TPS2092DR datasheet by Texas Instruments

TPS2092DR Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the TPS2092DR?
  The maximum current that can be drawn from the TPS2092DR is 2A per channel, but it's recommended to limit the current to 1.5A per channel for reliable operation.
• How do I ensure that the TPS2092DR switches on and off correctly?
  To ensure correct switching, make sure to connect the EN pin to a logic-level signal (e.g., 3.3V or 5V) and use a pull-down resistor (e.g., 10kΩ) to ground on the EN pin to prevent unwanted switching.
• What is the purpose of the FLT pin, and how do I use it?
  The FLT pin is an open-drain fault indicator that goes low when an overcurrent or overtemperature condition occurs. Connect a pull-up resistor (e.g., 10kΩ) to a logic-level voltage (e.g., 3.3V or 5V) and monitor the FLT pin to detect faults.
• Can I use the TPS2092DR to switch AC loads?
  No, the TPS2092DR is designed to switch DC loads only. It's not suitable for switching AC loads, as it may not be able to handle the AC voltage and current safely.
• How do I calculate the power dissipation of the TPS2092DR?
  To calculate the power dissipation, use the formula: Pd = (VIN - VOUT) x IOUT x Rds(on). Make sure to consider the maximum junction temperature (TJ) and thermal resistance (RθJA) to ensure reliable operation.
