Product details
Overview
FUSB302TVMPX from onsemi is an AEC-Q100 qualified, automotive-grade USB Type-C controller with integrated BMC Power Delivery 2.0 physical layer. It supports autonomous DRP toggle, SRC/SNK/DRP roles, CC attach/detach/orientation detection, and VCONN switching for full-featured USB 3.1 cables - deployed in automotive cigarette-lighter adapters and infotainment power delivery systems.
For engineers reviewing the FUSB302TVMPX datasheet, pinout, applications, or equivalent options, key selection considerations include its −40 °C to +105 °C operating range, WQFN14 2.5 mm × 2.5 mm package, I²C-configurable dual-role behavior, and integrated PD packet handling with automatic GoodCRC response and retry logic.
Technical Context
The FUSB302TVMPX implements a dedicated BMC physical layer with 48-byte TX and 80-byte RX FIFOs, enabling host-controlled USB PD 2.0 communication over CC pins. Its autonomous DRP toggle uses internal timing (tTOG1 = 30–60 ms, tTOG2 = 20–40 ms) to alternate between SRC and SNK states without processor intervention.
It integrates dual CCx comparators with programmable 6-bit DAC, fixed BC_LVL thresholds (0.20 V / 0.66 V / 1.23 V), and VBUSOK detection at 4.0 V - all supporting USB Type-C 1.2 compliance including Ra/Rd termination detection, audio/debug accessory mode, and active cable identification.

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 |
|---|---|---|---|
| STUSB4500L | Integrated USB PD 3.0 policy engine; no external MCU required for basic PD contracts; higher quiescent current (60 µA) | Targeted at cost-sensitive consumer chargers; lacks AEC-Q100 qualification and automotive temp range | Select when full embedded PD policy execution is needed and automotive qualification is not required |
| TUSB320LAIRTER | USB Type-C port controller only (no PD PHY); requires external MCU for PD protocol stack; supports 1.2–5.5 V VDD | Used in industrial docking where PD is optional; lower integration but broader supply voltage range | Select when PD is implemented in host firmware and extended VDD range is critical |
Compared with STUSB4500L and TUSB320LAIRTER, the FUSB302TVMPX uniquely combines AEC-Q100 qualification, autonomous DRP toggle, integrated BMC PD PHY, and automotive temperature operation - making it the only option qualified for production automotive USB-C power delivery systems requiring guaranteed reliability at +105 °C.

FAQ
What is the operating temperature range of the FUSB302TVMPX?
The FUSB302TVMPX is rated for −40 °C to +105 °C operation and is AEC-Q100 qualified for Grade 2 automotive applications. This extended range ensures reliable performance in under-dash and center-console environments where ambient temperatures exceed standard industrial limits. The FUSB302TVMPX maintains full functionality across this range, including CC detection accuracy, VCONN switch OCP, and BMC PD timing compliance.
Does the FUSB302TVMPX support USB Power Delivery 3.0?
No, the FUSB302TVMPX supports USB Power Delivery 2.0 only. Its integrated BMC physical layer implements the PD 2.0 specification, including GoodCRC response, soft/hard reset, and retry mechanisms. It does not support PD 3.0 features such as Fast Role Swap or extended message structures. For PD 3.0, designers must select a different controller - the FUSB302TVMPX remains fully compliant and widely deployed for 2.0-based automotive and industrial applications.
How does the FUSB302TVMPX handle VCONN power delivery for active cables?
The FUSB302TVMPX integrates a dedicated VCONN switch that routes regulated VDD (2.7–5.5 V) to either CC1 or CC2 based on plug orientation detection. It includes over-current protection (600–1000 mA) and a 1.5 ms soft-start to prevent inrush. This eliminates the need for external regulators or discrete switches - a key advantage in space-constrained automotive adapters where the FUSB302TVMPX directly powers USB 3.1 full-featured cables.
Can the FUSB302TVMPX operate in dedicated SRC mode without firmware intervention?
Yes, the FUSB302TVMPX defaults to SRC mode with CC pins floating (open) upon power-up - ideal for wall charger applications. No I²C initialization is required to function as a source. Firmware is only needed to enable DRP toggle, configure HOST_CUR levels, or activate PD messaging. This default behavior ensures immediate plug-and-play operation in charger designs, and the FUSB302TVMPX remains fully functional even if host MCU fails or is unpowered.
What I²C speed does the FUSB302TVMPX support?
The FUSB302TVMPX supports I²C Fast Mode Plus operation up to 1 MHz, compliant with version 6 of the I²C specification. This allows rapid register access for real-time PD packet handling and CC state updates. When using autonomous DRP toggle (TOGGLE = 1), the device enters low-power states between toggles, reducing effective bus bandwidth demand - a design consideration confirmed in the FUSB302TVMPX datasheet section on I²C interface timing.
