Product details
Overview
FUSB302TV11MPX from onsemi is an AEC-Q100 qualified, automotive-grade USB Type-C controller with integrated BMC Power Delivery 2.0 physical layer, supporting DRP/SRC/SNK roles, 100 W power negotiation, and VCONN switching for full-featured USB 3.1 cables. It operates from −40 °C to +105 °C in a 14-lead WQFN (2.5 mm × 2.5 mm, 0.5 mm pitch) package and targets automotive cigarette lighter adapters and in-vehicle charging systems.
For engineers reviewing the FUSB302TV11MPX datasheet, pinout, applications, or equivalent options, key selection considerations include its automotive temperature rating, autonomous DRP toggle timing (tTOG1 = 45 ms typ, tTOG2 = 30 ms typ), CC current sourcing capability (80/180/330 µA), integrated VCONN OCP (800 mA typ), and I²C Fast Mode Plus support up to 1 MHz.
Technical Context
The FUSB302TV11MPX implements a dedicated BMC PD physical layer with 48-byte TX and 80-byte RX FIFOs, enabling host-controlled PD packet exchange over CC pins. Its dual CCx interface supports orientation detection, attach/detach sensing, and audio/debug accessory mode identification via fixed-threshold comparators and a 6-bit MDAC.
It integrates a programmable CC switch matrix with pull-up (IP), pull-down (RD), and VCONN routing logic - including over-current protection (600–1000 mA) and thermal shutdown (145 °C). Autonomous DRP toggle is implemented via internal timing control (tDIS = 40–160 ms) without processor intervention during unattached state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | −40 °C to +105 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 2. |
| CC Current Levels | 80/180/330 µA - sets VBUS current capability (500 mA / 1.5 A / 3 A) as USB Type-C source per spec. |
| VCONN OCP Limit | 800 mA typical - protects against overcurrent when powering USB 3.1 full-featured cables. |
| DRP Toggle Timing | tTOG1 = 45 ms, tTOG2 = 30 ms - defines SNK-to-SRC and SRC-to-SNK transition intervals in autonomous mode. |
| I²C Speed | Up to 1 MHz - supports Fast Mode Plus for low-latency register access and PD packet handling. |
| PD Receive FIFO | 80 bytes - buffers incoming BMC PD packets including header, data objects, and CRC for host firmware processing. |
| Low-Power Standby | 25 µA typical - enables energy-efficient unattached monitoring with TOGGLE = 1 and wake circuit enabled. |
Pinout & Package
Package: 14-lead WQFN (2.5 mm × 2.5 mm, 0.5 mm pitch), Pb-free, moisture sensitivity level 1 (MSL1).

| VCONN | Power Switch Output | Regulated output switched to CC1 or CC2 to supply VCONN (5 V) to full-featured USB 3.1 cables with OCP and thermal shutdown. |
| VBUS | OVP-Protected Input | Monitors upstream VBUS voltage (4–21 V) for attach/detach detection and PD-level validation; requires external overvoltage protection. |
| VDD | Supply Input | Primary power rail (2.7–5.5 V); powers internal logic, comparators, DAC, and BMC PHY. |
| SCL / SDA | I²C Interface | Standard-compliant I²C bus (Fast Mode Plus, up to 1 MHz) for configuration, status readback, and PD packet exchange. |
| INT_N | Open-Drain Interrupt | Active-low interrupt signaling CC attach/detach, BMC packet arrival (I_CRC_CHK), VBUSOK, or BC_LVL events to host processor. |
| GND | Ground Reference | Two dedicated ground pins (pins 8 & 9) for thermal dissipation and noise isolation; must be connected to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 2 qualified with PPAP capability - validated for automotive production use in harsh thermal and EMI environments. |
| Autonomous DRP Toggle | Hardware-managed role swap between SRC and SNK without host CPU involvement during unattached state, reducing firmware overhead. |
| VCONN Switch with OCP | Integrated 560 mA max VCONN driver with 800 mA typical over-current protection and 145 °C thermal shutdown - eliminates need for external VCONN regulator. |
| USB PD 2.0 BMC PHY | Full BMC encoding/decoding, 48-byte TX and 80-byte RX FIFOs, automatic GoodCRC response, and retry/soft/hard reset handling - offloads PD protocol stack from host MCU. |
| Flexible CC Detection | Three fixed Ra/Rd comparators plus 6-bit MDAC for precise CC voltage measurement - enables accurate current capability detection and accessory mode classification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Integrated buck converter for VCONN; no autonomous DRP toggle; supports PD 3.0; 16-pin QFN. | Targets cost-sensitive consumer chargers; lacks AEC-Q100 qualification and automotive temp range. | Select when VCONN regulation is required on-chip and PD 3.0 features (e.g., Fast Role Swap) are needed, but automotive qualification is not mandatory. |
| TPS65987DRLR | Full PD 3.0 policy engine + BMC PHY + integrated LDOs; 32-pin VQFN; higher integration and BOM count. | Designed for high-end docks and monitors requiring multi-port PD management and firmware-upgradable policy logic. | Choose when full embedded PD policy engine, multiple port support, and firmware flexibility outweigh size/cost constraints. |
Compared with STUSB4500QTR and TPS65987DRLR, the FUSB302TV11MPX offers the narrowest feature set but delivers optimal balance of automotive reliability, low power consumption (25 µA standby), and minimal external component count - making it ideal for dedicated, space-constrained automotive charging applications where full PD policy engine complexity is unnecessary.

FAQ
Is FUSB302TV11MPX still recommended for new designs?
No - according to onsemi's datasheet (Rev. 7, April 2025), FUSB302TV11MPX is marked DISCONTINUED and "not recommended for new design." Engineers should contact onsemi representatives for migration paths. However, FUSB302TV11MPX remains supported for existing production with full lifecycle coordination through Aetrix Electronics.
What is the maximum VCONN current capability of FUSB302TV11MPX?
The FUSB302TV11MPX provides a VCONN switch with over-current protection set at 600–1000 mA (typical 800 mA) across the full VCONN voltage range (2.7–5.5 V). This allows safe powering of USB 3.1 full-featured cables while protecting against short-circuit faults.
Does FUSB302TV11MPX support USB Power Delivery 3.0?
No - the FUSB302TV11MPX implements USB PD 2.0 BMC physical layer only. It does not support PD 3.0 features such as Fast Role Swap, Extended Messages, or Hardware-based SOP′/SOP″ handling. Its PD compliance is limited to SOP packet exchange, GoodCRC, soft/hard resets, and basic structured VDMs.
How does FUSB302TV11MPX handle USB Type-C orientation detection?
The FUSB302TV11MPX uses dual CC1/CC2 pins to detect plug orientation by monitoring which channel presents a valid Ra (host) or Rd (device) termination. Its internal comparators and 6-bit MDAC resolve CC voltage levels to determine orientation, attach/detach state, and current capability - all before VBUS is enabled.
What I²C addressing options are available for FUSB302TV11MPX?
The FUSB302TV11MPX supports a fixed I²C slave address of 0x22 (7-bit) with no configurable address pins. It fully complies with I²C Fast Mode Plus (up to 1 MHz) and includes standard START/STOP, ACK/NACK, and repeated START protocols as defined in I²C Specification v6.
