FUSB3307D45A0AFMNWTWG

Controllers Overview

The FUSB3307D45A0AFMNWTWG is a highly integrated USB Power Delivery (PD) controller designed for adaptive source charging applications. It implements the USB PD 3.0 and Type-C power limit state machine, supporting Programmable Power Supply (PPS) with output voltage control ranging from 3.3 V to 21 V. The device integrates constant voltage and constant current limiting modules supported by an internal D/A converter. It features comprehensive protection mechanisms including under-voltage, over-voltage, over-current, and thermal protection. An internal 10-bit A/D converter enables monitoring of output voltage, current, and temperatures via NTC resistors.

Controllers Feature Summary

• Integrates USB PD 3.0 and Type-C power limit state machine with PPS support
• Includes built-in cable drop compensation and output capacitor discharge functions
• Features flexible protection against UVLO, OVP, OCP, and thermal faults
• Supports single or back-to-back N-channel MOSFET load switching

Controllers Applications

• Wall adapters for tablet and laptop battery charging
• AC/DC PD 3.0 compliant adapters
