PD57002 datasheet by STMicroelectronics

PD57002 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
• How do I configure the PD57002 for different USB-C power delivery profiles?
  The PD57002 can be configured using the I2C interface to support various USB-C power delivery profiles, such as 15W, 27W, 45W, and 100W. The configuration process involves writing specific values to the device's registers, as described in the datasheet and application notes.
• What is the role of the VCONN pin, and how should it be connected?
  The VCONN pin is used to power the CC logic and the USB-C configuration channel (CC) pins. It should be connected to a 3.3V power supply, and a 1uF capacitor should be placed between VCONN and GND to filter out noise and ensure stable operation.
• How does the PD57002 handle fault conditions, such as overvoltage or overcurrent?
  The PD57002 has built-in fault detection and protection mechanisms, including overvoltage protection (OVP), undervoltage protection (UVP), and overcurrent protection (OCP). In the event of a fault, the device will automatically disconnect the power path and alert the system through the interrupt pin.
• Can the PD57002 be used in applications with multiple USB-C ports?
  Yes, the PD57002 can be used in applications with multiple USB-C ports. Each port requires a separate PD57002 device, and the devices can be connected in a daisy-chain configuration to share the I2C bus and reduce the number of pins required.
