Product details
Overview
AP33772SDKZ-13 from Diodes Incorporated is a USB Type-C® PD3.1 sink controller supporting Extended Power Range (EPR) up to 28V and Standard Power Range (SPR)/PPS up to 21V. It operates from 3V–31V VCC, integrates CC1/CC2 configuration channel logic, provides I2C-controlled power negotiation with host MCU delegation, and delivers comprehensive protection including OVP (up to 31V), OTP, UVP, OCP, and moisture detection - deployed in portable battery-powered TCDs requiring robust, standards-compliant USB-C power intake.
For engineers reviewing the AP33772SDKZ-13 datasheet, AP33772SDKZ-13 pinout, AP33772SDKZ-13 application, or AP33772SDKZ-13 equivalent, key selection criteria include EPR/AVS voltage support, I2C register-level control of PDO selection, CC flip detection, dead-battery wake-up capability, and integrated N-MOS gate drive for VBUS-to-VOUT switching in space-constrained USB-C sink designs.
Technical Context
The AP33772SDKZ-13 implements a dedicated BMC decoder for USB PD communication on CC1/CC2 pins, enabling autonomous negotiation with PD sources while offloading policy decisions to an external host MCU via I2C. Its dual-mode protection architecture combines internal junction temperature sensing (130°C OTP threshold) and external NTC-based thermal de-rating through the OTP pin's 100μA current source.
It supports both legacy Type-A-to-Type-C charging and full PD3.1 EPR operation, with hardware-level VBUS short protection on CC pins rated to 34V. The device uses a 24-pin W-QFN4040 package with exposed thermal pad, and integrates 5V and 1.8V LDOs (V5V, V18) for internal analog/digital supply - eliminating need for external regulators in most TCD implementations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3.3V to 31V - powers IC directly from VBUS or auxiliary supply; enables dead-battery startup when VCC = 0V and V5V = 5V |
| PD Support | USB PD3.1 v1.6 certified (TID: 10062) - supports EPR/AVS up to 28V and SPR/PPS up to 21V with full PDO/APDO handling |
| OVP Thresholds | Configurable: 7V (OVP_5V), 22V (OVP_20V), 31V (OVP_28V) - hard reset + auto-restart behavior prevents latch-off during transient overvoltage |
| Protection Coverage | OVP, UVP, OCP, OTP, moisture detection - all trigger output latch-off; OTP includes internal junction sensor + external NTC interface |
| I2C Interface | Standard-mode (≤400 kHz) - bidirectional SDA/SCL with pull-up requirement; enables full register read/write for PDO selection, threshold setting, status monitoring |
| CC Pin Robustness | 34V short protection on CC1/CC2 - withstands VBUS fault coupling during hot-plug or cable misinsertion without damage |
| Package | W-QFN4040-24 (Type A1), 4.0mm × 4.0mm × 0.75mm - thermally enhanced with EPAD; RθJA = 28°C/W on 2oz FR-4 board |
Pinout & Package
AP33772SDKZ-13 is housed in a 24-pin W-QFN4040-24 (Type A1) package with exposed thermal pad (EPAD) recommended for grounding to improve thermal dissipation. Pin functions are validated per Diodes DS46176 Rev. 9-2 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ISENP | Current sense positive input | Connects to high-side of external current-sense resistor for OCP monitoring; supports precise 5mΩ shunt usage |
| 4 SDA / 5 SCL | I2C data/clock interface | Bi-directional communication with host MCU; requires external pull-ups; enables full register access for PDO control and status reporting |
| 6 FLIP | Type-C orientation indicator | Digital output: LOW = CC1 active (plug flipped), HIGH = CC2 active; eliminates need for software-based CC detection logic |
| 8 LED | Negotiation status indicator | Drives external LED with configurable patterns per Table 13; signals negotiation success/failure, voltage level, and error conditions |
| 9 INT | Interrupt request output | Active-HIGH signal alerts host MCU of events: PDO change, protection trip, or CC attachment; reduces polling overhead |
| 13 OTP | NTC bias current source | 100μA constant current output for external 10kΩ@25°C NTC; enables thermal de-rating and accurate ambient temperature tracking |
