface for many printers, mass-storage devices, and control peripherals, while downstream power-switch control allows individual ports to be managed by the system. The internal regulator, programmable signal drive, ESD protection, and overcurrent protection support a compact implementation. Engineers must verify the actual transfer rates, attached-device power requirements, hot-plug behavior, cable lengths, and whether USB Battery Charging 1.1 support is necessary for the intended devices.
おすすめ
USB-to-Serial Service Interface
The USB2512BT/M2 can be combined with a USB-to-serial bridge to create a service interface that exposes one legacy or diagnostic connection and one additional USB peripheral port. Its two-port topology provides flexible routing while preserving USB 2.0 Hi-Speed compatibility. A CP2102N family bridge can implement the serial side, while the hub controller manages downstream port power, fault protection, and programmable USB signal drive. The design should confirm whether both ports must enumerate simultaneously, how legacy device signaling is translated, and whether the service interface needs galvanic isolation or independent brownout behavior.
おすすめ
Embedded USB Expansion Board
The USB2512BT/M2 is suitable for an embedded expansion board that increases USB connectivity without using a host PC. The controller supports two USB 2.0 Hi-Speed downstream ports, a 3 V to 3.6 V supply range, and integrated power-management functions in a surface-mount package. A low-power microcontroller can configure hub behavior and report status, while an AT90USB646-class USB device can provide the downstream-facing logic. Board-level validation should include heat dissipation, input and output capacitance selection, connector placement, ESD return paths, and confirmation that the enclosure does not exceed the verified 85 °C maximum operating temperature.

設計ノート
Budget the USB supply path from the host, connector, protection devices, and each downstream load rather than using only the verified 60 mA USB2512BT/M2 operating-current figure. The controller includes port power-switch control, an internal regulator, and overcurrent protection, but those functions do not remove the need to validate the downstream current budget. Use the manufacturer reference schematic and datasheet limits for capacitor selection, power-switch current ratings, and fault behavior.
Place USB differential pairs according to the manufacturer layout guidance and keep the upstream and downstream routes away from noisy switching nodes and connector return transients. The supplied search results do not provide the complete 36-pin map, exposed-pad connection, or recommended PCB stack-up, so those details must be taken directly from the current USB2512B datasheet. Do not infer pad assignments from another family member without checking the orderable-part table.
Do not treat the USB2512BT, USB2512BT-I, USB2512B, and USB2512BI order codes as automatically interchangeable. Although the retrieved records connect them to the same Microchip family and 36-SQFN format, suffix changes may affect temperature grade, qualification, package option, or ordering conditions. Compare the complete manufacturer orderable-part table and verify lifecycle status before using any alternative in a released design.
Give ESD and overcurrent protection paths short, direct return routes to the relevant power or ground reference. Connector-generated ESD events and downstream hot-plug transients can disturb USB signals even when the controller includes internal protection. Confirm which protection is internal and which external components are required, then follow the manufacturer reference layout for ESD capacitance, trace geometry, and grounding.
