ONET1191PRGTR datasheet by Texas Instruments

ONET1191PRGTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the device.
• How do I ensure reliable operation across the entire temperature range?
  Implement a robust thermal management system, including a heat sink and thermal interface material. Ensure proper airflow and avoid thermal hotspots.
• What are the critical timing parameters for the device's power-up sequence?
  The power-up sequence should follow the recommended timing diagram in the datasheet. Ensure a minimum 10 ms delay between VCC and VDD power-up, and a 100 ms delay between VDD and EN pin assertion.
• How do I optimize the device's power consumption for low-power applications?
  Use the device's power-down mode, disable unnecessary features, and optimize the clock frequency. Consider using a low-dropout regulator (LDO) to reduce power consumption.
• What are the recommended ESD protection measures for the device?
  Implement ESD protection diodes on all input and output pins. Use a TVS (transient voltage suppressor) diode on the power supply lines and ensure a minimum 1 kΩ series resistor on all input pins.
