TSB81BA3EPFP Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended for optimal thermal performance. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • Ensure that the device is operated within the recommended temperature range (–40°C to 125°C). Use a heat sink or thermal pad to dissipate heat, and consider using thermal interface materials to improve heat transfer.
  • The recommended power sequencing is to power up the VCC pin first, followed by the VDD pin. The voltage ramp-up time should be slower than 10 ms/V to prevent latch-up and ensure reliable operation.
  • Use ESD protection devices such as TVS diodes or ESD arrays on the input pins. Ensure that the device is handled and stored in an ESD-protected environment. Follow proper PCB design guidelines to prevent latch-up, such as using separate power domains and avoiding large voltage differences between pins.
  • Use a 100-ohm differential termination resistor at the receiver end, and a 50-ohm single-ended termination resistor at the transmitter end. Ensure that the termination resistors are placed close to the receiver and transmitter pins to minimize signal reflections.
