Product details
Overview
AP43770T16-13 from Diodes Incorporated is a USB Type-C power delivery controller for AC adapters, car chargers, and power banks, compliant with USB PD Rev3.0 V1.2 and certified for PPS (TID 1090017). It supports programmable VOUT (3.3–20V at 20mV/step), current limit up to 6A (50mA/step), built-in QC4+/QC4/QC3.0/BC1.2 auto-detection, and e-Marker cable detection via SOP' command.
For engineers reviewing the AP43770T16-13 datasheet, AP43770T16-13 pinout, AP43770T16-13 application, or AP43770T16-13 equivalent, key selection considerations include PPS resolution, integrated CC/CV control, cable-loss compensation, OTP/MTP firmware flexibility, and native support for legacy charging protocols without external protocol ICs.
Technical Context
The AP43770 implements a full USB PD 3.0 source controller with hardware-based PD message parsing, BMC transceiver, and dual-role CC line management (CC1/CC2). Its embedded MCU executes PD policy engine logic while supporting dynamic PDO negotiation, including PPS APDO with 20mV voltage and 50mA current step resolution.
It integrates analog control blocks for constant-voltage (CV) and constant-current (CC) regulation via VFB_OUT open-drain output driving an external shunt regulator (e.g., TL431), with feedback through VFB (voltage) and IFB (current) pins. Protection includes programmable OCP, UVP, OVP, SCP, and OTP with auto-restart, all configurable over the CC channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOUT Range | 3.3V to 20V, adjustable in 20mV steps - enables precise PPS compliance for fast-charging smartphones and laptops. |
| Max Output Current | 6A with 50mA step resolution - supports high-power USB PD sink devices while allowing fine-grained current limiting. |
| Input Voltage Rating | 32V max on VIN_PS - allows direct connection to 24V industrial or automotive supplies without external HV LDO. |
| Standby Current | 550µA after CC detach - minimizes no-load power loss in always-connected adapters and power banks. |
| USB PD Compliance | USB PD Rev3.0 V1.2 & PPS certified (TID 1090017) - ensures interoperability with USB-IF certified hosts and sinks. |
| Legacy Protocol Support | QC4+, QC4, QC3.0, QC2.0, BC1.2 with auto-detection - maintains backward compatibility with non-PD mobile devices without firmware reconfiguration. |
| Integrated LDOs | 5V/70mA and 1.8V outputs - powers internal logic and external interface components, eliminating need for discrete regulators. |
Pinout & Package
AP43770T16-13 is housed in a 16-pin TSSOP package (5.0mm × 6.4mm, 0.65mm pitch) with exposed thermal pad (PGND-connected) for enhanced thermal dissipation in high-power adapter designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 V5V | LDO5V output | Supplies 5V/70mA to external circuitry; requires 10µF ceramic capacitor to AGND for stability. |
| 2 IFB | Current-sense feedback input | Negative input of CC/CV current amplifier; connects to shunt resistor network for precise current regulation. |
| 3 VFB | Voltage-sense feedback input | Negative input of CC/CV voltage amplifier; sets target output voltage via resistive divider from VBUS. |
| 4 AGND | Analog ground reference | Low-noise return path for sensitive analog blocks (VFB, IFB, TS); must be separated from PGND in PCB layout. |
| 7 CC1 / 8 CC2 | USB Type-C configuration channel | Dual CC line interfaces for PD communication, cable orientation detection, and e-Marker SOP' command execution. |
| 12 PWR_ENB | External PMOS gate driver | Active-low output controlling external high-side PMOS switch; 0 = enable VBUS, 1 = disconnect power path. |
| 14 ISENP | Current sense positive input | High-side current sense node for OCP monitoring; connects to source of external sense FET or shunt resistor. |
| 16 VFB_OUT | CC/CV control output | Open-drain output driving external shunt regulator (e.g., TL431); directly controls VBUS voltage and current loop. |
Key Features
| Feature | Design Value |
|---|---|
| PPS APDO Support | 20mV/step voltage and 50mA/step current resolution - meets USB PD 3.0 PPS requirements for adaptive charging of Li-ion batteries. |
| e-Marker Cable Detection | Native SOP' command handling - identifies electronically marked cables and enforces safe current limits based on cable rating. |
| Cable-Loss Compensation | Programmable voltage offset per load condition - dynamically adjusts VFB target to maintain regulated voltage at the sink connector despite IR drop. |
| OTP/MTP Memory | One-time-programmable firmware + multi-time-programmable (4×) configuration storage - enables secure bootloader updates and field-tunable system parameters. |
| Built-in VCONN Switch | Integrated 5V VCONN supply with OCP - powers active cables without external VCONN regulator or protection circuitry. |
Applications
| AC Adapters | Car Chargers |
|---|---|
Use Scenario: Wall-mounted 65W USB PD adapter for laptop charging with multi-protocol support. IC Role / Device Role / Timing Role: Primary USB PD source controller managing PDO negotiation, CC/CV regulation, and safety protection.

