TPS2104DBVR datasheet by Texas Instruments

TPS2104DBVR Frequently Asked Questions (FAQs)

• What is the maximum current that the TPS2104DBVR can handle?
  The TPS2104DBVR can handle a maximum current of 2A per channel, making it suitable for powering small to medium-sized loads.
• How do I ensure that the TPS2104DBVR switches between the two input sources seamlessly?
  To ensure seamless switching, it's essential to ensure that the input voltage difference between the two sources is within 100mV, and the input voltage rise and fall times are slower than 10ms.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. You can use the EN pin to control the power-up and power-down sequencing of your system.
• How do I handle the situation where one of the input sources fails or is disconnected?
  The TPS2104DBVR has built-in undervoltage lockout (UVLO) and overvoltage protection (OVP) features that help protect the device and the load in case of input source failure or disconnection. You can also use external circuitry to detect input source failure and take appropriate action.
• What is the typical power-on reset (POR) time for the TPS2104DBVR?
  The typical POR time for the TPS2104DBVR is around 2ms, which is the time it takes for the device to stabilize and start switching between the input sources after power-on.
