Product details
Overview
AP33772DKZ-13 from Diodes Incorporated is a USB Type-C® PD 3.0/PPS sink controller IC designed to negotiate power delivery from compliant sources in battery-powered or DC-input TCDs. It supports I2C-controlled PPS with 20mV/step voltage and 50mA/step current resolution, integrates OTP/MTP firmware storage, and drives external NMOS VBUS switches - enabling full PD sink functionality in compact portable electronics.
For engineers reviewing the AP33772DKZ-13 datasheet, AP33772DKZ-13 pinout, AP33772DKZ-13 application, or AP33772DKZ-13 equivalent, key selection criteria include USB PD Rev. 3.0 v1.2 compliance, I2C register-level control of RDO/APDO requests, integrated OVP/OCP/OTP protection with auto-restart, and support for dead-battery mode and fault LED indication in USB-C power interface designs.
Technical Context
The AP33772DKZ-13 implements a dedicated MCU+OTP architecture optimized for USB PD sink protocol decoding and real-time power negotiation. Its BMC transceiver handles CC1/CC2 communication with high noise immunity, while on-chip multi-channel ADC monitors VFB (voltage), IFB (current), and OTP (NTC-based temperature) for closed-loop system control.
I2C interface (slave address 0x51) enables host MCU configuration of protection thresholds (OCPTHR, OTPTHR, DRTHR), thermal resistance calibration (TR25–TR100), and dynamic RDO generation. All PD3.0 fixed PDO and PPS APDO search algorithms are executed internally, eliminating need for external protocol stack software.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | PD Rev. 3.0 v1.2 + PPS; enables 5–20V/0–5A programmable sourcing with 20mV/50mA fine-grained control. |
| Operating Voltage | VCC = 3.3V to 24V; powers IC directly from VBUS without external LDO, reducing BOM count. |
| I2C Interface | Standard-mode (400 kHz); SDA/SCL/GPIO3 used for command write, status read, and interrupt signaling. |
| Protection Features | OVP (7V/22V thresholds), OCP (configurable via OCPTHR register), OTP (NTC-based with TR25–TR100 calibration). |
| Output Control | PWR_EN pin drives external NMOS VBUS switch; supports dead-battery mode and auto-restart after fault clearance. |
| Package | W-QFN4040-24 (Type A1); 4.0×4.0 mm, 0.5 mm pitch, exposed pad for thermal dissipation (θJA = 28°C/W). |
| Firmware Storage | OTP ROM for main PD firmware; MTP ROM reserved for user configuration (e.g., thermal derating, FAULT LED behavior). |
Pinout & Package
AP33772DKZ-13 is housed in a W-QFN4040-24 (Type A1) package - 4.0 mm × 4.0 mm, 0.5 mm pitch, 24-pin, thermally enhanced with exposed ground pad. Pin 1 (ISENP) is top-left corner; pin numbering follows standard counter-clockwise sequence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ISENP | Current sense positive input | Connects to source side of 10 mΩ Rsense for OCP detection; referenced to GND for IR-drop measurement. |
| 4 SDA / 5 SCL | I2C data/clock | Enable host MCU to configure registers (e.g., RDO, OCPTHR, TEMP) and read status (STATUS, VOLTAGE, CURRENT). |
| 9 GPIO3 | Interrupt output | Active-low signal asserted on event (e.g., PDO mismatch, OVP trip, FAULT LED trigger); masks via MASK register. |
| 13 OTP | Temperature sensing current source | 100 µA constant current source for 10 kΩ NTC; ADC converts resistance to temperature (TR25–TR100 calibrated). |
| 16 CC1 / 17 CC2 | USB-C configuration channel | Detect cable orientation and communicate BMC-encoded PD messages; integrated transceiver eliminates external PHY. |
| 23 PWR_EN | NMOS gate driver output | Drives external n-channel MOSFET's gate; high = VBUS path enabled, low = disconnect; supports fast turn-off during faults. |
Key Features
| Feature | Design Value |
|---|---|
| PPS Resolution Control | 20 mV/step voltage & 50 mA/step current via I2C-configured RDO; enables precise power tuning for sensitive loads. |
| Integrated Protection Logic | OVP (auto-reset), OCP (Rsense-based, threshold configurable), OTP (NTC-calibrated), all with hardware-triggered response ≤50 µs. |
| Power-Saving Modes | Low-power idle state with <6 mA ICC_OPR; automatic entry during VBUS absence or host-suspended I2C activity. |
| Dead-Battery Support | Enables VBUS startup from 0 V input using internal charge pump; critical for devices with fully discharged batteries. |
| FAULT LED Indication | Dedicated GPIO4 output drives LED with pattern-based signaling (e.g., flicker on negotiation mismatch, solid on OVP). |
Applications
| USB-C Power Adapters | Portable Test Equipment |
|---|---|
|
Use Scenario: USB-C to barrel-jack adapter cables delivering programmable 5–20 V to legacy devices. IC Role / Device Role / Timing Role: PD sink controller negotiating exact voltage/current via PPS; manages CC line handshake and VBUS switching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD sink controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP33772S | Successor part with updated firmware, improved ESD robustness (HBM 4 kV), and extended -40°C to +105°C operating range. | Required for new designs per Diodes' notice; supports same pinout and I2C register map but adds enhanced thermal management. | Select AP33772S for production ramp; AP33772DKZ-13 is suitable only for legacy design maintenance or spare-part replacement. |
| STUSB4500 | STM32-based PD sink with embedded ARM Cortex-M0+, supports PD3.0 but lacks native PPS fine-step control (25 mV/50 mA min). | Requires external firmware development for custom RDO logic; no integrated OTP/MTP for field updates. | Choose STUSB4500 only if existing STM32 ecosystem integration outweighs loss of out-of-box PPS precision and reduced BOM simplicity. |
Compared with AP33772S, the AP33772DKZ-13 lacks extended temperature rating and HBM ESD improvement, limiting suitability for industrial environments; versus STUSB4500, it delivers plug-and-play PPS control without firmware development but offers less flexibility for proprietary PD extensions.

FAQ
Is AP33772DKZ-13 pin-compatible with AP33772S?
Yes - AP33772DKZ-13 and AP33772S share identical W-QFN4040-24 (Type A1) packaging, pin assignment, and I2C register map. The successor part maintains full hardware compatibility while adding firmware enhancements and extended environmental ratings.
What is the role of the OTP pin (Pin 13) in thermal management?
Pin 13 (OTP) provides a 100 µA constant current source to bias a 10 kΩ NTC thermistor. The AP33772's internal ADC measures resulting voltage, and firmware calculates temperature using user-loaded TR25/TR50/TR75/TR100 resistance values stored in MTP registers.
Can AP33772DKZ-13 operate without an external microcontroller?
No - the AP33772DKZ-13 requires an external host MCU to drive I2C commands (e.g., RDO writes, OCPTHR configuration, STATUS reads). It does not support autonomous PD negotiation; all power profile selection and protection settings are host-controlled via SDA/SCL/GPIO3.
Does AP33772DKZ-13 support USB-C audio accessories or data roles?
No - the AP33772DKZ-13 is a dedicated PD sink controller only. It handles CC line detection and BMC-based power negotiation but provides no USB 2.0 data path, audio accessory mode (ACA), or alternate mode (DisplayPort/Thunderbolt) support.
