TPS2085DR datasheet by Texas Instruments

TPS2085DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2085DR?
  The maximum input voltage that can be applied to the TPS2085DR is 5.5V, although it's recommended to keep it below 5V to ensure reliable operation.
• How do I ensure the TPS2085DR is properly powered up and configured?
  To ensure proper power-up and configuration, follow the recommended power-up sequence: VCC, then EN, and finally IN. Also, make sure to connect the EN pin to a valid logic level (either VCC or GND) to avoid undefined behavior.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the device on or off. When EN is high (VCC), the device is enabled, and when EN is low (GND), the device is disabled. Use the EN pin to control the power state of the TPS2085DR, especially in low-power or battery-powered applications.
• How do I handle the thermal shutdown feature of the TPS2085DR?
  The TPS2085DR has a built-in thermal shutdown feature that turns off the device when it overheats. To handle this, ensure good thermal design and heat dissipation, and consider adding thermal monitoring and shutdown detection circuitry to your design.
• What is the recommended layout and PCB design for the TPS2085DR?
  For optimal performance and thermal management, follow Texas Instruments' recommended PCB layout and design guidelines, including using a solid ground plane, minimizing trace lengths, and placing the device near a heat sink or thermal pad.
