TPS25810RVCT - 3A USB-C Power Switch | Texas Instruments
MPN: TPS25810RVCT ✓ Hoạt độngTPS25810RVCT Tóm tắt
A USB Type-C Downstream Facing Port controller is a power-management interface IC that manages the Configuration Channel, or CC, pins of a USB Type-C receptacle and controls the delivery of VBUS. In the hierarchy of electronic components, the TPS25810RVCT is a USB interface controller, Type-C port controller, power-management IC, and semiconductor. Unlike a standalone USB power switch, it combines source-port policy and load detection with an integrated current-rated switching path.
The principal feature is the integrated 3 A USB power switch. The device also includes VCONN support for systems that must supply power through the Type-C cable to an active cable or accessory. Load detection provides a mechanism for evaluating the attached load before or during power delivery. The RVC package includes 20 pins and occupies only 3 mm by 4 mm of board area, supporting compact USB-C power-accessory designs.
The TPS25810 family is intended for equipment that presents a USB Type-C source port rather than a sink port. According to the verified Texas Instruments product information, it monitors the Type-C Configuration Channel lines, detects an attached Upstream Facing Port device, applies power to VBUS, and communicates the selectable VBUS current-sourcing capability over CC. These functions place attachment detection, source-current negotiation, and power-path control in one device.
Typical uses include USB-C docking accessories, compact power adapters, laptop chargers, and other equipment requiring a Type-C Downstream Facing Port. A documented TI reference design, PMP11594, uses the TPS25810 with the LMR14030 in a 5 V, 3 A charger reference design. This demonstrates that the controller can be combined with a step-down regulator to provide a regulated downstream bus.
Designers should verify the complete Type-C source-port power path, including the external components, connector limits, CC pull-up behavior, thermal conditions, and advertised current level. The datasheet remains the controlling source for pin functions, timing, current limits, and capacitor recommendations because those details were not included in the supplied search extracts.
This product page consolidates verified manufacturer and distributor information, package and temperature data, documented reference-design usage, drop-in replacement evidence, and application guidance. It also distinguishes confirmed characteristics from parameters that still require confirmation from the full Texas Instruments TPS25810 datasheet.

Ứng dụng tiêu biểu
TPS25810RVCT phù hợp cho 6 Áp dụngs: USB-C Docking Power Accessory, 5 V 3 A USB-C Charger, Compact USB-C Power Supply, USB-C Laptop Charging Accessory, Powered USB-C Cable Accessory, Industrial USB-C Power Module.
USB-C Docking Power Accessory
The TPS25810RVCT fits a USB-C docking accessory that must present a Type-C Downstream Facing Port and safely deliver VBUS power. Its integrated 3 A power switch, VCONN support, and load detection provide the core functions required when an accessory supplies bus power to a connected USB-C device. According to the verified Texas Instruments product information, the controller monitors the Configuration Channel lines, detects the attached device, and communicates the selectable source-current capability. Placing it in the accessory's source path reduces the need for separate Type-C policy logic. The 20-pin 3 mm by 4 mm RVC package also supports compact designs, although the final layout must follow the manufacturer pin and thermal guidance.

5 V 3 A USB-C Charger
The TPS25810RVCT is suited to a 5 V, 3 A USB-C charger because Texas Instruments documents the TPS25810 in the PMP11594 low-cost 5 V, 3 A charger reference design. The controller manages the Type-C source side, including Configuration Channel monitoring, VBUS application, selectable source-current advertisement, VCONN, and load detection, while the LMR14030 performs the associated step-down conversion. This division of responsibilities supports a compact source-port design. The reference-design association provides a practical starting point, but production engineers should still verify current limits, connector behavior, protection, thermal performance, and required external components against the current datasheets.
Được đề xuất
Compact USB-C Power Supply
The TPS25810RVCT is appropriate for compact USB-C power supplies where the receptacle is a source rather than a sink. Its 3 A integrated power switch and source-controller functions are intended to control VBUS after the attached Upstream Facing Port device is detected. The 20-pin RVC package occupies 3 mm by 4 mm, helping reduce board area in adapters and compact peripherals. Texas Instruments also identifies use of the controller with a step-down regulator and describes BC1.2-compatible behavior in the PMP11594 reference-design context. Designers should treat the verified 3 A switch rating as a device specification while separately checking the connector, cable, trace widths, and downstream load limits.

