Product details
Overview
AP43771VFBZ-13-FR01 from Diodes Incorporated is a USB Type-C® Power Delivery 3.1 controller with integrated 8-bit 8051-compatible MCU, preloaded with eight standard power profiles (5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A, and PPS 3.3–21V @ 20mV/step, 50mA/step), built-in OVP/OCP/SCP/OTP protection, and cable-loss compensation - deployed in single-port 65W USB PD adapters.
For engineers reviewing the AP43771VFBZ-13-FR01 datasheet, AP43771VFBZ-13-FR01 pinout, AP43771VFBZ-13-FR01 application, or AP43771VFBZ-13-FR01 equivalent, key selection criteria include OTP-resistor-based profile selection, CV/CC dual-loop control via OCDRV/VFB/IFB, CC1/CC2 e-Marker detection, and W-DFN3030-14 (Type A1) package compatibility with 3.3–24V VCC operation.
Technical Context
The AP43771VFBZ-13-FR01 implements a dual-loop analog control architecture: CV regulation uses VFB as negative input to a DAC-referenced opamp driving OCDRV; CC regulation uses IFB referenced to ISENP-sensed voltage drop across a 10mΩ shunt. Both loops converge at the open-drain OCDRV output for optocoupler-driven primary-side feedback.
It embeds a BMC physical layer for USB PD Rev3.1 V1.2 communication over CC1/CC2, supports Qualcomm QC4/4+/QC5 via HVDCP on DP/DN, and integrates a 16kB OTP memory for firmware storage - all operating within −40°C to +85°C ambient with internal thermal shutdown at +140°C junction temperature.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS | Discharge path terminal | Internal 200mA sink enables fast VBUS discharge during PDO transitions or detach events per USB PD spec |
| PWR_EN | nMOS gate driver output | Charge-pump boosted high-side gate drive for low-cost external nMOS switch; 10Ω series resistor recommended |
| VCC | Main IC supply input | Accepts 3.3–24V; requires 1μF decoupling to GND; powers internal LDOs and digital core |
| ISENP | Current sense positive input | Connects to high-side of 10mΩ shunt for precise CC loop sensing with minimal power loss |
| OCDRV | Open-drain CV/CC output | Drives optocoupler LED; combines both control loops into single feedback signal for primary-side regulation |
| GND | Analog/digital ground reference | Common return for all analog sensing, digital logic, and power paths; must be low-impedance plane |
| OTP | Profile selection interface | 100μA current source; resistor-to-ground selects one of 8 preloaded power profiles - eliminates OTP programming |
| VFB | CV loop negative input | Compares divided VBUS against DAC-set reference (e.g., 5.0V ±1.5%) to regulate constant voltage output |
| IFB | CC loop negative input | Compares ISENP voltage against DAC-set threshold to regulate constant current output with 50mA step resolution |
| CC1 / CC2 | Type-C configuration channel | Dual-channel BMC PHY for PD negotiation, Rp/Rd detection, e-Marker identification, and plug orientation sensing |
| DN / DP | BC1.2/HVDCP interface | Supports legacy USB BC1.2 and Qualcomm QC2–QC5 handshaking via D+ and D− lines |
| V5V | Internal 5V LDO output | Supplies 5V/100mA for external circuitry (e.g., level shifters, logic); requires 1μF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Preloaded 8-power-profile firmware | Eliminates field OTP programming; enables rapid BOM simplification and SKU reduction for OEM adapter production |
| Integrated CV/CC dual-loop control | Single OCDRV output merges both regulation paths - reduces external optocoupler count and improves transient response |
| Cable-loss compensation (22–42mV/A) | Actively corrects for IR drop across USB-C cables, maintaining ±1% output accuracy at full load over 2m length |
| USB-IF TID: 4305 certified | Guarantees interoperability with certified PD sinks (e.g., laptops, tablets) without protocol-level validation overhead |
| Embedded 16kB OTP memory | Stores firmware, calibration data, and device-specific parameters - enables secure, non-volatile configuration storage |
Applications
| Smartphone Fast Charging Adapter | Ultrabook USB-C Wall Charger |
|---|---|

Use Scenario: Global travel adapter supporting USB PD, QC5, AFC, and FCP protocols across US/EU/Asia markets. IC Role / Device Role / Timing Role: Multi-protocol arbiter executing sequential handshaking: first attempts PD, then falls back to QC5/HVDCP on DP/DN if CC fails. Use Value: Single-chip support for USB PD Rev3.1 + QC5 + BC1.2 eliminates need for discrete protocol IC stacking - reduces BOM cost by $0.32/unit. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Standalone PD PHY + policy engine; no embedded MCU or CV/CC control loops - requires external microcontroller and analog regulation | Used in designs where firmware flexibility outweighs integration; lacks PPS resolution (50mV/step vs. AP43771V's 20mV/step) | Select when needing custom PD extensions beyond USB-IF TID scope, but expect +3 BOM components and +4 weeks firmware bring-up |
| IP2721 | Integrated MCU + PD PHY + buck controller; includes internal power switch - not compatible with external nMOS topology | Targeted at lower-power (≤30W) all-in-one solutions; lacks cable-loss compensation and OTP-resistor profile selection | Choose for cost-sensitive sub-30W chargers where board space is critical, but avoid for 65W+ designs requiring thermal headroom and external MOSFET control |
Compared with STUSB4500QTR and IP2721, the AP43771VFBZ-13-FR01 uniquely delivers preloaded PPS-capable profiles with analog CV/CC regulation in a single W-DFN3030-14 package - enabling faster time-to-market for certified 65W USB PD adapters without MCU firmware development or external regulation ICs.
