Product details

Overview

FUSB3307D90B0AFMNWTWG from onsemi is a USB Power Delivery 3.0 adaptive source charging controller in 20-pin QFNW (4×4 mm, 0.5 mm pitch) package, implementing full PD 3.0 v2.0 and Type-C 2.0 compliance with Programmable Power Supply (PPS) support. It regulates VBUS output from 3.3 V to 21 V at up to 90 W, integrates CV/CC control loops, N-channel MOSFET gate driver, and supports CC1/CC2 communication for sink negotiation in wall chargers and automotive DC-DC adapters.

For engineers reviewing the FUSB3307D90B0AFMNWTWG datasheet, pinout, applications, or equivalent options, key selection criteria include PPS voltage range (3.3–21 V), 90 W power level, QFNW-20 thermal performance (R_JA = 36.1 °C/W), integrated OVP/UVP/OCP/NTC-based OTP, and dual-mode D+/D− BC1.2/resistor-divider configuration.

Technical Context

The FUSB3307D90B0AFMNWTWG embeds a complete hardware-based USB PD 3.0 Device Policy Manager (DPM), Policy Engine, Protocol Stack, and BMC PHY - eliminating need for external microcontroller. Its CV/CC regulation uses internal D/A converters referenced to VFB (0.33–2.06 V depending on VCC) and IFB, with current sensing via IS+/IS− inputs supporting 5 mΩ shunt and 5 A max output.

It implements adaptive protection including CC_OVP (6.0 V clamp), VCONN_OCP (50 mA), I_OTP (135 °C die threshold), E_OTP (via NTC pin), and programmable discharge timing (t_DISC1–t_DISC4 from 7 ms to 221 ms). Gate driver delivers 24.5 V high-level output at 21 V VCC, enabling direct drive of N-channel load-switch MOSFETs without external level-shifting.

FAQ

What is the maximum supported power level for FUSB3307D90B0AFMNWTWG?

FUSB3307D90B0AFMNWTWG is rated for 90 W operation, validated per its ordering code (D90B0AF), supporting up to 20 V at 4.5 A or 15 V at 6 A under USB PD 3.0 PPS contracts. This is confirmed in Table 6 of the official datasheet and distinguishes it from lower-power variants like FUSB3307D45A0AFMX (45 W) or FUSB3307D6MNWTWG (60 W).

Does FUSB3307D90B0AFMNWTWG require external firmware or a host MCU?

No, FUSB3307D90B0AFMNWTWG implements the complete USB PD 3.0 Device Policy Manager (DPM), Policy Engine, Protocol Stack, and BMC PHY in hardware. It operates autonomously without external firmware or microcontroller - a key differentiator from MCU-based alternatives like IP2726, which require custom code development and USB-IF certification effort.

What package type and thermal performance does FUSB3307D90B0AFMNWTWG use?

FUSB3307D90B0AFMNWTWG uses a 20-pin QFNW package (4×4 mm, 0.5 mm pitch, exposed thermal pad), case 484AT. Its thermal resistance is R_JA = 36.1 °C/W, enabling reliable 90 W operation on standard 2-layer PCBs without forced air cooling - significantly better than the SOIC-14 variant (R_JA = 75 °C/W).

How does FUSB3307D90B0AFMNWTWG handle VBUS discharge during detach or fault?

FUSB3307D90B0AFMNWTWG uses its DISC pin to actively discharge VBUS through an external resistor (typically 39 Ω). It supports four discharge timing modes (t_DISC1–t_DISC4) ranging from 7 ms to 221 ms, ensuring compliance with USB-C specification requirements for safe VBUS ramp-down during disconnect or overvoltage events.

Is NTC-based temperature monitoring available on FUSB3307D90B0AFMNWTWG?

Yes, FUSB3307D90B0AFMNWTWG includes the NTC pin (Pin 16), which provides a 55–65 µA current source for connecting an external NTC thermistor. This enables external over-temperature protection (E_OTP) with 90 ms debounce - a feature exclusive to the QFNW package and critical for automotive and high-ambient industrial applications.
