USBPDSINK01 - USB Power Delivery sink controller

The MLAB module USBPDSINK01 is a powerful module containing the STUSB4500 power-delivery sink controller. The module is designed to provide a flexible and reliable solution for various applications requiring USB power delivery PD2 and PD3 protocols.

Specifications

STUSB4500 is a USB-C PD controller for Power Sinks / UFP (on the device side). It is certified by the USB-IF consortium for USB Type-C and USB Power Delivery applications (USB-C & USB PD).

Module Features

  • USB-C Input: The module accepts power through the USB-C connector.
  • Power Output: The output is led to a pin header and also to a WAGO terminal block to high-power tool-free connection of powered devices.
  • Indicator Pins with LED: Some status pins contain LEDs, and these signals are connected to the pin header.
  • Pull-up Resistors: The module has pull-up resistors on the output signals for fast implementation into your system. PullUp voltage can be attached to header pins or can be used internal 3v3.
  • Integrated LDO: The module is equipped with an integrated LDO for powering pullups and LED (no output).
  • External Power Supply: The VSYS power can also be attached externally.
  • Communication via I2C: The module communicates via I2C bus.
  • Key Features of STUSB4500:
    • Auto-run USB Type-C™ and USB PD sink controller handling and detection
    • Dead battery mode support
    • Up to 3 configurable sink PDO profiles (with permanent memory)
    • Integrated VBUS switching gates (PMOS transistor)
    • Integrated VBUS voltage monitoring
    • Internal and/or external VBUS discharge paths (for high capacitance networks)
    • Short-circuit protection on VBUS pins (22 V)
    • High-voltage capability on VBUS pins (28 V)
    • Dual power supply (VSYS and/or VDD): VDD = [4.1 V; 22 V] or VSYS = [3.0 V; 5.5 V]
    • Accessory mode support
    • Temperature range: -40 °C to 105 °C
    • ESD: 3 kV HBM - 1.5 kV CDM
    • Certified: USB Type-C™ rev 1.2, USB PD rev 2.0 (Official Test ID: TID #1000133)
    • Interoperable with USB PD rev 3.0

Pinout and Their Meaning

  • ALERT: Notification of various states and events.
  • USB-C orientation: Indication of the connected side of the USB-C cable.
  • CONNECTED: Cable connection indication.
  • GPIO: General input/output pin, configurable for various purposes.
  • OK2 & OK3: Pins that are active when the corresponding PDO is selected. Can indicate the selected voltage.
  • RESET: Pin for resetting the USB-PD controller.

Possible Applications

The MLAB module USBPDSINK01 is ideal for a wide range of applications, including:
