FUSB3307D6MNWTWG

Controllers Overview

The FUSB3307D6MNWTWG is a highly integrated USB Power Delivery (PD) 3.0 source controller manufactured by onsemi, housed in a 20-lead QFNW package. It implements the Source finite state machines for USB PD 3.0 and Type-C, supporting Programmable Power Supplies (PPS) with an output voltage range of 3.3 V to 21 V. The device features Constant Voltage (CV) and Constant Current Limit (CL) regulation blocks, utilizing internal D/A converters for references. It includes comprehensive protection mechanisms such as Under Voltage Protection (UVP), Over Voltage Protection (OVP), Over Current Protection (OCP), CC_OVP, VCONN_OCP, and internal/external over-temperature protection. An integrated 10-bit A/D converter monitors output voltage, current, and temperature via an NTC resistor.

Controllers Feature Summary

• Implements USB Power Delivery 3.0 v2.0 and Type-C 2.0 compliance with hardware-based Device Policy Manager and Protocol layers.
• Provides Constant Voltage and Constant Current Limit regulation with selectable feedback modes including resistor divider or Battery Charging 1.2.
• Integrates gate drivers for controlling single or back-to-back N-channel MOSFETs as load switches.
• Includes adaptive fault detection for UVP, OVP, OCP, and over-temperature conditions alongside built-in output capacitor discharging.

Controllers Applications

• Wall chargers for tablet PCs and laptop batteries
• AC-DC adapters compliant with USB PD 3.0 specifications
• DC-DC car chargers requiring individual port power control

Controllers Procurement Notes

Verify the specific ordering suffix MNWTWG corresponds to the 20-lead QFNW package and tape & reel packing method. Confirm that the D6 variant supports PD 3.0 with D+/D- functionality rather than programmable PDP selection. Ensure the component meets the required -40°C to 85°C operating temperature range for your application environment before finalizing procurement.

Controllers Selection Notes

Select this part when a fully integrated hardware solution for USB PD 3.0 source applications is required without external processing. The FUSB3307D6MNWTWG is suitable for designs needing direct control of DC-DC regulators or opto-couplers. Consider the 20-lead QFNW package for compact layouts and verify compatibility with the desired maximum power level of 60 W.

Controllers Part Context

This component belongs to the FUSB3307 family of USB Power Delivery controllers from onsemi. The D6 designation indicates support for PD 3.0 with standard D+/D- data lines. The MNWTWG suffix specifies the 20-lead QFNW package format and tape & reel packaging. This series is designed to simplify AC-DC and DC-DC adapter designs by integrating complex PD logic into a single IC.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and functional compatibility if considering alternative vendors for USB PD 3.0 source controllers.
