Product details
Overview
TPS25750DRJKR from Texas Instruments is a standalone USB Type-C® and Power Delivery (PD) 3.0 controller with integrated 5-V/3-A sourcing switch and 28-V/7-A bi-directional high-voltage power switch, designed for DRP (dual-role port) applications in power banks and industrial USB-C PD systems. It delivers full physical layer + policy engine functionality, BC1.2 charging support, and robust 26-V-tolerant CC pin protection.
For engineers reviewing the TPS25750DRJKR datasheet, TPS25750DRJKR pinout, TPS25750DRJKR application, or TPS25750DRJKR equivalent, key selection criteria include integrated HV bi-directional switching capability, I²C master/slave interface for battery charger control, web-based GUI configuration, thermal performance under 7-A PPHV load, and QFN-38 RJK package compatibility with 4.0 mm × 6.0 mm PCB footprint.
Technical Context
The TPS25750DRJKR implements a complete USB PD 3.0 stack including cable orientation detection, VCONN switching, and dual-role port negotiation without external firmware. Its integrated PP_5V (36 mΩ, 3 A) and PPHV (16 mΩ, 7 A) power switches operate with independent overvoltage, undervoltage, reverse-current, and slew-rate-controlled protection logic.
It features dual I²C interfaces - master (for TI BQ battery chargers) and slave (for host MCU coordination) - plus 10 configurable GPIOs, 3.3-V LDO output for dead-battery operation, and ADC inputs for system-level voltage monitoring. All CC pin circuitry is rated to 26 V for interoperability with non-compliant sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65987D | Higher integration: includes integrated DC/DC converters and more GPIOs; requires external firmware; larger 40-pin QFN package. | Targeted at host-side applications (laptops, docks) requiring complex power routing and multiple VBUS domains. | Choose TPS65987D when system needs multi-rail DC/DC conversion and advanced policy engine customization; TPS25750DRJKR suits cost-sensitive, firmware-free DRP endpoints. |
| STUSB4500 | No integrated power switches; relies on external MOSFETs for power path; supports PD 3.0 but lacks I²C master interface for battery chargers. | Better suited for low-power sink-only applications where external FET control is acceptable and BQ charger integration is not required. | Choose STUSB4500 for ultra-low-power USB-C accessories; TPS25750DRJKR is preferred when integrated 7-A bi-directional switching and TI charger synergy are critical. |
Compared with TPS65987D and STUSB4500, the TPS25750DRJKR uniquely combines firmware-free PD operation, integrated 7-A bi-directional switching, and dedicated I²C master support for TI battery chargers - making it optimal for self-contained, high-current DRP endpoints like power banks and industrial chargers.

FAQ
What USB Power Delivery version does the TPS25750DRJKR support?
The TPS25750DRJKR supports USB PD 3.0 and full USB Type-C specification compliance, including fast role swap, structured vendor-defined messages (VDMs), and programmable power supply (PPS) readiness. It implements both physical layer and policy engine functions on-die, enabling full DRP negotiation without external firmware. The TPS25750DRJKR also supports BC1.2 charging protocols for backward compatibility with legacy USB-A devices.
Does the TPS25750DRJKR require external firmware development?
No, the TPS25750DRJKR is a standalone USB PD controller with embedded firmware - no external microcontroller or code development is needed. Configuration is performed via a web-based GUI that generates a custom image based on application requirements. The TPS25750DRJKR handles all USB-C attachment detection, orientation sensing, PD messaging, and power path control autonomously, significantly reducing time-to-market for USB-C PD designs.
What is the maximum continuous current supported by the TPS25750DRJKR's integrated power switches?
TPS25750DRJKR integrates two independent power switches: the PP5V switch supports up to 3 A continuously (36 mΩ RDS(on)), and the PPHV switch supports up to 7 A continuously (16 mΩ RDS(on)) in sink or source direction. Thermal performance is validated per JEDEC JESD51-7 with RθJB = 21.1°C/W, enabling sustained 7-A operation on standard 2-layer PCBs with adequate copper pour under 85°C ambient conditions.
How does the TPS25750DRJKR handle reverse current protection on its high-voltage path?
The TPS25750DRJKR provides hardware-based reverse current protection (RCP) on the PPHV path with programmable threshold settings (2–16 mV) and sub-microsecond response time (<0.7 µs). It monitors VPPHV – VVBUS in real time and disables the internal FET within 400–1000 µs upon detection. This RCP logic operates independently of firmware and remains active during all operational modes, including sleep and modern standby - ensuring safety for battery-backed or multi-rail USB-C systems using the TPS25750DRJKR.
Can the TPS25750DRJKR interface directly with TI battery charger ICs?
Yes, the TPS25750DRJKR includes a dedicated I²C master interface (I2Cm_SDA/I2Cm_SCL) designed specifically to control TI BQ-series battery chargers such as the BQ25792 and BQ25710. This interface supports clock stretching, multi-byte transfers, and interrupt signaling via I2Cm_IRQ, enabling precise charger configuration, telemetry readback, and fault coordination - all without requiring an external MCU. This tight integration is a core differentiator of the TPS25750DRJKR in portable PD-powered systems.
