TPS2052DRG4 datasheet by Texas Instruments

TPS2052DRG4 Frequently Asked Questions (FAQs)

• What is the maximum current limit for the TPS2052DRG4?
  The maximum current limit for the TPS2052DRG4 is 2A, but it can be adjusted using an external resistor (RSENSE) to a minimum of 100mA.
• How do I calculate the sense resistor value for current limiting?
  The sense resistor value can be calculated using the formula: RSENSE = 0.05V / ISENSE, where ISENSE is the desired current limit.
• 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. It is an active-high input, meaning that the device is enabled when EN is high and disabled when EN is low.
• How do I handle thermal shutdown and overcurrent protection?
  The TPS2052DRG4 has built-in thermal shutdown and overcurrent protection. When the device overheats or detects an overcurrent condition, it will shut down and automatically restart when the condition is removed.
• What is the recommended layout and PCB design considerations for the TPS2052DRG4?
  Texas Instruments provides a recommended layout and PCB design guide in the datasheet, which includes guidelines for thermal management, decoupling, and routing.
