Product details

Overview

FUSB3307D6VMNWTWG from onsemi is a USB Power Delivery 3.0 adaptive source charging controller for AC-DC and DC-DC power adapters, implementing full PD 3.0 v2.0 and Type-C 2.0 compliance with Programmable Power Supply (PPS) support, 3.3–21 V output voltage range, constant voltage/constant current regulation, and integrated gate driver for N-channel MOSFET load switches. It targets automotive-grade wall chargers and car-mounted PD 3.0 adapters requiring −40°C to +105°C operation.

For engineers reviewing the FUSB3307D6VMNWTWG datasheet, pinout, applications, or equivalent options, key selection criteria include its QFNW-20 package with NTC temperature sensing, CC1/CC2 overvoltage protection up to 6 V, 5 A load switch capability, and automotive-grade thermal rating (T_J = 150°C, T_A = 105°C).

Technical Context

The FUSB3307D6VMNWTWG integrates a complete USB PD 3.0 Device Policy Manager (DPM), Policy Engine, Protocol Stack, and BMC PHY - eliminating need for external microcontroller. It implements dual-mode CV/CC regulation using internal D/A references and supports cable drop compensation via VCVR/VCCR inputs.

Its protection architecture includes adaptive UVP/OVP (60–70% and 116–127% of V_CC), CC_OVP (5.5–6.0 V), VCONN_OCP (50 mA), and dual OTP (I_OTP at 135°C, E_OTP via NTC). The 10-bit ADC monitors V_OUT, I_OUT, die temperature, and external NTC voltage with configurable debounce timing.

FAQ

What is the operating temperature range of the FUSB3307D6VMNWTWG?

The FUSB3307D6VMNWTWG is rated for −40°C to +105°C ambient temperature operation, with a maximum junction temperature of 150°C. This automotive-grade rating distinguishes it from commercial variants (e.g., FUSB3307D6MNWTWG, rated to 85°C) and enables use in vehicle cabins, enclosed industrial power supplies, and high-ambient wall chargers where thermal headroom is limited. The device includes internal OTP at 135°C and supports external NTC monitoring via the dedicated NTC pin.

Does the FUSB3307D6VMNWTWG require external firmware or a host microcontroller?

No, the FUSB3307D6VMNWTWG does not require external firmware or a host microcontroller. It integrates a complete hardware-based USB PD 3.0 Device Policy Manager (DPM), Policy Engine, Protocol Stack, and BMC PHY. All PD negotiation, state machine execution, CV/CC regulation, and protection responses occur autonomously within the IC - enabling true "zero-firmware" PD source implementation ideal for safety-critical or high-reliability applications.

How does the FUSB3307D6VMNWTWG support Programmable Power Supply (PPS)?

The FUSB3307D6VMNWTWG supports USB PD 3.0 PPS with 20 mV voltage step resolution across the full 3.3 V to 21 V range. It achieves this using internal D/A converters that generate precise CV and CL reference voltages, coupled with hardware-controlled feedback loops on VFB and IFB pins. PPS contracts are executed autonomously without external intervention, and cable drop compensation is supported via VCVR/VCCR inputs to maintain accuracy under load.

What protection features are integrated into the FUSB3307D6VMNWTWG?

The FUSB3307D6VMNWTWG integrates adaptive UVP (60–70% of V_CC), adaptive OVP (116–127% of V_CC), CC1/CC2 OVP (5.5–6.0 V), VCONN OCP (50 mA), dual OTP (internal at 135°C, external via NTC), and overcurrent protection with configurable thresholds from 50 mA to 5 A. All protections include configurable debounce and blanking times aligned with USB PD specifications to prevent false triggering during voltage transitions.

Can the FUSB3307D6VMNWTWG drive a load switch without an external gate driver?

Yes, the FUSB3307D6VMNWTWG includes an integrated gate driver on the GATE pin capable of directly driving N-channel MOSFETs in single or back-to-back configurations. It delivers up to 24.5 V gate drive at 21 V V_CC, supports fast turn-on/turn-off, and eliminates the need for external driver ICs - reducing BOM count and layout complexity. The driver is optimized for use with low-R_DS(on) MOSFETs and works seamlessly with the IC's current-sense and protection logic.
