Product details
Overview
TPS25740BRGER from Texas Instruments is a USB Power Delivery 2.0–certified (TID# 1030004) and PD 3.0–compliant source controller for USB Type-C™ applications. It implements full PD negotiation, voltage advertisement (5/9/12/15 V or 5/9/15/20 V), peak power selection (18–100 W), and controls external N-channel MOSFETs via GDNG/GDNS gate drivers. It operates from 4.65 V to 25 V input and draws only 8.5 µA quiescent current when unattached - enabling energy-efficient USB-PD adapters and power banks.
For engineers reviewing the TPS25740BRGER datasheet, TPS25740BRGER pinout, TPS25740BRGER application, or TPS25740BRGER equivalent, this page delivers verified technical context, real-world timing behavior, safety-integrated protection architecture, and validated alternative options for USB Type-C PD source design.
Technical Context
The TPS25740BRGER integrates a complete USB PD 2.0/3.0 source stack with hardware-based protocol engine - eliminating need for firmware or external microcontroller. Its CC1/CC2 transceivers support Rp/Rd detection, PD message transmission (BMC), and VCONN sourcing, while CTL1–CTL3 digital outputs configure external DC/DC regulators per negotiated voltage contract.
Protection is implemented at silicon level: fast OVP (30 µs response), programmable OCP via ISNS, dual-threshold OTSD (TJ1 = 125–145 °C, TJ2 = 140–163 °C), IEC 61000-4-2 ±8 kV contact ESD on CC pins, and active VBUS discharge via open-drain DSCG output. The device supports self-directed port power management in dual-port systems using PCTRL and DVDD signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB PD Compliance | PD 2.0 certified (TID# 1030004); PD 3.0 compliant provider - enables interoperable 5–20 V, up to 100 W sourcing without host MCU. |
| Voltage Advertisement | PIN-selectable: Option 1 = 5/9/12/15 V; Option 2 = 5/9/15/20 V - determines fixed PDO set presented during Source_Capabilities. |
| Peak Power Range | 18 W to 100 W via PSEL pin configuration - sets maximum deliverable power per contract, critical for adapter thermal design. |
| Quiescent Current | 8.5 µA (VPWR = 5 V, no attachment) - meets Energy Star Level VI and EU CoC Tier 2 standby requirements. |
| Gate Driver Outputs | GDNG (open-drain, 12 V max), GDNS (high-side sense) - directly drives N-ch MOSFETs, reducing BOM cost vs. P-ch solutions. |
| VBUS Discharge | DSCG open-drain output with 6.6–10 kΩ bleeder resistance - ensures <1 s VBUS ramp-down after detach per USB Type-C spec. |
| ESD Protection | ±8 kV contact / ±15 kV air-gap on CC1/CC2 per IEC 61000-4-2 - eliminates need for external TVS diodes on CC lines. |
Pinout & Package
TPS25740BRGER is housed in a thermally enhanced 24-pin VQFN package (4.0 mm × 4.0 mm, 0.5 mm pitch) with exposed thermal pad connected to GND/AGND plane for efficient heat dissipation in high-power USB-PD designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD source controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65987D | Requires external MCU for PD policy engine; supports DRP mode and USB data multiplexing; higher integration (integrated LDOs, VCONN, BMC PHY). | Suitable for DRP/DFP+UFP systems needing data tunneling (e.g., docks, monitors); not optimized for cost-sensitive, firmware-free DFP-only adapters. | Select TPS65987D only if DRP capability, USB 2.0/3.1 data switching, or integrated VCONN supply is required - adds complexity and cost over TPS25740BRGER's dedicated source role. |
| STUSB4500 | PD 3.0 compliant but not PD 2.0 certified; supports only 5/9/15/20 V PDOs; no PCTRL pin for dynamic power reduction; lower max power (60 W). | Better suited for mid-power (≤60 W) consumer adapters where certification is secondary to BOM cost; lacks self-directed port management features. | Choose STUSB4500 for cost-driven ≤60 W applications where PD 2.0 certification is not mandatory and dynamic power capping is unnecessary. |
Compared with TPS65987D and STUSB4500, the TPS25740BRGER uniquely delivers USB PD 2.0 certification with zero-firmware operation, N-MOS gate drive, and PCTRL-based dynamic power sharing - making it optimal for high-reliability, low-cost, single-role USB-C power adapters and power banks.

FAQ
What is the USB PD certification status of the TPS25740BRGER?
The TPS25740BRGER is USB PD 2.0 certified with TID# 1030004 and fully compliant with USB PD 3.0 specifications. It implements all mandatory PD 2.0 protocol layers - including BMC physical layer, protocol layer, policy engine, and device policy manager - without external firmware. This certification ensures interoperability with all PD-compliant sinks and eliminates need for third-party protocol validation in end equipment.
Does the TPS25740BRGER require an external microcontroller to operate?
No, the TPS25740BRGER operates autonomously without any external microcontroller or firmware. Its integrated hardware policy engine handles full USB PD negotiation, CC line detection, voltage contract selection, CTLx signaling, and protection responses. Engineers can implement a complete PD source using only passive components, an external DC/DC converter, and N-channel MOSFETs - significantly accelerating development and reducing BOM cost.
How does the TPS25740BRGER manage VBUS discharge after cable removal?
The TPS25740BRGER uses its open-drain DSCG output to actively discharge VBUS through an external resistor. Upon sink detachment, the device asserts DSCG low within 5 ms, enabling the bleeder network to discharge VBUS to below 2.5 V in under 1 second - satisfying USB Type-C specification requirements. The recommended R(DSCG) value depends on maximum VBUS (e.g., 43 Ω for 15 V, 80 Ω for 25 V) and is specified in Section 7.3 of the datasheet.
What protection features are integrated into the TPS25740BRGER?
The TPS25740BRGER integrates overvoltage (fast OVP: 30 µs response), overcurrent (via ISNS pin with 15 µs deglitch), overtemperature (dual-threshold OTSD: TJ1 = 125–145 °C, TJ2 = 140–163 °C), UVLO, and VBUS discharge. It also provides IEC 61000-4-2 ±8 kV contact ESD protection on CC1/CC2 pins - eliminating need for external TVS diodes and enhancing system robustness in real-world environments.
Can the TPS25740BRGER support dual-port power management?
Yes, the TPS25740BRGER supports self-directed port power management in dual-port systems via its PCTRL input pin. When PCTRL is pulled low, the device automatically halves its advertised power capability - enabling dynamic load sharing between two TPS25740BRGER-controlled ports without host MCU intervention. This feature is explicitly documented in the "Self-Directed Port Power Management" section of the datasheet and requires no firmware modification.
