CSD18534KCS datasheet by Texas Instruments

CSD18534KCS Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 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 the device is properly biased for optimal performance?
  Ensure the input voltage is within the recommended range (1.5V to 5.5V). Use a stable voltage regulator and decouple the input with a 1uF ceramic capacitor. Also, ensure the output is properly terminated with a 10kΩ resistor to GND.
• What is the recommended ESD protection for the CSD18534KCS?
  Use a TVS diode (e.g., SMF05C) with a 1kΩ resistor in series to protect the input from ESD events. Ensure the TVS diode is rated for the maximum input voltage.
• How do I minimize power consumption in low-power modes?
  Use the EN pin to disable the device when not in use. In shutdown mode, the device consumes less than 1uA. Also, consider using a low-power voltage regulator and optimizing the system's power management strategy.
• What is the recommended operating temperature range for the CSD18534KCS?
  The recommended operating temperature range is -40°C to 125°C. However, the device can operate up to 150°C with reduced performance and reliability.
