Product details
Overview
FUSB302TV01MPX from onsemi is an AEC-Q100 qualified, automotive-grade USB Type-C controller with integrated BMC Power Delivery 2.0 physical layer, supporting SRC/SNK/DRP roles, VCONN switching up to 560 mA, and CC line detection for attach/detach, orientation, and current capability (80/180/330 µA sink or 5.1 kΩ pull-down). It operates from −40 °C to +105 °C and targets automotive cigarette-lighter adapters requiring robust, certified USB-C power negotiation.
For engineers reviewing the FUSB302TV01MPX datasheet, pinout, applications, or equivalent options, key selection considerations include its automotive temperature rating, autonomous DRP toggle timing (tTOG1 = 45 ms typ), VCONN over-current protection (800 mA typ), BMC PD packet retry logic, and I²C Fast Mode Plus (1 MHz) interface compatibility with host policy engines.
Technical Context
The FUSB302TV01MPX implements a dedicated BMC physical layer with 48-byte TX and 80-byte RX FIFOs, enabling full USB PD 2.0 packet handling-including automatic GoodCRC response, soft/hard reset generation, and retry management-under host software control via I²C. Its dual CCx channels support independent configuration for orientation detection and accessory mode (Audio/Debug).
It integrates a programmable 6-bit DAC for precise CC and VBUS voltage measurement (42 mV/step on CC, 420 mV/step on VBUS), three fixed-threshold comparators for BC_LVL detection per USB Type-C spec, and a thermal-shutdown protected VCONN switch (145 °C trip, 10 °C hysteresis) with soft-start (1.5 ms) and OCP (800 mA typ).

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 buck converter for VCONN; no autonomous DRP toggle; supports PD 3.0 but requires external VBUS OVP. | Targeted at cost-sensitive consumer chargers; lacks AEC-Q100 qualification and automotive temp range. | Select when VCONN regulation is needed on-chip and automotive qualification is not required. |
| TUSB564 | USB 3.1 Gen 2 switch + Type-C controller in single package; no BMC PD PHY; relies on host for PD negotiation. | Used in laptop docking where data switching dominates; not suitable for standalone PD negotiation in power adapters. | Select when concurrent high-speed data routing and basic CC detection are needed, but full BMC PD offload is unnecessary. |
Compared with STUSB4500L and TUSB564, the FUSB302TV01MPX uniquely combines AEC-Q100 Grade 2 qualification, autonomous DRP toggle with precise timing control, and a complete BMC PD 2.0 PHY - making it the only option validated for production automotive power delivery systems requiring guaranteed thermal and timing behavior across −40 °C to +105 °C.

FAQ
What is the operating temperature range of the FUSB302TV01MPX?
The FUSB302TV01MPX is rated for −40 °C to +105 °C, meeting AEC-Q100 Grade 2 requirements for automotive applications. This extended range ensures reliable operation in under-dash and engine-compartment-adjacent environments where ambient temperatures exceed standard industrial limits. The FUSB302TV01MPX thermal shutdown circuit disables the VCONN switch at 145 °C with 10 °C hysteresis, protecting against sustained overheating.
Does the FUSB302TV01MPX support USB Power Delivery 2.0 natively?
Yes, the FUSB302TV01MPX integrates a complete BMC physical layer for USB PD 2.0, including 48-byte TX and 80-byte RX FIFOs, automatic GoodCRC response, soft/hard reset generation, and configurable retry logic. It handles all low-level BMC signaling - bit encoding, CRC32 calculation, and 4B5B conversion - allowing the host processor to manage only the PD protocol layer via I²C. The FUSB302TV01MPX does not support PD 3.0 extensions like Fast Role Swap or Extended Messages.
How does the FUSB302TV01MPX handle VCONN power delivery and protection?
The FUSB302TV01MPX integrates a VCONN switch capable of delivering up to 560 mA with over-current protection triggered at 800 mA (typical). It features soft-start (1.5 ms), thermal shutdown at 145 °C, and hysteresis-based re-enablement at 135 °C. The switch connects VCONN to either CC1 or CC2 under I²C control, enabling compliant powering of USB 3.1 full-featured cables. The FUSB302TV01MPX does not include a VCONN regulator - an external 5 V supply is required on the VCONN pin.
Can the FUSB302TV01MPX operate as a dedicated source without external pull-up resistors?
Yes, the FUSB302TV01MPX defaults to open CC pins (no internal pull-up or pull-down on power-up), making it ideal for wall-adaptor SRC-only applications. Internal 5.1 kΩ pull-ups can be enabled via I²C register writes (PU_EN1/PU_EN2) to configure as a dedicated source. The FUSB302TV01MPX also supports programmable current capability (80/180/330 µA) through HOST_CUR bits, eliminating the need for external resistor networks to set VBUS current profiles.
What I²C speed modes does the FUSB302TV01MPX support?
The FUSB302TV01MPX supports Standard Mode (100 kHz), Fast Mode (400 kHz), and Fast Mode Plus (1 MHz) I²C operation. Its SDA pin is open-drain with 4 mA sink capability, and SCL is input-only. The FUSB302TV01MPX maintains full register accessibility and interrupt responsiveness across all supported speeds, with timing parameters verified down to 1 MHz - enabling efficient PD packet management and real-time status polling in high-throughput systems.
