TPS26750ASRSMR 개요
A USB Type-C PD controller is an interface and power-management IC that manages CC-line communication, cable attach/detach detection, power-role swapping, and PD message negotiation between two USB-C devices. Within the system hierarchy, it sits between the physical USB-C connector and the DC-DC conversion stage, acting as the protocol brain that tells the power stage what voltage and current to deliver. It belongs to the broader categories of USB interface ICs, power management ICs, and specialized power PMICs.
Key features include USB PD 3.2 compliance with 240W Extended Power Range support, integrated power switches that reduce external BOM count, dual-role port operation allowing the device to act as either power source or sink, and standalone operation that removes the need for an external MCU in many designs. The high integration level simplifies layout and shortens design cycles for high-power USB-C endpoints.
Technically, the TPS26750A handles EPR negotiation up to 48V, managing CC-line BMC and Biphase Mark Coding signaling per the USB PD 3.2 specification. The integrated switches handle VBUS path control, and the controller supports firmware updating so OEMs can adapt PD behavior in the field. According to the TI product page, the device is described as a highly integrated standalone controller optimized for EPR DRP power applications.
Typical applications include laptop and notebook chargers, power bricks and adapters, docks and monitors, and high-power USB-C sink devices such as monitors and eGPU enclosures. Any system moving up from 100W SPR designs to 240W EPR designs benefits from this controller class.
A key design consideration is that EPR operation at 48V/5A demands careful VBUS trace spacing, connector EPR-capable rating, and thermal validation of the integrated power path; SPR-only designs can consider the TPS26750SRSMR variant instead.

일반적인 애플리케이션
TPS26750ASRSMR 적합 용도: 6 애플리케이션s: 240W Laptop Chargers and Power Adapters, USB-C Docks and Monitors, Notebook and Tablet Sink Power Input, Multi-Port Desktop Charging Stations, Industrial and Test Instrument USB-C Power, Automotive and Ruggedized USB-C Charging.
240W Laptop Chargers and Power Adapters
The TPS26750ASRSMR is purpose-built for USB-C PD 3.2 wall adapters and laptop chargers operating at Extended Power Range levels up to 240W (48V/5A). Its integrated power switches handle the VBUS path without external FETs, and its standalone operation removes the need for a host MCU, reducing BOM and firmware complexity. Because TI explicitly positions the A-variant for EPR DRP power applications, it natively negotiates EPR sink/source messages on the CC line. Place it between the USB-C connector and a wide-VIN DC-DC stage; the controller reports negotiated voltage to the converter via GPIO/I2C. Thermal design must account for switch losses at 5A, and an EPR-rated connector is mandatory for compliance.

USB-C Docks and Monitors
Monitors and docking stations must act as power sinks (receiving up to 240W from a laptop adapter) while simultaneously acting as sources for downstream peripheral ports - exactly the dual-role-port behavior the TPS26750ASRSMR provides. Its PD 3.2 EPR support allows a monitor to accept 48V input over a single USB-C cable, and integrated switches protect against reverse-current and fault events on the VBUS path. Standalone firmware handles role swaps, cable detection, and PD message handling without burdening the system main SoC. Design consideration: EPR sink operation requires periodic EPR keep-alive messaging and a VBUS discharge path, both supported by the controller per TI's EPR DRP positioning.

Notebook and Tablet Sink Power Input
In laptops, tablets, and other battery-powered host devices, the TPS26750ASRSMR manages the USB-C power input path, negotiating the highest safe voltage (up to EPR 48V) from the attached adapter and enabling the charger front end accordingly. DRP capability lets the same port later act as a source to charge accessories, a common ultrabook feature. Integrated power switches simplify the compact layouts typical of thin notebooks, and TI's EPR DRP optimization ensures reliable EPR capability discovery and keep-alive handling with 240W adapters. The controller's standalone mode offloads PD messaging from the embedded controller, and firmware updatability allows field adaptation as the USB PD 3.2 ecosystem matures.

Multi-Port Desktop Charging Stations
Desktop chargers with four or more USB-C ports must arbitrate total power budget across ports while each port independently negotiates its own PD contract. The TPS26750ASRSMR suits the 140-240W master port (EPR-capable), and the same-footprint TPS26750SRSMR can serve SPR-only secondary ports, giving a common PCB layout across the board. Standalone operation means each port runs its PD stack autonomously; a host MCU coordinates the power-shifting policy over I2C. Integrated switches provide per-port fault isolation, important for safety certification. Thermal note: at a 240W port running 48V/5A, verify connector and PCB copper sizing per USB-C EPR current-rating requirements.

Industrial and Test Instrument USB-C Power
Industrial instruments and bench equipment increasingly adopt USB-C as both a data and power interface. The TPS26750ASRSMR provides EPR-capable sink and source roles so a bench instrument can draw up to 240W from a USB-C PD adapter or power a DUT under test. The robust PD 3.2 state machine handles the cable-swap and hard-reset events common on lab benches, and integrated switches simplify protection design where field conditions are unpredictable. Standalone firmware operation keeps the instrument's main processor free for measurement tasks. For instruments limited to 100W (20V) operation, the pin-compatible TPS26750SRSMR variant reduces PD certification scope while preserving the PCB footprint.

Automotive and Ruggedized USB-C Charging
In-vehicle USB-C charging hubs benefit from the TPS26750ASRSMR's high-power source capability, delivering up to 240W to EPR-compatible phones and laptops from the vehicle battery rail via a wide-input buck converter. The integrated VBUS switches provide the fault, short-circuit, and cable-attach protection required in harsh automotive cabin environments, and standalone PD handling avoids loading the body-domain controller with PD protocol tasks. DRP support also enables accessory-facing ports that can receive power for diagnostics. Design consideration: verify the controller's AEC-Q qualification status and the EPR connector's vibration rating against the specific automotive OEM specification before design-in.

주요 차별점
- EPR-optimized firmware positioning for 240W designs (vs TPS26750SRSMR)
- Integrated power switches reduce external BOM (vs TPS26750SRSMR)
- Footprint-identical family for SPR/EPR platform reuse (vs TPS26750SRSMR)
설계 노트
At EPR 240W operation (48V/5A), VBUS routing requires wider trace spacing and an EPR-rated USB-C receptacle; creepage and clearance for 48V must be respected on the PCB, and the integrated power switch thermal path relies on the QFN exposed pad - use a solid via array to an internal ground/power plane. Estimate copper sizing for 5A continuous with at least 2 oz outer copper or heavy internal planes near the VBUS node.
The TPS26750ASRSMR negotiates the PD contract but does not convert power: pair it with a DC-DC converter whose feedback range covers all negotiated PDO voltages up to EPR levels (up to 48V). Use the controller's feedback/I2C signaling to retarget the converter output after each PDO change, and design the converter for the 5A EPR current rating plus margin. Confirm EPR keep-alive timing compliance in firmware per the USB PD 3.2 specification.
Do not assume the A-variant and S-variant are firmware-identical: TI positions the TPS26750A for EPR DRP power applications and the TPS26750 for standard applications, so swapping between TPS26750ASRSMR and TPS26750SRSMR on the same PCB requires reconfiguring and re-certifying firmware with TI's configuration tools. Also verify CC-line ESD protection and the EPR cable requirement - standard SPR-rated cables will fail EPR negotiation, so product documentation must state EPR-capable cable requirements.
