Product details
Overview
FUSB307BVMPX from onsemi is an automotive-grade USB Type-C Port Controller (TCPC) with integrated USB Power Delivery (PD) Rev 3.0 Ver 1.1 support, 10-bit VBUS ADC, and dual-role port (DRP) functionality. It autonomously handles BMC PD packet transmission/reception, GoodCRC response, and VBUS source/sink control via dedicated SNK/SRC outputs. Designed for dead-battery operation, it powers TCPMs from VBUS and delivers regulated 3.3 V via its internal LDO.
For engineers reviewing the FUSB307BVMPX datasheet, pinout, applications, or equivalent options, key selection considerations include its −40°C to +105°C automotive temperature rating, QFN-16 package with CC1/CC2/INT_N/SCL1/SDA1 interface signals, VCONN switching capability, and I²C-addressable configuration supporting four slave addresses.
Technical Context
The FUSB307BVMPX implements a full BMC physical layer with autonomous transmit/receive state machines, automatic GoodCRC generation for valid SOP* messages, and hardware-accelerated Hard Reset/Cable Reset signaling. Its Type-C Rev 1.3 detection circuitry supports manual attach/detach sensing and orientation detection via ORIENT pin.
It integrates VBUS monitoring (10-bit ADC), programmable VCONN current limiting (210.5 mA default or configurable), and dual GPIOs configurable as CMOS I/O or open-drain outputs. Power management includes dead-battery startup from VBUS, LDO bypass at VDDGOOD threshold, and auto-discharge control for both source and sink paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB7320RGET | USB 3.1 Gen 1 hub + integrated TCPC; larger 40-pin QFN; no VCONN switch; requires external VBUS switches. | Targeted at USB hub + PD combo designs; lacks automotive temp grade and dead-battery LDO output. | Choose TUSB7320RGET only if USB data multiplexing is required alongside PD control; not drop-in for FUSB307BVMPX standalone TCPC use cases. |
| STUSB4500LQTR | USB-PD 3.0 controller with integrated VBUS switch drivers; 20-pin QFN; no VCONN switch; 12-bit VBUS ADC; −40°C to +85°C rating. | Optimized for consumer AC adapters; lacks automotive qualification and orientation-detection GPIO (ORIENT pin). | Select STUSB4500LQTR for cost-sensitive consumer chargers where extended temperature range and VCONN are non-critical. |
Compared with TUSB7320RGET and STUSB4500LQTR, the FUSB307BVMPX uniquely combines automotive temperature range, integrated VCONN switching, dead-battery LDO, and minimal 16-pin footprint-making it the only option qualified for under-hood or dashboard-mounted USB-C charging systems requiring full PD 3.0 feature parity.

FAQ
What is the operating temperature range specified for the FUSB307BVMPX?
The FUSB307BVMPX is rated for −40°C to +105°C operation, meeting automotive under-hood and cabin environmental requirements. This extended range distinguishes it from commercial-grade variants like FUSB307BMPX (−40°C to +85°C) and ensures reliable performance in high-thermal-stress vehicle applications.
Does the FUSB307BVMPX integrate a VCONN power switch, and what is its capability?
Yes, the FUSB307BVMPX integrates a CCx-to-VCONN switch capable of delivering up to 3 W to active USB-C cables and accessories. It supports programmable overcurrent protection via the VCONN_OCP register and automatically selects CC1 or CC2 based on orientation detection, eliminating need for external analog switches.
How does the FUSB307BVMPX support dead-battery operation in portable systems?
The FUSB307BVMPX powers itself from VBUS during dead-battery conditions and supplies a regulated 3.3 V LDO output (LDO pin) to boot the TCPM or microcontroller. Once VDD rises above VDDGOOD, the internal LDO bypasses and the device transitions to VDD power-enabling seamless system wake-up without external bias rails.
What I²C addressing options are available for the FUSB307BVMPX, and how are they selected?
The FUSB307BVMPX supports four I²C slave addresses (0x50–0x53), selected at power-up by pulling the ORIENT/I2C_ADDR pin high or low and routing SCL/SDA to either SCL1/SDA1 or SDA1/SCL1 pairs. This enables multi-port systems to address multiple FUSB307BVMPX devices on a shared I²C bus without address conflict.
Can the FUSB307BVMPX perform autonomous DRP toggling, and what signals indicate its status?
Yes, the FUSB307BVMPX performs autonomous DRP toggling when ROLECTRL.DRP = 1b. Its status is reported in the CCSTAT register: CCSTAT.LOOK4CON = 1b indicates active toggling, CCSTAT.CON_RES = 0b means source mode detected, and CCSTAT.CON_RES = 1b indicates sink mode-readable via I²C after INT_N assertion.
