TS3USB3000MRSER Overview
A USB switch IC is a special-purpose analog multiplexer that routes high-speed differential signals between a single downstream port and two upstream paths (host vs. MHL sink). In the hierarchy of power management and signal routing components, this part belongs to the USB interface IC category, sitting between the connector and the application processor. DPDT switches such as the TS3USB3000 are critical because they must pass 480 Mbps USB signals and up to 3 GHz MHL content with minimal insertion loss, low crosstalk, and high off-isolation.
Key features of the TS3USB3000 include low on-resistance (Ron) on the USB data paths, low on-capacitance (Con) for high-bandwidth signal transmission, 1.8-V-compatible select pins for direct GPIO control from a mobile processor, and a quiescent current of approximately 5 uA. The wide supply range (2.3 V to 4.8 V) covers both 3.3 V system rails and the typical 3.8 V Li-ion battery range without additional regulation. The small 1.5 mm × 2 mm UQFN footprint makes it ideal for space-constrained mobile applications.
The TS3USB3000 uses a charge-pump-less architecture with simple CMOS logic-level select inputs. The two select pins (S1 and S0 per TI documentation) determine whether the common port is routed to the USB path or the MHL path. Internal ESD protection on the signal pins improves robustness against connector-level transients, which is critical for hot-plug consumer electronics.
Typical applications include smartphones and tablets with MHL-enabled video output, automotive infotainment systems that mirror mobile content via USB or MHL, portable media players, and USB/MHL dongles. The wide bandwidth also makes it suitable for any system needing to multiplex two high-speed differential pairs onto a single connector.
When designing with this part, place the device as close as possible to the USB/MHL connector to minimize stub lengths and signal-integrity degradation. Use controlled-impedance differential routing (90 ohm) on both sides of the switch, and provide adequate ground stitching vias along the signal path to maintain return-current continuity.

Typical Applications
TS3USB3000MRSER is suitable for 6 applications: Smartphone USB / MHL Multiplexing, Tablet and Mobile Media Player Dock Interface, Automotive Infotainment with MHL Input, USB / MHL Dongle and Adapter Cables, Industrial Handheld Terminals, Digital Camera and Camcorder USB/HDMI Output.
Smartphone USB / MHL Multiplexing
The TS3USB3000MRSER is purpose-built to share a single Micro-USB connector between USB 2.0 High-Speed data and MHL video output in smartphones. Its 6.1 GHz -3 dB bandwidth on the MHL path easily passes the MHL signal bandwidth, while the USB path supports 480 Mbps High-Speed operation with low on-resistance and minimal insertion loss. The 1.5 mm x 2.0 mm UQFN-10 package fits beneath the connector on the main board, and the 1.8 V-compatible select pins connect directly to the application processor GPIO without level translation. Quiescent current of just 5 uA preserves battery life during standby, making the part a standard choice in phones that supported MHL output.