| 16 CC2 / 17 CC1 | USB Type-C configuration channel | Bi-directional BMC interface for PD negotiation; supports Rd detection, VCONN sourcing, and moisture sensing via DP/DN |
| 23 PWR_EN | N-MOS gate driver output | Active-HIGH high-voltage output (−0.3V to 38V) directly drives gate of external N-channel MOSFET for VBUS-to-VOUT switching |
| 24 VCC | Main power supply input | Accepts 3.3–31V; powers internal circuitry and LDOs; supports startup from 5V VBUS or auxiliary rail; requires 1μF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| USB PD3.1 EPR/AVS support | Enables 28V/5A (140W) power delivery to battery-powered devices without custom protocol stacks or firmware development |
| Dedicated FLIP and INT pins | Reduces host MCU GPIO count and interrupt latency by providing hardware-level cable orientation and event signaling |
| Integrated V5V and V18 LDOs | Eliminates two external regulators: V5V supplies MCU/peripherals (30mA), V18 powers internal digital core (no external load) |
| Moisture detection via DP/DN | Uses Type-C connector's DP/DN pins to detect humidity ingress - triggers protection before corrosion compromises electrical integrity |
| Dead battery wake-up | Activates immediately upon PD adapter plug-in even with 0V system battery; enables reliable cold-start in portable equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD3.1 sink controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Lacks EPR/AVS support; max 20V SPR only; no moisture detection; uses SPI instead of I2C | Suitable for legacy PD3.0 systems where 28V operation is unnecessary and moisture risk is low | Select when cost sensitivity outweighs EPR capability and moisture resilience requirements |
| MPQ4282GQ-AEC1 | Automotive-qualified (AEC-Q100); supports EPR but requires external MCU firmware for full PDO handling; no integrated LED/FLIP pins | Targeted for automotive infotainment head units needing ASIL-B compliance and extended temp range | Choose only if AEC-Q100 qualification and −40°C to +125°C operation are mandatory design constraints |
Compared with STUSB4500QTR and MPQ4282GQ-AEC1, the AP33772SDKZ-13 uniquely combines USB PD3.1 EPR certification, hardware-assisted CC flip/LED/INT signaling, moisture detection, and I2C register-level control - delivering lowest integration effort for non-automotive portable TCDs requiring 140W input resilience.

FAQ
Does AP33772SDKZ-13 support USB PD3.1 EPR without external firmware?
Yes. The AP33772SDKZ-13 embeds certified PD3.1 EPR/AVS protocol stack (TID: 10062) and handles BMC encoding/decoding, CRC validation, and message sequencing autonomously. The host MCU only selects PDOs via I2C commands like PD_REQMSG (0x31); no firmware development for PD state machine is required.
How does the moisture detection function work, and what external components are needed?
Moisture detection uses the DP and DN pins of the Type-C receptacle. When moisture bridges DP/DN, impedance drops below threshold, triggering internal comparator and protection latch-off. No external components are required beyond standard Type-C connector routing; DP/DN must be connected per USB-IF spec and not left floating.
Can AP33772SDKZ-13 operate with a 0V battery (dead battery condition)?
Yes. When VCC = 0V, the device wakes up instantly upon V5V = 5V application (e.g., from attached PD source). It initializes internal registers, asserts INT, and begins PD negotiation - enabling reliable cold-start in battery-depleted portable devices without auxiliary power rails.
What is the maximum continuous current the PWR_EN pin can drive, and what MOSFET gate characteristics are supported?
PWR_EN is a high-voltage open-drain driver rated for −0.3V to 38V. It sources no current but sinks up to 2mA (per datasheet IGPIO spec). It drives N-channel MOSFET gates directly; typical use includes 6.2kΩ pull-up to VCC and gate capacitance ≤1nF - sufficient for common 30V/50V logic-level MOSFETs with Qg < 10nC.
