USB5807CT/KD Overview
A USB hub controller is a specialized interface IC that aggregates one upstream USB port into multiple downstream ports while handling the protocol stack, port power management, and traffic scheduling. SmartHubs add OEM-configurable firmware layers (MultiTRAK, flexPORT, PortSplit) on top of the standard hub state machine, enabling per-port behavior tuning, custom charging profiles, and signal-integrity adjustments without external logic. Within the broader IC hierarchy, USB5807CT/KD belongs to Interface ICs > USB Hubs > USB 3.x Hub Controllers > Power-Managed SmartHub family.
Key features include 7 downstream ports configurable as USB 3.2 Gen 1 or USB 2.0, native USB Type-C support via integrated MUX logic, MultiTRAK and PortSplit technology for per-port tuning, I2C and SPI host management interfaces, and Broadcom/Microchip-proprietary low-power states with optimized thermal dissipation. The VQFN-100 package provides a compact 12 mm x 12 mm footprint suitable for embedded designs and dock/monitor applications where board area is constrained.
The device uses a low-power architecture with embedded USB 3.x PHYs and a configurable hub feature ROM accessed via SPI. PortSplit allows simultaneous USB 3.x and USB 2.0 operation on the same downstream port, enabling embedded USB 3.x peripherals alongside legacy USB 2.0 devices without external muxes. Driver compatibility covers Microsoft Windows 10/8/7/XP, Apple OS X 10.4+, and mainstream Linux hub drivers, removing the need for custom host stacks.
Typical applications include USB-C docking stations, multi-port USB hubs, monitors with integrated USB expansion, embedded industrial USB fan-out, and Type-C breakout boards. Choose USB5807CT/KD when a 7-port SS hub with OEM-tunable power/charging profiles is required in a thermally-constrained enclosure.
When designing with this part, ensure adequate copper area under the exposed pad and route SuperSpeed pairs with 90 ohm differential impedance. The host MCU must configure PortSplit, flexPORT, and charging parameters via I2C/SPI before downstream ports enumerate at full capability.

Typical Applications
USB5807CT/KD is suitable for 7 applications: USB-C Docking Station, Multi-Port USB Hub (Standalone), Monitor with Integrated USB Expansion, Industrial Embedded USB Fan-Out, Type-C Breakout / Development Board, Automotive-Grade USB Hub (Reference Design), Medical Device USB Expansion.
USB-C Docking Station
The USB5807CT/KD's 7 downstream SS ports plus integrated USB Type-C MUX make it a natural fit for USB-C docking stations that fan out a single Type-C upstream into multiple SS/HS device connections. Its 5 Gbps SuperSpeed lanes deliver the bandwidth required for external NVMe enclosures, dual 4K display links, and gigabit Ethernet adapters running concurrently. The I2C/SPI host interface lets the docking-station MCU configure per-port charging profiles (BC 1.2, Apple, divider modes) via MultiTRAK and flexPORT registers. PortSplit enables simultaneous USB 3.x and USB 2.0 signaling on the same port, useful for legacy keyboards or mice plugged into SS-capable downstream ports. Commercial 0C to +70C operation covers office and home environments.
Recommended
Multi-Port USB Hub (Standalone)
The USB5807CT/KD delivers exactly the 7-port count required for high-density desktop USB hubs that need to support a mix of SS peripherals and HS/FS legacy devices. Its 5 Gbps SuperSpeed PHYs handle external SSDs and high-resolution webcams without throughput bottlenecks, while integrated USB 2.0 transceivers maintain backward compatibility with mice, keyboards, and printers. PortSplit and flexPORT allow per-port tuning of signal emphasis and equalization, which compensates for cable losses in long-reach downstream runs. The 100-VQFN (12x12 mm) package fits easily inside compact hub enclosures, and exposed-pad thermal dissipation keeps junction temperatures low even with all 7 ports active.
Recommended
Monitor with Integrated USB Expansion
Modern monitors integrate USB hubs that drive upstream Type-C alt-mode plus downstream SS ports for keyboard, mouse, webcam, and headset connections. The USB5807CT/KD's 7 ports support 4 downstream SS lanes for high-bandwidth devices plus 3 HS/FS lanes for HID peripherals, all sharing one upstream SS link to the host PC. The integrated USB Type-C MUX removes the need for an external CC-logic chip, reducing BOM cost. MultiTRAK technology dynamically optimizes power delivery per port, allowing the monitor to advertise higher charging currents without exceeding the upstream Type-C contract. The commercial 0C to +70C temperature range covers desktop and conference-room deployments.
