TPS2021DR datasheet by Texas Instruments

TPS2021DR Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2021DR?
  The maximum current rating of the TPS2021DR is 2A per channel, with a total current limit of 4A for both channels combined.
• How do I ensure proper thermal management for the TPS2021DR?
  To ensure proper thermal management, make sure to provide adequate heat sinking, use a thermally conductive PCB material, and keep the device away from heat sources. The maximum junction temperature is 150°C.
• What is the minimum input voltage required for the TPS2021DR?
  The minimum input voltage required for the TPS2021DR is 2.7V, but it's recommended to use a minimum of 3V to ensure proper operation.
• Can I use the TPS2021DR in a high-temperature environment?
  Yes, the TPS2021DR is rated for operation up to 125°C, but the maximum junction temperature is 150°C. Make sure to derate the current output accordingly based on the ambient temperature.
• How do I protect the TPS2021DR from overvoltage and undervoltage conditions?
  Use a voltage regulator or a voltage supervisor to protect the TPS2021DR from overvoltage and undervoltage conditions. The device has built-in overcurrent protection, but it's still recommended to add external protection for added reliability.
