FUSB307BMPX

FUSB307BMPX is a USB Type-C port controller (Fairchild/Onsemi family) designed to manage the USB-C interface on a device. It implements the essential CC logic needed to operate a Type-C port, including:
- CC pin detection for orientation (CC1/CC2) and role determination (source/sink).
- Current advertisement and Rp/Rd handling to establish power delivery capability at the port.
- VCONN control and basic protection/monitoring for VBUS.
It is typically used as the Type-C port controller in PD-capable designs and is often paired with a PD engine or MCU that handles higher-level USB Power Delivery negotiation. The BMPX suffix denotes a specific package variant/footprint for the device.
Interface: connects to a host MCU or PD controller via a standard control interface (commonly I2C or similar) to configure the port and read status.
Applications: USB-C power adapters, power banks, docking stations, and other devices requiring a robust USB-C port controller.
For exact electrical specs, timing, and interface details, consult the FUSB307BMPX datasheet.

Common equivalents to the FUSB307B (USB‑C/CC controller) are other USB‑C/PD CC controllers such as:
- Fairchild/ON Semi FUSB302
- TI TUSB320
- STMicro STUSB4500 (or STUSB1602)
- NXP PTN5110
Note: verify pin‑out, supported PD features, I²C/firmware compatibility and package before substituting—they are functionally similar but not always drop‑in replacements.

Here are the key features of FUSB307BMPX (USB Type-C Port Controller):
- USB Type-C Port Controller with CC1/CC2 detection and orientation sensing
- VBUS switching and current-control for USB-C power delivery; supports source and sink roles
- Dead-battery support to enable charging even if the system is unpowered
- Protection: over-current/short-circuit, over-voltage and reverse-current protection; fast fault reporting
- I2C-compatible control interface for host MCU and status reporting
- Status outputs/interrupts for CC status, VBUS presence, faults, etc.
- Low quiescent current and suitable for compact, portable designs
- Small 16-pin BMPX package with recommended PCB implementation; RoHS compliant
Note: For exact electrical specs (voltages, currents, timing) and programming details, refer to the official datasheet.

Manufacturer: ON Semiconductor (originally Fairchild Semiconductor).

I don’t have live datasheet access to confirm the FUSB307BMPX package from memory. Would you like me to look it up and return the exact package type (e.g., QFN/WSON size and pin count)?
