USB2513B/M2 - 3-Port USB 2.0 Hi-Speed Hub Controller | Microchip
MPN: USB2513B/M2 ✓ সক্রিয়USB2513B/M2 সারাংশ
A USB hub controller is a peripheral device that expands a single USB root port into multiple downstream ports, allowing several USB devices to share one upstream connection. USB hubs sit in the USB 2.0 protocol layer between the host controller and end devices, handling transaction translation, port power switching, and overcurrent protection. The USB2513B is part of the Microchip USB251xB/xBi family and is widely used in embedded and mobile designs where compact footprint and low BOM cost are critical.
Key features of the USB2513B/M2 include support for USB 2.0 Hi-Speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation, individual or ganged downstream port power switching with overcurrent protection, Battery Charging 1.1 (BC1.1) protocol support on downstream ports, programmable signal drive strength, internal 3.3 V regulator, integrated USB termination and pull-up/pull-down resistors, and on-chip ESD protection. The integrated MultiTRAK™ architecture delivers industry-leading throughput in mixed-speed USB environments by dedicating a transaction translator per downstream port.
The USB2513B/M2 is configured via SMBus or an external EEPROM, allowing OEMs to customize VID, PID, port disable map, and power-switch behavior without external logic. The 36-pin SQFN package provides a small PCB footprint suitable for space-constrained mobile and consumer products. The part is qualified for industrial temperature operation and is fully footprint-compatible with older USB251x/xA family members for direct drop-in upgrades.
Typical applications include USB port expansion in laptops, tablets, and docking stations, multi-port USB charging hubs, industrial PCs, embedded HMI panels, and consumer electronics such as monitors, set-top boxes, and game consoles. BC1.1 support makes it particularly attractive for dedicated charging-only ports without host interaction.
When designing with this device, place the 12 MHz crystal or clock source within 5 mm of the XTAL1/XTAL2 pins, and follow USB 2.0 high-speed layout guidelines including a 90-ohm differential impedance on DP/DM pairs. Decouple VBUS with a 4.7 uF ceramic capacitor and add ferrites upstream of each downstream port to pass USB-IF compliance testing.

USB Port Expansion in Laptops and Docking Stations
The USB2513B/M2 is widely used as a 3-port expansion hub inside laptops, ultrabooks, and Thunderbolt docking stations. Its 36-SQFN (6x6 mm) footprint fits inside the display hinge or baseboard area, while the integrated MultiTRAK™ architecture maintains full 480 Mbps throughput even when multiple downstream devices operate at mixed speeds (LS/FS/HS). The 3.0-3.6 V single-supply operation aligns with the laptop's main 3.3 V rail, eliminating the need for an extra LDO. BC 1.1 charging support enables downstream ports to deliver up to 1.5 A for fast-charging phones without host-side driver changes. Designers benefit from the integrated overcurrent protection that ties directly to the port power switches.

Multi-Port USB Charging Hubs and Wall Chargers
Dedicated charging hubs and wall chargers leverage the USB2513B/M2's BC 1.1-compliant downstream ports to deliver fast charging without an attached host. The integrated port power switches with overcurrent protection simplify thermal design by eliminating external MOSFETs, while ganged power-control mode reduces SMBus traffic for simple 3-port chargers. The internal 3.3 V regulator allows the part to run directly from a 5 V VBUS rail after a single ferrite bead and bulk capacitor, shrinking the BOM. Designers can disable the upstream USB transceiver to operate in dedicated charging mode, complying with USB-IF DCP specifications for Apple and BC 1.1 standards simultaneously.

Industrial PCs and Embedded HMI Panels
Industrial PCs, panel PCs, and human-machine interface (HMI) panels use the USB2513B/M2 to expose 3 USB 2.0 ports for connecting barcode scanners, keyboards, mice, and touchscreens. The industrial temperature variant (USB2513B-I/M2) operates from -40C to +85C, suitable for factory-floor and outdoor kiosk environments. The MultiTRAK™ per-port transaction translator prevents slow downstream devices from degrading the bandwidth of full-speed peripherals - critical when an HMI panel is paired with a USB camera and a low-speed keyboard simultaneously. Integrated ESD protection on the data lines survives ±8 kV HBM discharge events common during field installation.

Consumer Monitors and Set-Top Boxes
LCD monitors, smart TVs, and set-top boxes integrate the USB2513B/M2 to provide service ports, side-panel USB-A connectors, and side-band media reader interfaces. The 36-SQFN package fits on the main board next to the HDMI receiver, and the integrated pull-up/pull-down resistors eliminate external components. The hub can be configured via EEPROM at production time to disable unused ports, set custom VID/PID, and enable the BC 1.1 charging feature on certain ports - useful when the monitor's USB ports also power a streaming stick. The internal regulator draws only 3.3 V from the main supply, simplifying power tree design.

USB Port Replication in All-in-One Desktops
All-in-one desktop computers use the USB2513B/M2 to expand a single root port from the chipset into 3 user-accessible USB-A ports on the chassis. The MultiTRAK™ design keeps USB 3.0 root coexistence clean by isolating each downstream port's transaction translator, preventing bus contention when legacy 1.1 devices are connected. The part's low standby current (under 1 mA in suspend) supports ENERGY STAR and EuP lot 6 power requirements. Per-port overcurrent feedback signals connect directly to the embedded controller for graceful port shutdown messaging in the OS.

Automotive Infotainment and Head Units
Although the USB2513B/M2 itself is commercial-grade, automotive aftermarket head units and rear-seat entertainment systems use it for USB media port replication. Designers select the USB2513B-I/M2 industrial variant when targeting harsh under-dash environments. The integrated port power switching and overcurrent protection are critical for automotive load-dump and short-to-battery events. BC 1.1 charging lets passengers fast-charge phones while audio is streaming, and the MultiTRAK™ architecture supports simultaneous USB stick playback and a connected Bluetooth dongle at full bandwidth without data loss.

ডিজাইন নোট
USB 2.0 Hi-Speed signals require 90 ohm differential impedance on the DP/DM pairs. Route the upstream and all 3 downstream pairs with continuous reference ground on the layer directly below, no splits under the traces. Keep differential pairs length-matched within 150 mil. Place the 12 MHz crystal within 5 mm of XTAL1/XTAL2 and surround it with a ground guard ring. Per the Microchip datasheet, the exposed thermal pad (EP) MUST be soldered to a grounded copper pour of at least 0.5 square inch to meet USB-IF thermal-rise requirements during sustained HS traffic.
Decouple VDD33 (pins 1-2) with a 4.7 uF X5R ceramic plus a 0.1 uF X7R ceramic placed within 2 mm of the pins. Add a ferrite bead on each downstream VBUS line upstream of the port power switch to suppress conducted emissions. The internal 3.3 V regulator (VBAT pin) requires a 1 uF bypass on its output. Estimated: at 480 Mbps full load, the part draws approximately 100 mA from VDD33, leaving significant margin for the port power switches at 500 mA per port typical.
Do not leave the TEST pin floating - tie TEST directly to GND for normal operation. The CFG_SEL0/CFG_SEL1 pins select between SMBus-managed, EEPROM-managed, and pin-strapped configurations; if these pins are left floating, the part may enter an undefined startup state. The SDA/SCL lines need 4.7 kohm pull-ups to VDD33 even when no EEPROM is attached. For BC 1.1 charging, the port power switch must remain on during charging even when upstream is suspended - configure this in the SMBus registers before first power-up.
