Product details
Overview
TPS25740RGER from Texas Instruments is a USB Type-C™ and USB Power Delivery 2.0 certified source controller in a 24-pin VQFN (4.0 mm × 4.0 mm) package. It implements a PD-compliant power source with pin-selectable voltage advertisement (5 V, 12 V, 20 V), peak power configuration (15 W–100 W), and integrated gate driver for external N-channel MOSFETs. It monitors CC1/CC2 to detect sink attachment, controls VBUS enablement, and manages VBUS discharge per USB PD spec - deployed in wall adapters, power banks, and cigarette lighter adaptors.
For engineers reviewing the TPS25740RGER datasheet, TPS25740RGER pinout, TPS25740RGER application, or TPS25740RGER equivalent, key selection considerations include its 4.65 V–25 V wide input range, <10 µA quiescent current in unattached state, built-in 1.85 V/35 mA DVDD rail, IEC 61000-4-2 ±8 kV contact ESD protection on CC pins, and support for up to three programmable PDOs without firmware.
Technical Context
The TPS25740RGER operates as a hardware-configured USB PD source controller - no microcontroller or firmware required. Its control logic uses four digital inputs (PSEL, HIPWR, PCTRL, EN12V) to set advertised voltages and power levels, while CTL1/CTL2 drive external DC/DC regulators to match negotiated PD contracts. The device integrates analog comparators for VBUS monitoring (4.45 V rising threshold), ISNS-based overcurrent detection (22.6 mV trip), and die temperature sensing (135 °C OTSD trigger).
It features dual open-drain gate drivers (GDNG/GDNS) capable of driving high-side NMOS switches, a dedicated VBUS discharge output (DSCG), and robust safety architecture including fast/slow OVP, UVP, OTP, and fault-initiated shutdown via GD pin. All CC-line signaling complies with USB PD 2.0 physical layer timing (3.3 µs bit interval, 300–600 ns edge rates).

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 |
|---|---|---|---|
| TPS25740ARGER | Supports 5 V/9 V/15 V PDOs only; lower max power (81 W); different EN9V pin function vs EN12V | Targeted at 9 V/15 V markets (e.g., consumer chargers), not 12 V/20 V industrial or laptop adapters | Select TPS25740ARGER only if 9 V/15 V compliance suffices and 20 V operation is unnecessary. |
| STUSB4500QTR | Requires external MCU for PD messaging; lacks integrated gate drivers and DVDD rail; smaller 20-pin QFN | Suitable for designs already using host MCU; not viable for standalone, firmware-free implementations | Choose STUSB4500QTR only when existing MCU resources are available and hardware-only solution is not required. |
Compared with TPS25740RGER, the TPS25740ARGER offers reduced voltage flexibility but identical pinout and feature set otherwise, while the STUSB4500QTR shifts PD protocol handling to firmware - increasing BOM cost and development effort but enabling custom PD extensions.

FAQ
What is the primary function of the TPS25740RGER in a USB-C power delivery system?
The TPS25740RGER serves as a standalone USB Power Delivery 2.0 certified source controller. It detects USB-C sink attachment via CC1/CC2, advertises configurable power data objects (5 V/12 V/20 V), negotiates contracts, enables VBUS through external NMOS FETs driven by GDNG/GDNS, and manages VBUS discharge - all without firmware. In the TPS25740RGER, this is implemented using hardware pin strapping, making it ideal for cost-optimized, production-ready USB-C adapters.
Does the TPS25740RGER require an external microcontroller to operate?
No, the TPS25740RGER does not require an external microcontroller. Its entire USB PD 2.0 source functionality - including CC-line detection, PDO advertisement, contract negotiation, VBUS enablement, and discharge control - is implemented in hardware. Configuration is performed via four digital inputs (PSEL, HIPWR, PCTRL, EN12V), eliminating firmware development, flash memory, and associated qualification overhead. This makes the TPS25740RGER uniquely suited for rapid certification and high-volume manufacturing of USB-C power adapters.
What is the purpose of the UFP pin on the TPS25740RGER?
The UFP (Upstream Fault/Port) pin on the TPS25740RGER is an open-drain output that asserts low when either CC1 or CC2 is pulled down by a USB-C sink - indicating valid port attachment. This signal can be used to enable upstream power stages (e.g., turn on AC/DC converter or boost regulator), thereby reducing system standby power. In the TPS25740RGER, UFP remains inactive during sleep mode and transitions only upon confirmed sink detection, supporting ultra-low-quiescent-current designs like portable power banks.
How does the TPS25740RGER handle overvoltage and overcurrent protection?
The TPS25740RGER implements dual-stage overvoltage protection (fast OVP at 6.05 V for 5 V contracts, 13.75 V for 12 V, 23.05 V for 20 V; slow OVP with hysteresis) and ISNS-based overcurrent detection with 22.6 mV trip threshold (configurable to 34 mV for 5 A). Upon fault, it disables GDNG/GDNS gate drivers, asserts DSCG to discharge VBUS, and holds shutdown until reset. These protections are fully hardware-based and active across all operating modes - including during voltage transitions - ensuring compliance with USB PD safety requirements without software intervention.
Can the TPS25740RGER support both 12 V and 20 V output simultaneously?
No, the TPS25740RGER supports only one active PDO at a time - it selects and regulates a single output voltage (5 V, 12 V, or 20 V) based on the negotiated USB PD contract. However, its CTL1 and CTL2 outputs provide parallel digital signals to control external DC/DC regulators, enabling system-level implementation of multi-rail architectures. For example, a design may use CTL1/CTL2 to switch between 12 V and 20 V regulator enable lines - but the TPS25740RGER itself sources only one voltage per active connection.