Tablet and Mobile Media Player Dock Interface
Tablets and portable media players that expose MHL output via a Micro-USB connector use the TS3USB3000MRSER to switch between USB data mode and MHL video mode when the device is docked. The wide 2.3 V to 4.8 V supply range covers the direct Li-ion battery voltage as well as a regulated 3.3 V rail, allowing flexible power-tree design. The DPDT topology supports both differential pairs simultaneously, so one device handles USB D+/D- and the other handles the MHL differential pair. Internal ESD protection on the signal pins protects the downstream processor from connector-level transients during hot-plug events, a real concern on consumer docking accessories.
Recommended
Automotive Infotainment with MHL Input
Automotive head units that accept MHL input from a connected smartphone or tablet rely on the TS3USB3000MRSER to switch between a USB debug/data path and the MHL video path. The -40 C to +85 C operating temperature range covers the full automotive infotainment temperature spec, and the small UQFN-10 package eases layout behind the head-unit display connector. Differential routing with controlled 90 ohm impedance on both sides of the switch keeps the MHL eye diagram clean up to its 3 GHz fundamental. Low on-resistance preserves the USB 2.0 High-Speed signal integrity required for media file transfers.
Recommended
USB / MHL Dongle and Adapter Cables
Passive and active MHL-to-HDMI dongles, as well as Micro-USB-to-HDMI adapter cables, embed the TS3USB3000MRSER inside the dongle housing to handle the mode-switching between charging and video output. The tiny 1.5 mm x 2.0 mm package fits inside the dongle plastic without forcing a redesign of the connector shell. The wide supply tolerance means the dongle can be powered from the 5 V VBUS line directly or from a small internal LDO. The combined USB + MHL switch function eliminates the need for two separate MUX ICs, reducing BOM cost and PCB area in space-constrained adapter housings.
Recommended
Industrial Handheld Terminals
Ruggedized industrial handhelds (barcode scanners, field service tablets) often include MHL output for diagnostics display mirroring while also requiring USB data exchange for firmware updates. The TS3USB3000MRSER allows a single ruggedized Micro-USB port to serve both functions, reducing mechanical connector count - a key reliability improvement in drop-prone industrial environments. The extended -40 C to +85 C temperature range handles outdoor and warehouse environments, and the 5 uA quiescent current is small enough to ignore in battery-life calculations for handheld terminals that sit on the charger most of the time. The integrated ESD protection simplifies the ruggedized enclosure design.
Recommended
Digital Camera and Camcorder USB/HDMI Output
Digital cameras and camcorders that output both USB data (for file transfer) and HDMI/MHL video (for playback on a TV) use the TS3USB3000MRSER to multiplex these signals through a single Micro-USB port. The 6.1 GHz MHL bandwidth supports clean 1080p video transport without visible artifacts, while the low-con USB path preserves USB 2.0 High-Speed eye margins for fast file offload. The 1.8 V select pin compatibility matches the camera's image-processor GPIO levels directly. The compact UQFN-10 footprint allows placement adjacent to the I/O connector on the camera's small main board, keeping differential traces short and matched.

Design Notes
Place the TS3USB3000MRSER as close as physically possible to the Micro-USB connector - within 5 mm is ideal. The high-speed USB (480 Mbps) and MHL (multi-GHz) differential signals are extremely sensitive to stub length and impedance discontinuities. Use controlled-impedance 90 ohm differential routing on both sides of the switch, and add ground-stitching vias along the differential pairs to maintain return-current continuity. Avoid routing any other signals beneath or near the UQFN-10 exposed pad (EP), which must be soldered to the ground plane for both thermal dissipation and electrical reference.
Decouple VCC (pin 5) with a 0.1 uF X7R ceramic capacitor placed within 2 mm of the pin. A bulk 1 uF capacitor on the same rail provides additional margin for the 5 uA quiescent current transients during switching. The 2.3 V to 4.8 V supply range allows direct connection to a Li-ion battery (3.0 V to 4.2 V) without an LDO, but a clean regulated rail is preferred to minimize coupling of battery noise into the high-speed MHL path.
Maintain 90 ohm differential impedance on USB D+/D- and on the MHL differential pair. Keep the two pairs length-matched within 150 mil to avoid skew-induced eye closure. The TS3USB3000MRSER's 6.1 GHz -3 dB bandwidth supports clean MHL eye diagrams at typical 1080p60 rates, but the PCB channel loss between the switch and the connector must be minimized to preserve margin. Place the switch on the same layer as the connector escape, with no vias in the high-speed path if possible.
Do not leave the exposed pad (pin 10) floating - it must be soldered to a grounded copper pad for both thermal and electrical reasons. Do not assume the M suffix in MRSER indicates a silicon variant; per TI E2E support, the M suffix only denotes tape-and-reel orientation, and MRSER/RSER are electrically identical. Finally, avoid driving the select pins (S0, S1) with voltages above VCC, or the internal ESD clamp structures may conduct and inject noise into the switch core.