IC Role / Device Role / Timing Role: Bi-directional PD source/sink controller managing input charging profile and output discharge profile with independent OCP/UVP thresholds. Use Value: Achieves <90% end-to-end efficiency in PPS mode due to zero-mismatch voltage methodology - extends usable capacity by ~8% vs. fixed-step controllers. |
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 |
|---|---|---|---|
| AP43771T16-13 | Successor with enhanced ESD rating (6kV HBM on CC pins), updated OTP firmware, and improved thermal derating above 85°C. | Required for new designs targeting USB-IF certification renewal post-2022; supports higher ambient temperature operation in enclosed enclosures. | Select AP43771 for production ramp after July 2020; AP43770 remains valid for legacy design continuity and cost-sensitive replacements. |
| STUSB4500QTR | STM32-based PD controller with ARM Cortex-M0 core; supports custom firmware but lacks native QC4+/PPS hardware acceleration. | Suitable for highly customized PD implementations requiring proprietary extensions, but adds 3–5 weeks firmware validation overhead. | Choose STUSB4500QTR only when application-specific PD extensions (e.g., vendor-defined messages) are mandatory and engineering resources permit firmware development. |
Compared with AP43771T16-13, the AP43770T16-13 offers identical PPS resolution and legacy protocol support but has lower CC-pin ESD immunity and fixed OTP firmware - making it optimal for cost-constrained, volume-sensitive adapter designs where certification recertification is not required. Versus STUSB4500QTR, it delivers faster time-to-market with zero firmware development but less architectural flexibility.

FAQ
What is the maximum input voltage rating for AP43770T16-13?
The AP43770T16-13 supports a maximum input voltage of 32V on the VIN_PS pin, enabling direct connection to 24V industrial rails or automotive systems without external HV regulation. This rating is validated per Absolute Maximum Ratings (DS41284 Rev.6, p.4) and applies under continuous operation with proper thermal management.
Does AP43770T16-13 support USB PD 3.0 Programmable Power Supply (PPS)?
Yes - the AP43770T16-13 is USB-IF certified for PPS (TID 1090017) and supports APDO with 20mV voltage steps and 50mA current steps across 3.3–20V and up to 6A. Its hardware-accelerated PPS engine handles real-time voltage/current adjustments without MCU intervention.
Can AP43770T16-13 operate without external microcontroller firmware?
Yes - the AP43770T16-13 contains embedded OTP firmware for full USB PD 3.0 source operation and requires no external MCU. Configuration is performed via MTP memory over the CC line, and legacy protocols (QC4+, BC1.2, etc.) are handled autonomously in hardware.
What is the function of the VFB_OUT pin on AP43770T16-13?
VFB_OUT is an open-drain output that drives an external shunt regulator (e.g., TL431) to close the CC/CV feedback loop. It sources/sinks current to adjust the reference voltage applied to the primary-side controller, enabling precise regulation of VBUS voltage and current without optical coupler latency.