Recommended
Industrial Embedded USB Fan-Out
In industrial PCs, factory controllers, and test rigs, the USB5807CT/KD provides 7-port USB expansion inside a thermally-constrained enclosure while supporting both legacy USB 2.0 industrial I/O modules and modern SS cameras or data loggers. The VQFN-100 package's exposed pad simplifies chassis-grounded heatsinking, and MultiTRAK's per-port power management helps meet industrial EMC and surge requirements. PortSplit lets embedded USB 3.x vision modules coexist with USB 2.0 sensor interfaces on the same hub without contention. The I2C host interface allows a supervisory controller to monitor and reset individual ports on fault events. Industrial -40C variant (USB5807CT-I/KD) extends deployment to factory floors.
Recommended
Type-C Breakout / Development Board
The USB5807CT/KD is widely used on Type-C breakout boards that expose 7 SS/HS ports plus power-delivery negotiation to developers and prototype builders. Its USB-IF TID1595 compliance ensures that test equipment and host systems enumerate the breakout without driver issues on Windows, macOS, and Linux. The integrated Type-C MUX simplifies board layout by eliminating external crossbar switches, while flexPORT registers let developers tune each port's behavior via on-board I2C EEPROM. The 100-VQFN footprint is supported by Microchip's USB5807 evaluation board reference schematics, accelerating prototype bring-up.
Recommended
Automotive-Grade USB Hub (Reference Design)
Although USB5807CT/KD is the commercial-temperature variant, it serves as a reference design starting point for automotive USB hubs in head units, charging trays, and rear-seat entertainment modules. The 7-port count supports multiple passenger connections plus dedicated infotainment links, while MultiTRAK's per-port current limiting aligns with automotive USB-charging requirements. Engineers targeting AEC-Q100 qualification should validate against the Microchip automotive-grade USB portfolio or use USB5807CT-I/KD with additional component derating. The VQFN-100 package is compatible with typical automotive PCB stack-ups and conformal-coating processes used by OEM Tier-1 suppliers.
Recommended
Medical Device USB Expansion
Medical imaging carts, patient monitors, and diagnostic instruments require multi-port USB hubs to connect ultrasound probes, barcode scanners, RFID readers, and touchscreen overlays simultaneously. The USB5807CT/KD's 7 ports support these mixed-bandwidth devices, and its driver compatibility across Windows 10/8/7/XP, macOS 10.4+, and Linux reduces the burden of medical-platform certification. PortSplit ensures that USB 3.x imaging devices can run at full bandwidth without starving USB 2.0 HID peripherals. The I2C host interface lets the medical device's safety controller monitor per-port VBUS current and isolate faults. Commercial-grade MTBF is sufficient for non-life-support medical peripherals; mission-critical applications should review IEC 60601-1 isolation requirements separately.

Design Notes
The 100-VQFN package has an exposed thermal pad that MUST be soldered to a continuous ground plane with at least 8 thermal vias (0.3 mm drill, 0.5 mm pitch) to the inner ground layer. Route all SuperSpeed differential pairs at 90 ohm differential impedance with intra-pair skew under 50 mil, and maintain at least 3W spacing from HS/FS pairs to minimize crosstalk. Keep the 1.08 V and 3.3 V decoupling capacitors within 2 mm of their respective supply pins; Microchip recommends a 4.7 uF bulk plus 0.1 uF per-pin decoupling network.
USB5807CT/KD requires two supply rails - 1.08 V for the digital core and 3.3 V for I/O and PHYs - both of which must ramp monotonically before the upstream VBUS. Use a TPS62177 or similar buck converter with at least 600 mA headroom on the 3.3 V rail for SS PHY bias currents. Per-port VBUS current limiting is configured via the MultiTRAK registers; default 900 mA per port is suitable for BC 1.2 charging, but Apple 2.4 A mode requires explicit firmware configuration via the I2C/SPI host interface.
SuperSpeed TX de-emphasis and RX equalization are tunable per-port through the flexPORT registers accessed via SPI. For long-cable downstream runs (>2 m), increase TX de-emphasis by 2-3 dB and enable RX adaptive equalization; for short captive cables (<0.5 m), use the default settings. PortSplit must be configured before the host enumerates the hub; otherwise downstream USB 3.x devices will fail to link-train. Per the Microchip datasheet, PortSplit is enabled by writing the Port Split Configuration register (offset 0x4EEC) to the desired mode.
Common bring-up failures include: (1) leaving the SPI/I2C host MCU's firmware in reset while the hub enumerates, causing configuration to be skipped; (2) forgetting the 32.768 kHz reference clock on the XTAL pins, which prevents SS link-training; (3) routing SuperSpeed pairs over a power-plane split, causing impedance discontinuities and eye-diagram failures. Use the Microchip USB5807 evaluation board as a known-good reference and probe the REFCLK pin during initial bring-up to confirm the crystal is oscillating.
Compliance Information
