TPS2552DBVR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS2552DBVR is 2.5A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
  • To ensure proper thermal management, ensure a good thermal connection between the device and the PCB, use a thermal pad or thermal tape, and consider using a heat sink or a thermal interface material.
  • The EN (enable) pin is used to turn the device on or off. To use it, connect the EN pin to a logic-level signal (e.g., from a microcontroller) to enable or disable the device. A logic high (>2.4V) enables the device, while a logic low (<0.8V) disables it.
  • Choose a sense resistor value that provides a voltage drop of 50-100mV at the maximum expected current. A higher sense resistor value can improve accuracy but increases power loss, while a lower value reduces power loss but may compromise accuracy.
  • The FLT (fault) pin is an open-drain output that indicates an overcurrent or overtemperature fault. Connect a pull-up resistor to a voltage rail, and monitor the FLT pin to detect faults. The FLT pin is active low, meaning it is pulled low during a fault condition.