USB-C Laptop Charging Accessory
The TPS25810RVCT can be used in a USB-C laptop-charging accessory that needs controlled Type-C source-current advertisement and load detection. The device's CC monitoring allows it to identify an attached source-capable load before applying VBUS, while the integrated 3 A switch provides the controlled power path. The verified manufacturer information confirms the source-port role and the availability of selectable VBUS current capability. This makes the controller relevant to multi-level USB-C power accessories and compact PD-era equipment that presents a Downstream Facing Port. A complete implementation must still validate the advertised current level, cable-current derating, connector mechanical rating, fault response, and thermal performance using the full manufacturer documentation.

Powered USB-C Cable Accessory
The TPS25810RVCT is relevant to powered USB-C cable accessories because VCONN support is explicitly identified in the verified product description. In a cable that requires auxiliary power, VCONN can supply power beyond the principal VBUS path while the controller manages Type-C attachment and source behavior. The 3 A integrated switch and load-detection functions provide additional source-port control in the accessory's power architecture. The 20-pin 3 mm by 4 mm package can accommodate the controller where connector density is important. Exact VCONN limits, activation behavior, timing, and external network requirements were not included in the supplied excerpts and must be confirmed from the official datasheet before schematic release.
Được đề xuất
Industrial USB-C Power Module
The TPS25810RVCT can serve as the Type-C source-management element in an industrial USB-C power module. Its -40 °C to +125 °C specified operating-temperature range supports consideration across a broad range of equipment environments, while integrated VBUS switching, VCONN, CC monitoring, and load detection consolidate several source-port functions. The compact RVC package may be useful where modules have limited connector and routing space. However, the broad temperature rating alone does not establish suitability for a specific industrial grade. Designers should verify operating-temperature derating, electrical transient tolerance, regulatory requirements, fault behavior, and long-term availability using the full datasheet and TI quality documentation.

Ghi chú thiết kế
Design the VBUS power path around the verified 3 A integrated switch rating, but do not assume that the USB-C connector, cable, PCB traces, or attached load can each sustain 3 A. Confirm current-advertisement limits, thermal derating, and connector requirements from the full TPS25810 datasheet. Use the TI PMP11594 reference design as the starting point for a practical 5 V, 3 A charger architecture.
Place the TPS25810RVCT and its required external components close to the USB-C connector and VBUS power path. Keep high-current VBUS and VCONN routing short and sufficiently wide, while maintaining the layout separation and return-current paths required by the official datasheet. The exact CC and power-path geometry was not present in the supplied extracts, so the manufacturer PCB-layout guidance should take precedence over general placement assumptions.
Do not treat a USB power switch with a similar function as a drop-in replacement without verifying the complete RVC pinout, exposed-pad connection, CC timing, VCONN behavior, load-detection logic, and operating limits. The TPS25810 source-port IC controls both power delivery and Type-C communication, so an apparently similar footprint can still require schematic or firmware changes. Use the official TPS25810 and candidate-device datasheets for every redesign.
Evaluate switch dissipation across the minimum and maximum VBUS voltage and the advertised load current. Estimated: P equals VBUS multiplied by I multiplied by the switch on-resistance; because the supplied data does not provide the on-resistance, a numerical thermal result cannot be calculated reliably. Confirm the operating-resistance curve, exposed-pad solder pattern, thermal resistance, and maximum junction temperature from the full datasheet before selecting copper area or cooling provisions.
