TPS2491DGSRG4 datasheet by Texas Instruments

TPS2491DGSRG4 Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2491DGSRG4?
  The maximum current rating of the TPS2491DGSRG4 is 1.5A.
• How do I ensure the TPS2491DGSRG4 is properly powered on?
  To ensure the TPS2491DGSRG4 is properly powered on, make sure the input voltage (VIN) is within the recommended range (2.7V to 5.5V), and the enable pin (EN) is high.
• What is the purpose of the fault pin (FLT) on the TPS2491DGSRG4?
  The fault pin (FLT) is an open-drain output that goes low when the device detects an overcurrent, overvoltage, or undervoltage condition.
• How do I set the current limit on the TPS2491DGSRG4?
  The current limit on the TPS2491DGSRG4 can be set by connecting a resistor (RILIM) between the ILIM pin and GND. The current limit is calculated as 1.5A / (RILIM / 1000).
• What is the thermal shutdown temperature of the TPS2491DGSRG4?
  The thermal shutdown temperature of the TPS2491DGSRG4 is typically 150°C.
