Product details

Overview

FUSB3307D6A0BFMX from onsemi is a USB Power Delivery 2.0-compliant adaptive source charging controller in 14-pin SOIC package, implementing full PD Policy Engine, Protocol & PHY layers with CV/CC regulation, CC1/CC2 detection, and gate drive for N-channel MOSFET load switches. It supports 3.3–21 V output voltage range, 5 A output current, and operates across −40°C to +85°C for wall chargers and AC-DC adapters.

For engineers reviewing the FUSB3307D6A0BFMX datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world protection thresholds (UVP/OVP/OCP), PPS-ready voltage control architecture, and validated alternative sourcing options for USB-C power source designs.

Technical Context

The FUSB3307D6A0BFMX integrates hardware-based USB PD 2.0 Device Policy Manager (DPM), Policy Engine, BMC transceiver, and Type-C state machines - eliminating need for external microcontroller. Its CV/CC regulation uses internal D/A converters referenced to VFB (0.33–2.0 V) and IFB inputs, enabling precise 3.3–21 V output control with ±5% tolerance.

It implements dual-path protection: adaptive UVP/OVP (60–70% and 116–127% of VCC), CC_OVP (5.5–6.0 V), VCONN_OCP (50 mA), and both internal (135°C OTP) and external (NTC-based) overtemperature detection. The 10-bit ADC monitors VBUS, IOUT, die temperature, and external NTC voltage with 90 ms debounce for E_OTP.

Key Specifications

Parameter	Value and Actual Design Meaning
USB PD Version	Compliant with USB PD 2.0 specification - supports all mandatory PD messaging, RDO negotiation, and fixed/variable PDOs without firmware dependency.
Output Voltage Range	3.3 V to 21 V (±5%) - enables full USB-C PPS-compatible programmable supply for fast-charging smartphones and laptops.
Max Output Current	5 A - determined by IS+/IS− sensing with 5 mΩ shunt; supports up to 60 W (21 V × 5 A) power delivery per ordering code.
VCC Operating Range	3.3 V to 21 V (±5%) - directly monitors and regulates power source output; includes adaptive turn-on (3.2 V) and turn-off (2.87 V) thresholds.
Protection Thresholds	UVP at 65% of VCC, OVP at 121% of VCC, CC_OVP at 5.75 V - ensures robust fault response before damage occurs in adapter or car charger applications.
Thermal Rating	Junction temperature range −40°C to +150°C; thermal resistance R_JA = 75°C/W (SOIC-14) - defines heatsink requirements for continuous 60 W operation.
CC Line Drive	330 µA source current on CC1/CC2 - meets USB Type-C specification for Rp pull-up, enabling correct sink attach detection and role negotiation.

Pinout & Package

Package: 14-pin SOIC (1.27 mm pitch), case 751A-03, RoHS-compliant, rated for −40°C to +85°C ambient operation.

Pin/Terminal	Circuit Role	Design Meaning
1 - VCC	Supply input	Monitors output voltage of power source; powers internal bias circuitry and enables VDD regulator - must be connected to VBUS via resistor divider.
2 - VDD	Internal supply rail	Regulated 5 V output (4.75–5.5 V) for internal logic; requires 1 µF capacitor to GND - supplies DPM, protocol engine, and analog blocks.
3 - GATE	Load switch driver	Drives N-channel MOSFET gate (e.g., FDMC012N03); high-voltage swing (up to 24.5 V at 21 V VCC) ensures full enhancement of low-R_DS(on) FETs.
4 - CC1	Type-C configuration channel	Detects sink attachment and negotiates PD contracts; includes 330 µA pull-up, 5.75 V OVP, and 15 pF receiver capacitance for noise immunity.
5 - CC2	Type-C configuration channel	Redundant CC line for reversible plug detection; identical electrical specs to CC1 - enables orientation-agnostic USB-C receptacle design.
6 - D+/PDIV1	BC1.2 or PD power selection	Configurable as USB 2.0 D+ (for battery charging detection) or PDIV1 (programmable PDP selection) - selected via external resistor network.
7 - D−/PDIV0	BC1.2 or PD power selection	Configurable as USB 2.0 D− or PDIV0 - used with PDIV1/PDIV2 to select among multiple pre-programmed power profiles.
8 - DISC	VBUS discharge control	Open-drain output sinking 250 mA during fault or detach; drives external 39 Ω resistor to discharge VBUS within USB-C spec limits (e.g., <221 ms).
9 - IS+	Current sense positive	Connects to high-side of 5 mΩ shunt; paired with IS− for differential current measurement - enables accurate 5 A CL regulation with 50 mA step resolution.
10 - IS−	Current sense negative	Connects to low-side of shunt; matched input impedance minimizes offset error - critical for stable constant-current mode across temperature.
11 - VFB	CV feedback input	Non-inverting input of CV error amplifier; reference voltage scales with VCC (0.33 V @ 3.3 V, 2.0 V @ 20 V) - enables 1:10 resistor divider for wide-range output sensing.
12 - IFB	CC feedback input	Non-inverting input of current loop amplifier; gain = 40 V/V - converts shunt voltage (e.g., 50 mV at 5 A) into 2 V signal for regulation loop stability.
13 - CATH	Opto-coupler interface	Drives opto-coupler cathode on secondary side of AC-DC adapters; 2 mA sink capability interfaces directly with TL431-based feedback circuits.
14 - GND	Power and signal ground	Common reference for all analog and digital blocks; must be low-impedance PCB plane - separates power return from sensitive CC/VFB paths.

