PDIUSBD12D datasheet by Philips Semiconductors

PDIUSBD12D Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for PDIUSBD12D?
  The recommended operating temperature range for PDIUSBD12D is -40°C to 85°C, although it can tolerate storage temperatures from -55°C to 150°C.
• How do I ensure reliable data transmission with PDIUSBD12D?
  To ensure reliable data transmission, use a shielded cable, keep the cable length as short as possible, and ensure proper termination and impedance matching. Additionally, use a common mode filter or a ferrite bead to reduce electromagnetic interference (EMI).
• What is the maximum cable length supported by PDIUSBD12D?
  The maximum cable length supported by PDIUSBD12D is 3 meters (10 feet) for full-speed devices and 1.5 meters (5 feet) for low-speed devices, assuming a good quality cable with proper shielding and termination.
• Can I use PDIUSBD12D for USB 2.0 high-speed devices?
  No, PDIUSBD12D is designed for full-speed (12 Mbps) and low-speed (1.5 Mbps) USB devices only. It does not support high-speed (480 Mbps) devices.
• How do I handle overcurrent protection with PDIUSBD12D?
  PDIUSBD12D has an internal overcurrent protection mechanism that limits the current to 500 mA. However, it's recommended to add an external overcurrent protection device, such as a polyfuse or a dedicated overcurrent protection IC, to ensure safe and reliable operation.
