TPS2054AD Frequently Asked Questions (FAQs)

  • The maximum current limit for the TPS2054AD is 1.5A, but it can be adjusted using an external resistor (RSENSE) to a minimum of 100mA.
  • The sense resistor value can be calculated using the formula: RSENSE = 0.05V / I_LIM, where I_LIM is the desired current limit.
  • The EN (enable) pin is used to turn the switch on or off. A logic high on the EN pin enables the switch, while a logic low disables it. The EN pin can be connected to a microcontroller or other logic device to control the switch.
  • The TPS2054AD has a built-in thermal shutdown feature that turns off the switch when the junction temperature exceeds 150°C. The FAULT pin is an open-drain output that goes low when a fault condition occurs, such as overcurrent or thermal shutdown. The FAULT pin can be connected to a microcontroller or other logic device to detect and respond to fault conditions.
  • The recommended PCB layout for the TPS2054AD includes placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, the sense resistor should be placed close to the device and connected to the SENSE pin using a short, low-impedance trace.