Key Features

Feature	Design Value
Hardware PD 2.0 stack	Full Device Policy Manager, Policy Engine, BMC transceiver, and Type-C state machine implemented in silicon - zero firmware development required for certified PD source.
Adaptive protection	UVP/OVP thresholds scale with VCC (65%/121%), reducing false trips during dynamic load steps - improves reliability in automotive DC-DC chargers.
Integrated discharge path	DISC pin sinks 250 mA with programmable blanking (7–221 ms) - ensures VBUS drops below 0.73 V within USB-C spec (<1 s) without external timer ICs.
N-channel gate driver	GATE output swings up to 24.5 V at 21 V VCC - fully enhances low-threshold MOSFETs (e.g., NVTFS4C10N) for <15 mΩ R_DS(on) and >95% efficiency.
NTC temperature monitoring	60 µA current source on NTC pin with 90 ms debounce - enables connector or PCB temperature sensing for derating or shutdown before thermal runaway.
Small current-sense resistor	Supports 5 mΩ shunt with 40 V/V gain - reduces power loss (125 mW at 5 A) and board space vs. typical 10–20 mΩ solutions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB PD source controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STUSB4500QTR	USB PD 3.0 + PPS compliant; QFN-24; requires external MCU for custom policy logic; no integrated N-FET gate driver.	Targeted at designs needing PPS fine-grained control (20 mV steps) and higher flexibility - not drop-in compatible due to different pinout and driver architecture.	Select STUSB4500QTR only if PPS beyond PD 2.0 is mandatory and external MCU resources are available for policy customization.
MPQ4282GJ-A	Integrated DC-DC controller + PD 2.0 PHY; 20-pin QFN; combines PWM controller, gate drivers, and PD logic - no separate VCC feedback path.	Best suited for monolithic AC-DC or DC-DC designs where power stage and PD controller share same die - incompatible with opto-coupled secondary-side architectures.	Choose MPQ4282GJ-A when consolidating power conversion and PD control onto one IC; avoid if reusing existing flyback or buck-boost controller.

Compared with STUSB4500QTR and MPQ4282GJ-A, FUSB3307D6A0BFMX offers standalone PD 2.0 compliance in SOIC-14 with integrated gate driver and opto-coupler interface - making it optimal for retrofitting legacy AC-DC adapters or cost-sensitive automotive chargers without redesigning power stage topology.

FAQ

What USB Power Delivery version does FUSB3307D6A0BFMX support?

FUSB3307D6A0BFMX supports USB Power Delivery 2.0, including full Device Policy Manager, Policy Engine, Protocol, and PHY layers. It does not implement USB PD 3.0 features such as Programmable Power Supply (PPS) or extended message support - confirmed by its ordering code "D6A0BFMX" indicating PD2.0 compliance per onsemi's datasheet Table 6.

Does FUSB3307D6A0BFMX require an external microcontroller?

No, FUSB3307D6A0BFMX operates autonomously without external firmware. It embeds hardware-implemented USB PD 2.0 DPM, Policy Engine, BMC transceiver, and Type-C state machines - enabling complete PD source functionality using only passive components and a MOSFET load switch.

What is the maximum output power supported by FUSB3307D6A0BFMX?

FUSB3307D6A0BFMX supports up to 60 W output power, derived from its 21 V maximum output voltage and 5 A current limit (21 V × 5 A = 105 W theoretical, but rated for 60 W per ordering code D6A0BFMX and recommended operating conditions in Table 3).

Can FUSB3307D6A0BFMX be used in automotive applications?

Yes, FUSB3307D6A0BFMX is qualified for −40°C to +85°C ambient operation and includes NTC-based external overtemperature protection - making it suitable for automotive DC-DC chargers.
