TPS2552DRVT-1 datasheet by Texas Instruments

TPS2552DRVT-1 Frequently Asked Questions (FAQs)

• What is the maximum current that the TPS2552DRVT-1 can handle?
  The TPS2552DRVT-1 can handle a maximum current of 2.5A, but it's recommended to limit the current to 1.5A for reliable operation.
• How do I ensure the TPS2552DRVT-1 is properly powered on?
  To ensure proper power-on, the EN pin should be driven high (above 1.4V) and the input voltage (VIN) should be within the recommended range (2.5V to 5.5V).
• What is the purpose of the FLT pin?
  The FLT (Fault) pin is an open-drain output that indicates an overcurrent or overtemperature fault condition. It can be used to trigger an interrupt or reset in the system.
• Can I use the TPS2552DRVT-1 as a high-side switch?
  No, the TPS2552DRVT-1 is a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications.
• How do I calculate the power dissipation of the TPS2552DRVT-1?
  Power dissipation can be calculated using the formula: Pd = (VIN - VOUT) x IOUT. Make sure to consider the thermal resistance and junction temperature to ensure reliable operation.
