Product details
Overview
AP43771ZFBZ-13 from Diodes Incorporated is a USB Type-C® Power Delivery 3.1 controller IC with integrated 8-bit 8051-compatible MCU, supporting PPS (20 mV/step), QC4/4+/5, BC1.2, and HVDCP protocols. It delivers up to 65W via single-port USB PD charger designs using standard firmware, implements CV/CC regulation via optocoupler feedback, and embeds OVP/OCP/SCP/OTP protection. Its W-DFN3030-14 (Type A1) package enables compact AC-DC adapter implementations.
For engineers reviewing the AP43771ZFBZ-13 datasheet, AP43771ZFBZ-13 pinout, AP43771ZFBZ-13 application, or AP43771ZFBZ-13 equivalent, this device serves as a certified (USB-IF TID: 4305), production-ready USB PD source controller for fixed-profile chargers requiring robust cable-loss compensation, e-Marker detection, and resistor-selectable power profiles (5V/9V/12V/15V/20V).
Technical Context
The AP43771ZFBZ-13 integrates a BMC physical layer for USB PD Rev3.1 V1.2 communication over CC1/CC2, supports PPS APDO with 20 mV voltage resolution and 50 mA current resolution, and uses dual op-amp-based CV/CC loops referenced to VFB (±0.5% 5V/9V/12V reference accuracy) and IFB with 10 mΩ current-sense resistor interface. Its OTP pin enables resistor-programmable selection among eight preloaded PD profiles.
It features a dedicated nMOS gate driver (PWR_EN) with internal charge pump, VBUS discharge path (~200 mA sink), and embedded ADC for temperature monitoring via NTC on OTP pin. Protection logic includes 50 µs OVP response, 30 ms UVP delay, and auto-restart SCP with 0.8 s restart interval - all implemented in hardware without MCU intervention.

Pinout & Package
AP43771ZFBZ-13 uses the W-DFN3030-14 (Type A1) 3.0 mm × 3.0 mm, 0.5 mm pitch, exposed pad package - optimized for thermal dissipation in space-constrained USB PD adapters.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VBUS | Discharge path terminal | Internal 200 mA sink enables fast VBUS discharge during PDO transition or detach per USB PD spec |
| PWR_EN | nMOS gate driver output | Charge-pump boosted high-side gate drive for cost-effective discrete nMOS switch control |
| VCC | Main supply input | 3.3–24 V operation; requires 1 µF decoupling to GND; powers all analog/digital blocks |
| ISENP | Current sense positive input | Connects to high-side of 10 mΩ sense resistor for accurate CC loop with minimal loss |
| OCDRV | Open-drain CV/CC output | Drives optocoupler LED to close primary-side feedback loop - eliminates secondary-side TL431 |
| GND | Analog/digital ground | Single ground plane required; exposed pad must be soldered for thermal and EMI performance |
| OTP | Profile selection / NTC interface | 100 µA current source: resistor to GND selects one of eight preloaded PD profiles (FR01 firmware) |
| VFB | CV feedback input | Negative input of CV op-amp; sets output voltage via resistor divider from VOUT (e.g., 5V/9V/12V) |
| IFB | CC feedback input | Negative input of CC op-amp; sets output current via ISENSE voltage drop across 10 mΩ |
| CC1 / CC2 | Type-C configuration channel | Dual CC pins detect cable attach/detach, orientation, e-Marker presence, and negotiate PD roles |
| DN / DP | USB 2.0 data lines | Support HVDCP (QC/AFC/FCP/SCP) negotiation via D+/- signaling when PD not active |
| V5V | Internal 5V LDO output | 1 µF decoupled output powers external circuitry (e.g., level shifters, logic) - no external regulator needed |
Key Features
| Feature | Design Value |
|---|---|
| Preloaded 8-PD-profile firmware | Eliminates OTP programming; resistor on OTP pin selects profile - reduces BOM and manufacturing complexity |
| Integrated CV/CC control loops | Dual op-amps with DAC-set references enable stable, isolated regulation without secondary-side ICs |
| Cable-loss compensation | Adjustable 22–42 mV/A compensation (0–7× step) corrects for voltage drop across long cables |
| e-Marker detection via SOP command | Hardware-level SOP packet generation ensures reliable identification of electronically marked cables |
| Built-in VBUS discharge path | ~200 mA internal sink meets USB PD spec timing for VBUS ramp-down during detach or fault |
| Robust protection suite | OVP/UVP/SCP/OTP with hardware-triggered nMOS turn-off - no firmware dependency for safety-critical responses |

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 | 48-pin QFN; requires external MCU for PPS; no integrated CV/CC op-amps; relies on external shunt reference | Needs secondary-side feedback components (TL431, opto) and firmware development for profile selection | Choose when system already uses ST ecosystem and requires multi-port coordination via I2C |
| IP2726 | W-QFN4040-24; supports I2C for dual-port power sharing; lacks resistor-based OTP profile selection | Designed for multi-port chargers with dynamic load balancing; no FR01-style fixed-profile option | Choose for dual-C-port designs needing real-time power re-allocation between ports |
Compared with STUSB4500QTR and IP2726, AP43771ZFBZ-13 offers plug-and-play 8-profile selection without MCU coding, integrated CV/CC op-amps eliminating secondary-side components, and faster OVP response - making it optimal for cost-sensitive, single-port, certified USB PD adapters.

FAQ
What USB PD specifications and protocols does AP43771ZFBZ-13 support?
AP43771ZFBZ-13 supports USB PD Rev3.1 V1.2 with full PPS (up to 21V), QC4/4+/5 (certified TID: QC20201127203), BC1.2, HVDCP, AFC, FCP, and SCP. It implements BMC physical layer, SOP command for e-Marker detection, and hardware-based protocol handshaking - no firmware updates required for protocol compliance.
How is power profile selection implemented on AP43771ZFBZ-13?
Power profile selection uses the OTP pin's 100 µA current source: connecting a resistor from OTP to GND selects one of eight preloaded PD profiles (e.g., 5V/3A, 9V/3A, 12V/5A). Resistance values are defined in DS42883 Rev8-2 Table 10; no OTP programming or firmware flashing is needed - enabling field configurability and simplified inventory.
Does AP43771ZFBZ-13 require an external microcontroller?
No. AP43771ZFBZ-13 integrates an 8-bit 1T 8051-compatible MCU with 16 kB OTP memory, enabling full USB PD protocol stack execution, CV/CC loop control, protection sequencing, and ADC-based temperature monitoring - all without an external host MCU.
What protection features are implemented in hardware versus firmware?
OVP, UVP, SCP, and OTP are implemented in analog hardware with direct nMOS gate control (PWR_EN), ensuring ≤50 µs OVP response and 0.8 s SCP auto-restart - independent of MCU execution. Cable detection, e-Marker SOP, and PPS negotiation run in firmware, but safety-critical protections remain fail-safe and deterministic.
